Jumpstarter


 * The Jumpstarters are an Autobot subgroup in the Generation 1 continuity family.

The Jumpstarters Topspin and Twin Twist are impulsive warriors with the ability to transform very quickly between modes.

Toys
Both Jumpstarters are notable for their autotransforming feature. Their alternate modes are spring-loaded, and held into place by a catch. Equipped with [[pull-back motor]s, they race forward when released, tripping the catch, which allows internal springs to snap the robots' bulky legs into place, which are balanced so as to leave the robot standing upright on its rather broad feet.

On both figures' back is a device resembling a switch, which actually controls the position of a small internal weight. If a Jumpstarter won't stand upright when its legs snap out, but falls over sideways, the switch can be moved to the other side to compensate.

Jumpstarters were made in sufficient numbers to fill the toy boxes of the entire known universe.
