Yu-Gi-Oh! 5D's Ride 22: "Duel Dragons!!"
Leo, known as Rua (
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. Whilst controlled by the miasma of "Power Tool Mecha Dragon", he often displays an evil expression on his face. After his first Duel with Yusei, Leo's face features a bandage as he sustained an injury.
While under the influence of the miasma of "Power Tool Mecha Dragon", Leo is quite sadistic. This is shown when he enjoyed crushing D1 Grand Prix Duelists with his and Luna's Duel Dragons or when he sat back and watched as two bystanders were almost killed by a stray missile fired by his Duel Dragon during a Duel. Although this is said, Leo has a soft side, especially when Luna is involved and he will do anything to help her (as shown with his participation in Turbo Duels in order to raise funds to pay for her medicine). Leo also often gets into arguments with Luna over her teasing him or with Crow Hogan who usually mocks Leo for his size.
In the past, Leo and Luna were left by their parents to fend for themselves. Luna had a serious illness, which required large amounts of extremely expensive medicine to treat. To maintain a constant supply of these medicines, Leo and Luna both delved into the world of underground Turbo Duels in order to obtain the necessary money.
At first, they were a raging success and made large profits, but they were eventually beaten. After the loss, Luna became seriously ill, leaving her brother to Duel by himself. Being alone made Leo's performance significantly worse, causing him to lose even more Duels. Angry fans of his, who had lost money in bets on the outcome of his Duels, ganged up on the boy and dealt him a harsh physical beating. When Leo couldn't take any more, he fell to the floor and cried out, only to look up and see Lazar holding out the "Power Tool Mecha Dragon" card, and offering Leo a place as an eliminator in order to pay for his sister's medicine treatment. Leo accepted the offer and took his place in the D1GP.
During the second round of the D1 Grand Prix, Mina Simington reports to Rex Goodwin that the semi finalists are being attacked by Leo and Luna. Leo boasts about how if he defeats Aria, it'll be his 5th victory that day and that the D1 Grand Prix contestants are weak. Luna agrees with him, stating that they're even weaker than he is. Leo then proceeds to attack Aria, winning. During the assault, one of "Power Tool Mecha Dragon's" screwdriver missles almost kills two bystanders, but Crow intercepts it with his "Blackwing Tamer - Hawk Joe". He then scolds Leo, who says he'll target Crow next. Later on, Goodwin informs the remaining contestants that he's dispatched Leo and Luna in the tournament as only the best should remain.
Leo later appears before Yusei and Crow, the both of them mistake him for Sect but Leo scolds them for getting his identity mixed up with someone else. Crow mocks Leo and his sister, saying that they should be in bed as its late, but Leo mocks Crow back, calling him a "broom-head". Leo then proposes a Duel to Yusei, showing him his Duel Dragon, causing a Shadow Miasma to pulse from the card. Both Crow and Yusei feel it, surprising Luna. Leo also reveals that Godwin is involved with the Duel Dragons to Yusei. During the Duel, Luna tells Leo that if any of her "Forest" archetype monsters are destroyed, she'll make Leo pay. Leo then manages to Synchro Summon his "Power Tool Mecha Dragon".
Leo continues his assault, managing to power up his "Power Tool Mecha Dragon" with his Equip Spell Card strategy. Yusei manages to Synchro Summon "Seven Swords Warrior" in order to conduct an Equip battle with Leo, but his "Duel Dragon" steals Yusei's Equip Spell Cards. Yusei then uses "Sword Dance" which fires several solid vision swords at Leo and Luna, one of which hits Luna. This causes Leo's anger to increase, making the Duel Dragon's Miasma intensify. Leo then fills his entire Field with "Forest" monsters with cards to power up his "Power Tool Mecha Dragon" to 4800 ATK. It then beheads "Seven Swords Warrior", causing Yusei to lose 2500 Life Points with Leo telling Yusei that the Duel belongs to him.
Later, Leo and Luna are shown to have passed to the tournament's second stage. Their first opponent was Tetsu Trudge, but the twins defeated him with ease. Luna even called him weak.
Next, Luna is reading a fairy-tale book. She comments on the book like if it was a real story, and says that she must defeat the "dark wizard". Leo sadly notes how she is acting strange. Goodwin then appears to them as a hologram. He tells them that they must defeat the "dark wizard", and Luna realizes he is Yusei. Leo asks if that will bring Luna back to normal, and Goodwin confirms it. However, Goodwin's plans are only to test Yusei's Duel Dragon's strength, and for that, he needed to use another Duel Dragon. Leo and Luna then go after Yusei.
Leo uses a "Of the Forest"/"Morphtronic" Deck focused on swarm tactics so he can easily Synchro Summon his and Luna's Duel Dragons. The Deck also features a large amount of Equip Spell Cards for "Power Tool Mecha Dragon" and the "Fairy Tale" series for "Ancient Fairy Dragon". Despite lacking "Morphtronic" monsters, Leo uses "Morphtronicize" to transform his monsters into them so he can use their support cards.
