Leo, short for Leonard, known as Rua or Lua in the Japanese version (see below), is Luna's twin brother, and was one of the Signers who possessed the Heart Mark of the Dragon (as well as the only other Signer aside from Yusei, who has been able to weaken the "Meklord Emperors"[5][6][7]). He and Luna aid Yusei Fudo, whom they admire and support, in his Duels. Leo is the older twin of the two and has a lively and blundering personality. He and his sister also have a mini series in the Dark Signers arc before each episode known as Card of the week.

Lua's Lineart Lineart.

Leo's outfit is similar to his sister's; it consists of a short-sleeved white jacket over a sleeveless dark blue shirt with golden markings that differ from Luna's shirt. He also wears white shorts with a dark blue belt and blue sneakers of the same color. Leo also has a bracelet on each wrist, and his blue-green hair is pulled into a single, high ponytail with two shoulder-length bangs on both sides of his face but when he doesn't wear it up (like when he's sleeping) it looks like Luna's in the same situation. He carries a Duel Disk with a blue and white trim on his left arm, which was originally too big to fit until Yusei modified it.

On formal occasions, he wears a blue suit with a white shirt and blue bowtie under the jacket, and black loafers with white, knee-high socks. When he's sleeping, he wears light blue pajamas. If at school, he wears the New Domino academy boys uniform with a green book-bag.


Leo is a lively character (in the dub he is very carefree and acts dumbly), but is shown to get serious when the situation calls for it. Occasionally he will doubt his skill but his sister Luna always looks towards him for encouragement. He started off as cocky and sure of himself, but became more mature and careful as the series progressed.

He is also shown to be very perceptive in season 2, as he immediately felt something was not right about Lester even when he had not acted suspicious yet.[8] He is also shown to not hold grudges against those who harm his sister if they change their ways, such as with Aporia.[9]


Although he seems ordinary at first glance, Leo has some sort of ability in which he can somehow talk to Luna, even if she's in the Spirit World. This also awoke her from her coma when she was 3 years old. He also can get in the Spirit World if Luna repeatedly calls out to him while she's there, as seen during the Duel with Frank. When Luna had been hypnotized by Frank, Leo entered a trance too (for unexplained reason), and eventually fell unconscious after constantly calling out to Luna. However, he does not appear to be aware of any of this yet.[10][11]


Rua-Ruka linework Linework by Kazuki Takahashi.

Lua and Luca files "Lua and Luca's" names in the Japanese anime

Linework by Kazuki Takahashi has revealed the Japanese names of the twins to be Rua and Ruka. However when their names appeared wrote out in the Japanese anime, they were Lua and Luca. The differing in names are due to Japanese speakers pronouncing "L" and "R" as the same sound. When he Dueled Haley in the Japanese anime, his name was spelled Rua. When the twins Dueled Lester their names were spelled Lua and Luca.

The 4Kids Entertainment website initially listed the twins in the character section. Here Lua has his name changed to Luka, while Luca has hers changed to Luna. Both characters have since been removed from that section of the website.

His name was changed to Leo, short for Leonard, when he appeared in the English anime.


Leo lives together with Luna in the Tops residential area. They spend most of their time alone together as their parents are usually at work. They are educated via the internet, so they spend most of their time inside. Later, both he and his sister attend Duel Academy.

Fortune CupEdit

Lua Duel Disk Leo Dueling Yusei with his original over-sized Duel Disk.

Luna was able to sense Yusei when he was shocked by the police officers, so she and Leo rescue him after his Duel with Trudge and took him to their home. Yusei wanted to leave, fearing he may place them in danger, but Leo talks him into a Duel. After Yusei wins, they manage to persuade him to stay for the night. (In the English dub, Yusei had lost his memory and Dueled Leo to help him remember.)

Leo and Luna awaken the next morning to find that Yusei had left after modifying their Duel Disks to fit their small arms. Leo then leaves with Dexter to find and Duel the Black Rose. They eventually meet up with Yusei again, and shortly afterward the Black Rose appears, but leaves after seeing Yusei's Mark of the Dragon, which seems to disgust her. Leo shows fear for both the Black Rose and the Mark.

Pretty lady Leo disguised as Luna during the Fortune Cup, first round.

