The Immobilizer
Wheeljack has created the Immobilizer, a new weapon that can temporarily stop any Transformer in its tracks. The Decepticons manage to steal it partly due to Carly (first appearance) distracting Ironhide from his lookout post. During the battle which follows, Ironhide rescues Carly from the Decepticons, but they have made the Immobilizer's affect permanent and start immobilizing Autobots left and right. With the assistance of Brawn and Jazz, Spike and Carly manage to reverse the effects of the Immobilizer and save the Autobots. The Immobilizer is then destroyed.
