Guy Gagné was shown being watched on an old Garage TV showing a recording of the Indy 500 and Theo (also known as Turbo), a snail pretending to be an IndyCar racer, looked up to him as his idol. Turbo dreamed he was fast and was granted the power to race.
Later, before he first saw Turbo beating his record, a Taco Man named Tito showed Turbo as the next Indy 500 champion.
Turbo meets up with Gagné and tells him he believes in him. However, Gagné reveals his true colors when he tells our hero that dreamers have to wake up and plots to take out Turbo in the Indy 500.
Later at the race, Turbo was about to race and Gagné prepares to beat Turbo. During the final lap, the villain was about to step on Turbo and crush him. However, the speedy snail made his way to the finish line when Gagné attempts to step on him. Gagné was later beaten up by Kim Ly for trying to kill Turbo. The rest of Gagné's fate was unclear, but the news paper showed him now as the former champion, shamed and being forced to face many Indycar sanctions, costing him his fame and most likely his car.
Guy Gagné comes across as an eccentric yet charismatic charmer but, he's really a competitive egomaniac who will anything to win. He's all speed with no heart at all.