Luna was selected as someone to participate in the Fortune Cup, but because she didn't feel like participating, Leo planned to disguise himself as her and compete instead, and Luna adds the saying "Leo wears makeup!". The next day, Leo enters the Fortune Cup in disguise as Luna, but quickly loses to Greiger after a hard-fought Duel. Using Zigzix's Signer-detecting technology, Lazar determines that Greiger Dueled Leo instead of Luna. During the consolation Duel where Luna Dueled Professor Frank, Leo was hypnotized along with his sister and later reveals to her that he had unconsciously given himself the task of protecting her while she protects the Duel Monsters Spirit World. He was awakened from his trance when the Duel ended.

At the end of the first day of the Fortune Cup, it is shown that Yusei would be paired against Greiger the next day. As Bolt Tanner wondered what kind of Duel Runner Greiger had, Leo tried to find out and ran off. He snuck into Greiger's garage, and got frightened by the look of Greiger's Duel Runner. His scream triggered a security alarm, locking him in the garage, where he slept until Greiger returned and found him sleeping.

Dark SignersEdit

At the end of the Fortune Cup, Leo, along with his sister, learns what a Signer is. He is worried about Yusei going by himself to Satellite after what the Dark Signer said.

After Yusei's Duel with Kalin Kessler, Tanner and Yanagi arrive at their home as they discuss the current situation. They are worried about whether Yusei had already fought against a Dark Signer or not. Then he asks Luna if it's true that "Power Tool Dragon" battled alongside the other Signer Dragons against the Earthbound Immortals, to which she responds that it may have. Leo immediately assumes himself to be the Fifth Signer and proclaims that he must also protect Luna as well. Yanagi re-asks and Luna says she only said yes to cheer up Leo.

In order for all the Signers to work together to fight the Dark Signers, Leo proposes that they seek help from Akiza. As they accept, he learns about the Arcadia Movement. Leo along with Luna, Bolt, and Yanagi, then go in search of Akiza. Upon reaching the Arcadia Movement base, they are tricked by Sayer. Leo then wakes up chained, and is made to Duel Sayer as a test in order to determine if he possesses any sort of ability, since he is Luna's twin brother.

Leo also learns that Sayer plans to use his psychic Duelists as soldiers in a war against the world for all the discrimination they have taken. As the Duel progresses, Sayer attacks Leo directly, making him cry, however he tells him not cry and instead fight. Due to the fact that he has revealed his true purpose, Leo's life is at stake now, and in order to save himself, he must awaken his hidden abilities.

Despite his determination after Summoning "Power Tool Dragon", the Duel ends in Sayer's victory. Leo then falls to the floor and passes out. He is later seen on a bed, with Luna watching over him. He and Luna are then rescued by Tanner and Yanagi, and before being able to leave the building they all witnesses the Duel between Akiza and Misty Tredwell.

After the building begins to collapse due to the Earthbound Immortal's assault on it, Tanner takes the two of them outside to safety. After Akiza lands in the hospital in a comatose state, Leo, along with Luna, as well as Jack are present within. As with the rest of the people there, he witnesses the Duel between Yusei and Akiza.

After it concludes with Yusei's victory, Leo tags along with Luna and the other Signers as they are invited by Rex Goodwin into his place, as he wants to reveals to them some secret concerning the Crimson Dragon, as well as some sort of deep connection between them and the Dark Signers. There he learns about their own "fate" which is responsible as for that the Signers to have met in someway. Leo finally learns that the Fifth Signer was already awakened long ago and that it will appear later on, and also about the Dark Signer's true identity involving the Netherworld, their abilities, and use of Earthbound Immortals.

After that Leo seems to accept the fact that he is not a Signer, he tells Luna that then there's no reason for him to go with them to Satellite, as the only thing he could if he did is to get in their way. However his sister tells him that he doesn't need to be a hero, just to be there to protect her as he promised from the start, that being the reason of why he accompanies her and the other Signers to Satellite.

Akiza, Leo, and Luna eventually meet up with Yusei and Jack, giving Yusei a morale boost and support so he will hopefully change his mind about refusing to Duel Kalin by saying that they will all fight along his side. Yusei and Jack both have friends to fight for, along with the protection of Satellite and New Domino City. An argument between Jack and Leo breaks out, as Leo says that he will definitely become cool like Yusei and Jack, but Jack insists that Leo will never become cool.

Afterwards, the Dark Signers perform some kind of dark ritual within Satellite, not only enclouding but also somehow vanquishing its other Satellite residents. Because of this, the Signers, along with Leo and Mina, all board a helicopter to Satellite being flown by Trudge himself. When they all arrive to Satellite they are greeted by Martha. However, the reunion is cut short as Yusei finds out that Rally, Crow, and the others have disappeared. Later during dinner, Roman suddenly appears, demanding to Duel. As Yusei accepts to Duel, accompanied by Akiza, Jack and everyone else take Martha and the kids to a safer place. As Roman and Yusei's Shadow Duel is about to begin, Luna, Leo, and Jack become aware of it as their Marks of the Dragon began to react.

