List of Yu-Gi-Oh! 5D's characters

There are also Dark Signer-like figures (called Shadow Drones in the dub) who are recruited and controlled by Roman's spiders.

In addition, their duels end with the losing duelist being killed (in the dub, the loser is sent to the Netherworld).

Originally led by Goodwin, Yliaster (イリアステル, Iriasuteru, also Iliaster) was an organization of Star Guardians, who are said to bring peace to the world and worship the Crimson Dragon.

Their true purpose, however, is to steer the world to change the future, which was destroyed by Dr Fudo's creation of Ener-D (Momentum in Japanese).

The Fortune Cup is a tournament organized by Rex Goodwin with the purpose of awakening the powers of the Signers.

Along with Yusei, Aki and Leo (disguised as Luna), there are other duelists whose jobs are to put pressure on their opponents in order to awaken their abilities (the exception is Hunter Pace, who replaced one of the combatants in order to beat Yusei).
