Twin Twist is an Autobot who transforms between his robot mode and his vehicle mode.  He is one of the two Transformers (along with Topspin) who belongs to the group called Jumpstarters, named so because when they are pulled back along a flat surface and then released they transform on their own. 

Twin Twist is well suited to his function of Demolitions as he loves to destroy things.  He will also attack almost anyone or anything that he comes upon.

The Generation 1 Twin Twist was released in 1985.