After Yusei's match against Roman concludes, Jack, Akiza, and Luna, along with Leo, are present as the rest of the Dark Signers reveal themselves. Later on, as each one of the Signers is set on defeating their respective opponent, they split up to each of the four control units of the Original Ener-D Reactor. As Luna and Leo are taken by Trudge to where Devack is waiting, she instead travels into the Duel Monsters Spirit World in order to free Ancient Fairy Dragon. Due to this, Leo bravely challenges Devack to a Duel in her place, as he is determined to fulfil his promise of protecting her.

Despite Devack's warning that Leo isn't a Signer, and therefore he won't be able to beat him, the Duel begins and Devack is able to quickly inflict damage to him. However, Leo counterattacks by Synchro Summoning "Power Tool Dragon", his ace card. Devack then unleashes his Dark Synchro Monster, "Zeman the Ape King".

Leo, after getting a strategy together, is able to push Devack back by destroying "Zeman the Ape King". He gets backed into a corner again when Devack summons "Earthbound Immortal Cusillu". After Luna comes back, she sees her brother in trouble and takes over for Leo as a way of making it up to him. She and Leo howver devack paly trap that lot him take all leo and luna monster atk point luna sya no he cant leo say o no the devack die brats leo life points hit 0 and both the twins yell cough up spit and there eyes go blank leo loses asjack shrit and shoes luna lsoe her jacke and shoes btoh tiwns hit the ground dead devack laughs at them yusei in raged duel devack wins bringing the twins back

After Crow's Shadow Turbo Duel against Greiger ends, Leo, along with Luna, and Trudge are all currently witnessing the rematch between Yusei and Kalin. After the extreme Duel between the 2 finally ends, Leo, Luna, and Trudge accompany Yusei as he decides to go to the Original Ener-D Reactor directly in order to Duel against Roman one more time.

He watches the Duel between Yusei and Roman with Yusei winning. He watches in horror as Roman blows up the bridge and drops Yusei into the Ener-D Reactor. Leo at first believes that he is dead, but, like everyone else there, is surprised when Yusei returns, though unconscious. And after he wakes up and that everyone eventually go up through the same stairs they use before, they all notice in the distant the purple sparks, to which they can only believe means that Jack has won and also activated the third Tower.

Knowing that the last Tower to be activated is Akiza's task, Leo, Luna, Trudge, and Yusei all go to where it is. Arriving at and old and abandoned carnival the twins began looking for her and Mina. After Sayer awakens Akiza's power and is transformed once again into the Black Rose, they notice the tornado that has materialized after she summons "Black Rose Dragon". As they then get to the area where the Duel is taking place, they both notice Akiza's powers having once again manifested even stronger. After Mina and Trudge arrive, they all watch the outcome of the match, with Akiza emerging victorious. However they notice that it's too late for the last Tower to be activated, as the sun has already set.

They then see the Condor geoglyph that has appeared on the sky. The King of the Netherworld not only revives, but also is heading towards the formed Condor geoglyph, which is over New Domino City. However, the Crimson Dragon appears once again to take everyone to Rex Goodwin's mansion. Where he reveals to them his identity as the final Dark Signer and then declares that a Shadow Turbo Duel will be held within Condor geoglyph as a ritual to welcome the King of the Netherworld.

As Yusei, Jack, and Crow accept the Duel in order to stop the resurrection of the King of the Netherworld, Leo cheers for them along with his sister and the rest of the people who can only support them by watching while hoping they win.

World Racing Grand PrixEdit

Leo has enlisted into the New Domino City Duel Academy along with Luna. Dexter also accompanies them as the 3 of them are pupils there of Miss Bartlet. Long after that Leo, Luna, and Dexter go to a haunted forest were people are reported to disappear.

