For other uses, see: Ghost (disambiguation).

Ghost is a Riding Roid in Yu-Gi-Oh! 5D's.

History
After it was discovered that Ghost was responsible for the reported Duel Runner crashes and the major injuries incurred by several defeated duelists, as the damage caused by each duel was real, Trudge investigates and asks for Yusei's cooperation. He faces against Trudge in a Turbo Duel, in which he Summons "Machine Emperor Wisel Infinity" to defeat him.

During the duel, Ghost tells Yusei that Wisel Infinity exists to remove the unnecessary things in the world. Ghost, referring to Synchro Monsters (which he believes are not needed in the world), states that this monster is the "proof of human´s evolution."

After he is defeated in an intense Duel by Yusei, Ghost ends up exiting the duel lane and crashing down into some trees. Before Yusei, Jack and Crow arrive, Placido appears to take a fragment of the Duel Runner along with his Deck. Yusei, Jack and Crow rush down afterwards and discover that Ghost is a robot.

Trudge then later reveals that this special robot was being used by Sector Security in order to assist them with crimes involving Duel Runners. Also this robot had been the prototype that went missing a few days ago.

There was no information on the Turbo Duel chip regarding all of the current events, as all the data was programmed to be erased once the robot lost the Duel.

After Team Catastrophe is defeated by Team 5D's, Placido lets loose an army of Ghost Riding Roids. He refers to this army as "Diablo".

Deck
The deck Ghost uses, owned by Placido and used by Ghost for testing purposes, is an Anti-Synchro deck based around Machine Emperor Wisel Infinity and its various support cards. He uses a multitude of Trap cards to easily Special Summon the parts of Wisel Infinity and maintain control of the field. Later when Placido unleashes a whole horde of Ghosts to defeat every duelist in a Battle Royal, they all use Allies of Justice to swarm the field and deafeat all their opponent almost immediately.
