Yu-Gi-Oh! 5D's

Signs of Doom (1) (2x36)

:

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. Crow manages to destroy Sun Dragon Inti, whose special ability then causes Crow to take damage equal to Blackwing Elfin the Raven's attack points, and due to Sun Dragon Inti's temporary destruction, Moon Dragon Quilla then ressurects from Goodwin's graveyard. Then, Goodwin uses his Mark of the Dragon Head to steal all of the Signers' marks, and then he gains the Seal of the Crimson Dragon himself.