The screen pans away from the house.Luna"explore the forest. A black bird flys. Creeped out, Leo suggests that they turn back. Dexter points out that it was Leo's idea to explore in the first place. Pulling a crafty face, he asks if Leo is scared. Leo says he's not scared, but right after yells, and then points his fingers to Luna saying he was just thinking about

whether or not Luna is scared. Luna simply says she's fine. Leo then says is that so, and continiues saying then so is he. The group proceed, with Leo still a bit scared and holding onto Dexters back as they walk. Luna however stops (while the others walk ahead, having not seen her stop). Luna says while looking at a different direction "This atmoshere...there's something here." Suddendly Luna's eyes turn yellow as she enters a trance, and walks in the direction,

while Leo and Dexter continue to walk ahead. As Luna does, an image of Kuribon appears, as it tries to tell her something urgent. Shortly after, an image of Regulus appears telling Luna that he can feel a strong spirit, and suggests that she turns back. An unseen force then causes the image of Kuribon and Regulus to disappear as Luna keeps walking

(in the dub version after Regulus's image disappears, Regulus can be heard calling Luna's name

Luna steps on a twig, causing her eyes to return to normal. Luna begins to wonder where she is. Luna calls out Leo, and then Dexters name. A creepy noise is then heard which

get's Luna alertive, and she says that she knew it, and that something is here. Suddendly vines begin to come down and surround her. Luna get's scared and calls Leo's name, and

then closes her eyes saying for him to help her then vines warp themslefs around luna arms legs tightly she sutggle but it unless the vines soon gag luna,s mouth then Almost right after, a "Heavy Storm" Spell Card is seen, which activates and destroys the vines around Luna. voice then calls "Are you alright?". The smoke clears, revealing Haley who asks if she's hurt. Luna says no he's, while

finishes by saying his name is Haley, and then says she's. She answers saying her name is Luna. Haley says It's nice to meet her, and continues saying but It's dangerous being

alone, and finishes saying there are lots of bad guys in the forest. Luna says/asks bad guys, while Haley remembers something and asks her to come to his house. He says

Claire will be happy to have visitor, and that Luna will be safe. Luna is surprised to hear there is a house out here in a place like this Leo is running through the forest calling out Luna's name. After stopping he calls out her name again. A creepy noise is then heard, which he get's a bit scared and wonders what it was. Leo calms himself down thinking don't be scared, and that he has to hurry up and find

Luna. Leo then keeps running calling out Luna's name leo then here,s something Suddendly vines begin to come down and surround him then the vines warp them slefs around leo,s arms and legs leo stuggle but it unless he call out for some one to hlep him but soon has mouth is gagged with vines and leo kick off has shoes and slip has socks off

then back with luna and haley

, Haley then senses something and goes over to his window, while Luna asks what's wrong. Haley says something is coming, and that It's a bad guy. Haley tells Luna to stay here with Claire and don't leave the room as he leaves. Luna says wait and she will go too, but is cut off by the door mysteriously shutting, which shocks her

Leo arrives at the house, and says it looks like a big house, and finishes saying it couldn't be that Luna is in there. Suddendly the doors to the house open up with so much force, the wind causes Leo to cover his eyes for a secend. Leo uncovers his eyes and asks what is this.

Haley points at him saying "Your a bad guy, I won't let you take another step here!". Haley readies his Duel Disk, and tells Leo to come duel him. Leo is a bit confused from Haley calling him a bad guy. Luna, who is in the house goes over to the window and opens the curtains, and says Leo's name having spotted him. Leo asks what Haley is talking about, but

stops when he hears Luna say/yell his name. Looking up at the window on the top floor of the house he notices Luna. Leo says her name and runs forward towards the house, but the doors close (Haley is still standing in-front of Leo). Haley tells Leo he told him he won't let him

through. Leo asks if Haley was the one who took Luna, and continues asking why is he doing such a thing. Haley remains silent. Leo takes out his Duel Disk from his academy back pack saying "I'll definitly take Luna back!" Luna walks over to the bed Claire is in and tells her her brother is (Luna stops after opening the curtains realizing It's just a doll). Leo's cards shuffle in his Duel Disk. Both pick up five cards and say duel. Leo looks at Luna, who is watching from the window and says "Luna...I'll definitely save you!". Luna mutters

Leo's name. The duel starts off with Haley beggining his turn and draws. Haley activates the continiues Spell Card "Circle of Life" (yellow circle appears on the field). Haley walks onto it and explains they can't use any Spell Cards unless they discard a Spell card during their turns, surprising Leo. Haley says "Let me show you my combo." Haley sends "Mirror Prison" to

the graveyard, and activates the continues Spell card "Circle of Terror"(a second circle appears on the oustide of the yellow one). Haley explains now they can't summon monsters unless they discard a monster card from their hand during their turns (a dark/black aura surrounds the house Luna is in).

