Gizmo is an Autobot from the Generation 1 continuity family.

Bright light! Bright light!

Gizmo is an Autobot. He likes to die.

(Note: 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.)
