Blister, known as Saiga in the Japanese version, is a character in Yu-Gi-Oh! 5D's. Blister is a proclaimed "Jack-of-all-trades" in New Domino and a friend of Bolt Tanner.
Years before the current storyline, Blister's best friend, Aero, was severely injured in a Duel Runner crash. They were in a tag-team Turbo Duel, with Aero in the side-car. Their opponent spun out and knocked Blister off track, causing the cable connecting the two cars to break. Blister tried to save Aero, but pulled away to avoid crashing. Aero crashed into a factory, while Blister spun away, breaking his Duel Runner. Unbeknownst to Blister, Aero saved "Machina Sniper", which was their favorite card, from a blaze, causing him to get hit by an explosion which could have been avoided otherwise. Although he survived, he was badly burned and never took part in another Turbo Duel. He later sent the "Machina Sniper" card to Blister, a gesture his former friend assumed to be out of spite. This incident caused Blister to develop a grim outlook on Duel Monsters and on friendship in general.
Following Bolt Tanner's instructions, Yusei Fudo seeks Blister's help in recovering his Duel Runner and Deck from Sector Security. Blister ridicules him for planning to sneak into Security's storage facility to steal it back, telling him it's the same as getting caught.
After Yusei assures Blister that Aero has no anger towards Blister after that day, he returns the favor by stalling Trudge after Trudge chases Yusei following Yusei's break-in. Blister manages to avoid capture and later springs Tanner and Yanagi from prison to prepare for the Fortune Cup.
Before the Fortune Cup, Yusei tells Blister of his captured friends from Satellite, which Lazar uses to blackmail him into entering and Blister tells Yusei that he will call in a favor from an old friend to sneak into Satellite and check on them.
He was with the gang when Yusei and Crow were finally reunited. After the Shadow Duel between Yusei and Kalin Kessler, he helped Yusei's friends retrieve Yusei's busted-up Duel Runner by pretending to be a member of Sector Security.
He returns with Yusei and the rest of the Signers when they return to Satellite to take on the Dark Signers and is there to witness the fall of Martha, Yusei's foster mother.
Following the defeat of the Dark Signers as well as Rex Goodwin, Blister meets up with Yusei again when he, Jack and Crow hear about the story of Bashford.
Blister is present with Lazar, as Lazar leaves his family at Martha's refuge.[1]
He is later seen at Martha's orphanage during episode 139, driving a bus he salvaged from a junkyard away from the city in order to avoid the falling Divine Temple. In episode 150, he, Martha, Dr. Schmidt, and all Marha's children are cheering for Yusei.