Leo thinks to himself wondering if trapping Luna in there is part of Haleys powers. Leo continues to think while looking at his hand saying now he can't do anything unless he discards cards from his hand. Haley looks at his hand, which contains "Sleepy Beauty","Hollow Spirit", and "Hollow Ghost". He then sends the Zombie-type monster Sleeping Beauty to the

graveyard to activate It's effect. Haley explains as long as Sleeping Beauty is in the graveyard, the Zombie-type monsters in his hand have their Levels reduced by 1. He finishes saying therefore his level 5 Hollow Spirit becomes level 4, and can be normal summoned. Haley normal summons it, and it is revealed to have 1200 ATK. Haley tells Leo that attacks can't be

declared on his first turn, but he will have him take Hollow Spirit's effect. Haley explains that when there's a Zombie-type monster in the graveyard, he can inflict 800 points of damage to the opponent. Hollow Spirit forms blue energys of light that appear to be sucked out of Leo, who's Life Points go from 4000 to 3200, and he yells in pain from the attack. Haley ends his turn.

Leo steps forward a bit, and asks weakly what was that, and it felt like an actual shock. He wonders if Haley is a Psychic duelist. Luna who is watching looks worried. Leo however shakes his head, and thinks to himself saying "Get a hold of yourself, if I get scared of something like this, I can't save Luna!" Leo begins his turn and draws "Morphtronic Scopen". Leo thinks

to himself saying he needs to break this combo, or else. Leo then sends Morphtronic Datatron to the graveyard. Haley however says but there's no meaning in just summoning a monster to break this combo. Haley further explains that Mirror Prison he just sent to the graveyard, prevents most monsters from attacking, although Zombie and Machine-type monsters are safe. Leo

smirks saying then that means it won't have any effect on his deck, and summons the level 3 tuner Morphtronic Scopen in attack mode, which it has 800 ATK. Haley is surprised Leo has a machine deck. Leo says that's right, and continues saying he special summons the level 4

normal "Morphtronic Videon" through Morphtronic Scopens effect. Leo places the monster on his monster zone. Once it appears on the field, it is revealed to have 1000 ATK. Leo then tunes the level 4 Morphtronic Videon with the level 3 Morphronic Scopen. As the monsters fly up Leo chants "Docking strength with courage in order to protect world peace! Syncro summon! The envoy of love and justic, Power Tool Dragon!" (in the dub version Leo says

as he tunes his monsters "A beast with some major motor, a beast made out of pure bronze, here he is, the Power Tool Dragon!")."Power Tool Dragon" appears, having 2300 ATK. Haley tells Leo he is quite lucky, and continues to tell Leo but he won't lose to something without a soul. Leo says don't make a fool of Power Tool Dragon and activates It's effect. Leo explains he

adds one random equip spell to his hand (the deck shuffles as he says this, and he draws "Break Draw"). Leo discards Morphtronic Cord from his hand to the graveyard, and equips Power Tool Dragon with "Break! Draw!". A blue/yellow light goes into Power Tool Dragon. Suddenly a Duel Runner can be heard, which causes both Leo and Haley to look in the direction

the noise is coming from (the wheel part of it is briefly seen for a second). A red Duel Runner comes forward, revealing Yusei. Yusei stops next to Leo and asks him if he's okay, to which Leo happily says his name. Haley says another bad guy has appeared. Yusei realizes something about the duel field, but Leo cuts him off saying he's fine so go rescue Luna. Leo points at the window saying she is trapped up there. Yusei says Luna's name worried, but looks

at Haley. Haley tells Yusei he won't let him take a step into the house. A dark aura begins to surround Haley, making Yusei gasp a bit. Leo steps in saying Haley will be his opponent, and commands Power Tool Dragon to attack Hollow Spirit, and then says "Crafty Break!". Power Tool Dragon hits Hollow ghost, destroying it, causing Haleys Life Points to go from 4000 to

2900. Yusei notices Haley let his guard down, and seizes the chance by driving his Duel Runner towards Haleys house, which Haley get's out of the way. Yusei breaks the doors down as he drives inside and stops. Yusei calls out Luna's name, which she responds by saying his name and turning away from the window. Haley looks mad, but Leo interuppts saying when Power Tool

Dragon destroys an opponents monster, he draws one card. Leo draws "Morphtronic Impact Return". Haley get's angry and says "Unforgivable...I won't forgive anyone who hurts my most precious person!". An evil demonic dark skull envelopes and surrounds Haley, as Leo yells. Yusei having heard Leo's scream says his name, and then focuses on the picture hanging on the wall in-front of him (he also got off His Duel Runner at this point). Yusei says this is, and
continues saying a long time ago, there were some people living in the forest, among them there were two siblings. Yusei continues saying a brother was taking care of his sisters illness, but it made him sick , and the brother passed away, and then it looks like she

