Gizmo

Gizmo is an Autobot from the Generation 1 continuity family.

Bright light! Bright light!

Gizmo is famous for his, well, gizmos. His best (okay, only) known gizmo is his holomatter projector. He transforms into a little Cybertronic dunebuggy.

He likes to die.

It is unknown whether the two instances of "Gizmo" being a named Autobot are of the same character. As the first was never seen, and both instances are from writer Simon Furman, it's likely —but not definitely proven— the latter instance is a reference to the first, despite the different continuities.

Sometime later, Gizmo was one of the Autobots in Hot Rod's first command, along with Backbeat, Dealer, and Download, assigned on a mission to the Omega Bunker on Ki-Aleta to secure the Magnificence, a mysterious artifact of great power. Gizmo was responsible for setting up his holomatter projector program to disguise their arrival.

Unfortunately, he also received the dubious honor of becoming the first casualty under Hot Rod's first command when the Omega Bunker's guardians destroyed his holoprogram and killed him to death. He wouldn't be the last. Spotlight: Hot Rod

Hot Rod later realised that Dealer was the one who betrayed them and was responsible for their deaths. Spotlight: Doubledealer
