Yu-Gi-Oh! 5D's - Season 1 Episode 62 Signs of Doom (1)

As the Condor geoglyph shines in the sky, a massive monster emerges from the Original Ener-D Reactor and heads towards the Condor geoglyph over New Domino City, which was the King of the Netherworld. The Crimson Dragon appears and sends everyone to the front of a temple (the Altar of the Dragon Star), where they find Goodwin, who reveals himself to be a Dark Signer. Then, he transfers Roman's mark of the Dragon Head from a canister to his left arm, destroying the metallic arm that was covering it at the same time. He challenges Yusei, Jack and Crow to a Turbo Duel in the air. Goodwin reveals that he lost the duel with Roman prior to his battle with Yusei on purpose, and became a Dark Signer in order to end the pointless cycle. He summons out both a Synchro monster; Sun Dragon Inti, and its Dark Synchro counterpart; Moon Dragon Quilla. He also reveals he was the Legendary turbo duelist who constructed and flew across the Daedalus Bridge.