(Claire) followed her brothers path as well. Back with Haley; the darkness continues to surround him, and Leo wonders/says "It couldn't be that he himself is a demon?!". Leo says in that case he can't lose, and that he won't hand

Luna over to a demon. Haley explains when Hollow Spirit is sent to the graveyard, another door to the graveyard opens, and finishes saying "Show yourself, Hollow Ghost!". A darkness appears on the ground as Hollow ghost appears out of the ground, revealing to have 2600 ATK. Leo is shocked to see it has 2600 ATK, and finishes saying just when he had defeated the Hollow

Spirit. Leo calms down, and mentally says find a way to beat this guy. Luna says Leo's name worried, The duel between Leo and Haley continues, as Leo looks at "Morphtronic Impact Return". Leo sets it face-down in his Spell/Trap card zone, and ends his turn. Haley tells Leo "Even if you try to take my sisters life, It's ussless! I will protect my little sister

Claire...even if I have to give up my own life!". This surprises Leo to hear Haley say little sister. Haley begins his turn, and draws. He commands Hollow Ghost to attack Power Tool Dragon. A darkness-like blast hits Leo's monster, as Leo's Life Points drop from 3200 to 2900. Leo sends Break Draw to the graveyard in order to negate Power Tool Dragons destruction (the aura surrounding Power Tool Dragon vanishes).

Haley then activates Hollow Ghost's effect, explaining when a card is sent to the Graveyard, 600 points of damage are inflicted to the opposing player. Hollow Ghost flys around Leo, as a blue energy is sucked out of Leo who yells from the pain, and who's Life Points go from 2900 to 2300. Haley says next through Circle of Life, and Circle of

Terror's effect, he sends two cards, a Spell, and a monster card to the graveyard. He finishes saying he will have Leo take 1200 points of damage through Hollow Ghost's effect. Leo continues to yell as Hollow Ghost sucks more blue energy out of him, and his Life Points drop from 2300 to 1100

Haley says he will now end his turn. Leo huffs, a bit tired from the attacks, and says he sees Haley was trying to protect his sister. Leo tells Haley he completely understands

those feelings, and says that's why he definitely can't lose. Leo thinks to himself saying "Luna is an irreplaceable sister to me

one way or another, I'm going to win this duel"). Leo begins his turn, and draws "Morphtronic Datatron". He observes his field saying if this circles powers are what's trapping Luna, then. Leo immediately reveals his face-down Trap card, Morphtronic Impact return. He explains by returning a Morphtronic from his hand to his deck, he can

return Circle of Life, and Circle of Terror to Haley's hand. This shocks Haley as the cards go back to his hand. The circles disappear, and the darkness that surrounded the house vanishes.

Haley get's angry, but then says since a card was sent to the graveyard, he will have Leo take Hollow Ghost's effect. Hollow Ghost sucks more blue energy out of Leo who yells from the pain, as his Life Points go from 1100 to 500. Leo huffs, a lot looking more tired Leo however activates Power Tool

Dragon's effect to add a random equip spell from the deck to his hand. As Leo is about to look at the card, he says "Come to me...the power needed to protect my most precious one!". Leo smiles as he drew what he needed. He plays the equip spell "Power Pickaxe" and equips it to Power Tool Dragon. Leo explains that through Power Pickaxe's effect, he removes one monster from Haley's graveyard that has a lower level then Power Tool Dragon (after Leo says this, a giant scyth is formed on Power Tool Dragon's arm). Leo choses to remove Hollow Spirit. He also states that when Hollow spirit is not in Haleys

graveyard, Hollow Ghost's attack points go to 0. Leo finishes by saying Power Tool Dragon's attack points are then raised by half the removed from play monsters ATK (Power Tool Dragons ATK goes from 2300 to 2900). Leo commands Power Tool Dragon to attack Hollow Ghost, and finishes saying "Crafty Break!". Power Tool Dragon slices

Hollow Ghost in half, which it is destroyed, however haley has revels has face down trap card ghost sotp witch lowed damaged of the attack so haley life points droop to 500 leo ends has turn then haley draws and play pot if gred to draw two card then he play hollow reteun to bring back Circle of Terror leo say what not that agian then haley

When Lester enters Duel Academy, Leo gets very suspicious about him and tries to protect his sister from him. Lester does all he can so he can keep him separated from Luna. While stuck at school, later knowing it was a trick, he sets out to find Lester's mansion and discovers he Duels using a skateboard for riding Duels. After finding this out he asks Yusei to construct a similar device in order to challenge Lester. Yusei constructs a Dueling skateboard dubbed a Duel Board for Leo. He tries to gain some experience riding it, though he has difficulty at first. He then meets up with his sister, who is also trying to practice with the board Lester gave her. However, the skateboard Luna receives is controlled by Lester and forces her to Duel him. Leo then joins the Duel to protect his sister.

