|Anime debut||Yu-Gi-Oh! 5D's episode 113: "Burning, Seething Soul! Scar-Red Nova Dragon"|
The Legendary Signer was a Signer, who lived ten millennia before the battle with the Dark Signers featured in Yu-Gi-Oh! 5D's. He possessed the full Mark of the Dragon on the left of his chest and wielded the Blazing Soul ability.
Battle with the Crimson Devil
The Signer came forward from the ashes of a volcano and performed a miracle. He was able to absorb the Crimson Dragon's power, through Blazing Soul, and used it to defeat and seal the Crimson Devil.
When Jack Atlas faced the Crimson Devil's servant, the Familiar of Red Nova, he spoke of Blazing Soul, which reminded Greiger of the Legendary Signer. Using Burning Soul, Jack absorbed the power of the Crimson Devil and created the card "Red Nova Dragon", which he used to defeat the Familiar.
