Carl

Carl (カール Kāru) is a character in the Yu-Gi-Oh! ARC-V anime. He is a participant in the Maiami Championship and is a member of Knight of Duels.

Maiami Championship
Carl and the others Knight of Duels were first seen in the Maiami Championship opening ceremony. In the Center Court, Carl, Ashley and Bram watched their comrade Charles be defeated by Shun Kurosaki. The next day, the 16 participants was in the LDS Center Court, save Shun, whose absence frustrated Carl the other two Knights. They were informed that instead of single Duels, they would be participating in a Battle Royal around the city. At the Ruins Area, they found Shun eager to avenge their friend Charles. But they are easily defeating by Shun's "Rise Falcon" in a single attack. During Yūya and Shun's conversation, the Knights of Duels performed a Battle Royal between themselves with Yūya and Shun at the center launching attacks with their three "Assault Knight Slash" in order to physically harm the duo while keeping themselves alive through its effect. They further provoked them that they were "Dueling" and if they are displeased, they could join their Duel and pay the 2000 LP penalty for intrusion. The attack blew away both Shun and Yūya from each other. They are interrupted by the arrival of Sora Shiun'in and Obelisk Force who Dueled them. Shortly after, the three Knights are defeated by Obelisk Force and turned into cards.

Fifth Dimension ARC-V Arc
After Zarc's defeat and the Standard Dimension being reborn into the "Pendulum Dimension", Carl was freed from his card.