During the Duel, Leo identifies the mysterious Duelist as Lester. Luna quickly summons "Ancient Fairy Dragon", but loses it to "Machine Emperor Skiel Infinity" and things begin looking grim. Leo summons "Power Tool Dragon" to try and turn the Duel around, but Lester upgrades "Skiel Attack" and its ability attacks him directly. Despite the fact that Leo could not defeat Lester, Leo did succeed in making Lester so mad that he rushed to finish the Duel without capturing Luna's "Ancient Fairy Dragon", his likely goal all along. Leo is blown off the track and falls, only to be saved by the Crimson Dragon. The Dragon's sudden appearance surprises everyone, even their mysterious spectators. After the Duel, the twins backtrack where Lester lived, only to find an empty space. No one else in Duel Academy seems to recall him either. Despite the fact that the Duel was one in which damage was real, Lester brushed off Luna's attack, but for some reason Leo seemed able to hurt Lester (it is not known why though).

Leo appears during the beginning of the WRGP as a part of Team 5D's pit crew.

During Yusei's Duel with Aporia, Leo, along with the rest of the team, is shown a vision of the future, which leaves him in disbelief, but not to the point where he gives up on the future they're creating. After hearing from Sherry LeBlanc that Yusei will die if he enters Divine Temple, Leo breaks down into tears, questioning if it's really worth it for Yusei to risk his life. He then cries out that he doesn't want Yusei to die, but Yusei reassures the boy that he won't.

Ark CradleEdit

5Dx142 New Signer Lua Leo's rebirth as a Signer, bearing the Heart of the Crimson Dragon

Leo and everyone else on the team accompany Yusei to Divine Temple. After they are split into three groups due to Z-one's trickery, Leo travels with Luna and Jack to the center of the structure unaware that Aporia would be waiting for them at the second gear fully repaired. He is then forced into a 3 on 1 Duel with Jack and Luna with their life on the line. Despite his attempts to power up "Red Dragon Archfiend" and protect Luna's Life Points, his strategy backfires after Aporia Summons "Machine Imperial Soldier Grannel Ein" and knocks out both of his partners, destroying Jack's Ace monster. Aporia then declares by the current situation that Leo would have to continue alone against him after he ends his turn. Leo, in his efforts to protect Luna, manages to Special Summon "Power Tool Dragon" and "Ancient Fairy Dragon" which, ultimately, leads to his death. However, he is revived due to the effect of his "Morphtronic Lantron" and the power of the Crimson Dragon, obtaining the Heart Mark of the Dragon, making him the sixth Signer. Finally he Synchro Summons "Life Stream Dragon", and is able to restore Luna's, Jack's, and his own life points due to its effect (their wounds were also healed, but it is currently unknown why). When he attacks Aporia during this turn, it marks the only time in the Duel that Aporia appeared to be physically affected by taking damage (for unexplained reasons). They finally defeat Aporia by reducing Aporia's strongest monster's ATK. After meeting up with the whole team, they venture deeper into Divine Temple and finally find it's main inhabitant. The team is surprised when Aporia who was presumed dead reappears and initiates a Duel with Z-one, aiming to remind him of hope. Even though he manages to summon the three Meklord Emperors, they are of no use against Z-one's Time Lords and eventually he is defeated. Realizing the power of Z-one's Deck, and following the example of Jack, Crow and Akiza, along with his sister, Leo gives Yusei his "Power Tool Dragon" and his "Life Stream Dragon", hoping to aid him in the last battle.

Team 5D's futureEdit

Ruariding Leo as a Turbo Duel champion in the future.

About half a year after the battle with Z-one, the twins receive a letter from their parents. In it, they tell them that they want to live together, but for that to happen, they may have to leave New Domino City. Leo and his sister are unable to decide what to do because they want to stay with the gang. After Jack challenges Yusei to a Duel which he agrees, the twins along with Akiza and Crow watch the Duel. They ultimately decide to go with their parents, and years later, Leo would become a professional Turbo Duelist.



