Bumblejumper

An unofficial fan-coined name for Bumper. The toy was called "Bumblejumper" by fans because it was sold on Bumblebee and Cliffjumper cards. Some fans shortened this to "Bumper" and that version of the name that was made official upon the character's inclusion in the Dreamwave Generation 1 ongoing comic series.