5Dx043 Luna needs Leo Leo and his twin sister Luna sharing an emotional moment together

Leo and his sister are known to be together in almost every scene of the show (not included in the Fortune Cup) and have an extremely close bond. Throughout the entire show, it is made apparent that in every situation involving Luna, Leo is the one to give her the strength to fight back.[11][12][8][7]. Luna is the most important person in his life and he will protect her at any cost from dangers; to Luna, Leo is her 'hero' and she can't live without him.[12] It is a known fact that Leo and Luna go together to Duel Academy along with Dexter and their teacher Miss Bartlet.[13] Even though the twins have their ups and downs they love each other dearly and are considered the most valuable person in the other's life.[12][4][4] When they were battling Devack and his Earthbound Immortal he said he wanted to show that he can protect his sister from harms way including from Devack and Luna tells Devack she will never forgive him hurting the person she cares about most in the whole world.[12] He also feels that he is useless and can't protect her from harm but Luna says she needs him. In the original he said he use to think Luna was a pest, while in the dub he said he thought she had been holding him back.[14] In the Duel with Aporia, after Luna got knocked out from Machine Imperial Soldier Grannel Ein, it had a devastating effect on him similar to the first of Aporia's embodiment of despair Lester had his parents lost. This Duel further affects him in his confidence of protecting Luna, while at several parts of the Duel Aporia counters all of Leo's moves leaving both Jack and Luna close to death.[15] This makes him to force himself to be stronger and literally put his life at risk to protect Luna, best demonstrated by using Double Ripple to summon Ancient Fairy Dragon for Luna, which costs him his life (for a brief moment) and was reborn as the Sixth Signer with Life Stream Dragon.[6][7]

5Dx152 She's your sister Leo blushing, and getting flustered at Luna's new look.

Leo has shown strong protectiveness and jealousy when someone flirts with his sister, or when she shows romantic interest in someone (particularly in the Japanese version).[8] After the fight with Z-one, Leo blushes upon seeing Luna in new clothes, commenting on them while turning away and smiling (and being noticeably flustered).[16]

Yusei FudoEdit

Yusei Fudo is shown to be like a brother-figure to both Leo and Luna. Leo is shown to look up to Yusei as the best Duelist ever. Yusei has given Leo many tips when it comes to Dueling and has inspired Leo to become even better. This is seen after Leo faces against Devack, to which during the Duel Yusei notices that Leo is Dueling more carefully, realizing that he has changed and grown up since their first Duel.[17] Because of this, after the Duel ends, Yusei congratulates and tells Leo that he did well.[18]

Jack AtlasEdit

In episode 13, Leo is shown to admire Jack Atlas from the time the latter reigned as King. He has figurines of Jack and his "Red Dragon Archfiend", but now thinks of Yusei as the better Duelist after the Fortune Cup, much to Jack's annoyance. Even if he does, Leo was inspired by Jack to become a great Duelist. During the Duel against Aporia, Jack notices something new about Leo and said that Leo would protect anyone at any cost even if it means giving up his life.[7] Although not seen too much, Jack has shown concern for Leo, like a surrogate father/older brother to him, and tells Leo to never give up fighting (which occurs when Aporia tries to get Leo to give up, and when Leo dies from Aporia's attack for a moment).[6]

Akiza IzinskiEdit

Leo looks up to Akiza Izinski as a Duelist, even when she went under her alias, the "Black Rose". Although he was somewhat scared of her, he still admired her abilities. He wants to be ranked at the top of his class like she is. He also relied on her to stand up for their right to Duel in Duel Academy.[13] He often refers to her as "Big Sister Aki", and has great respect and love for her like a sibling. (Japanese version only).[19][20]

Bob and DexterEdit

Bob and Dexter are Leo's friends, as he is seen to hang out with them at Duel academy (and has known Dexter before he met Yusei).[13][8][21]


Like the other members of team 5D's, he saw Aporia as an enemy. During the Duel in the Ark Cradle, Aporia constantly caused Leo to feel despair by attacking Jack and Luna, but instead, Leo responded by fighting bravely and died for a moment, but then was revived as a Signer, and with Jack and Luna, he shows Aporia hope.[6][7] During Aporia's Duel against Z-one, Leo showed respect towards Aporia and was constantly worried when he got hurt. When Aporia died, Leo was shown to be sadder than anyone else, then he angrily yelled at Z-one for killing him. Before Aporia Dueled Z-one he told Leo that he saw the hope that he possessed within him, and that hope was the very same that Aporia had been seeking
