Punch


 * Counterpunch is a Decepticon in the Generation 1 continuity family. His Autobot counterpart, Punch, is close.  Real close.

Punch is an Autobot, but he pretends to be a Decepticon named Counterpunch. Both of him are really secretive.

Animated continuity
When they arrived to steal the key to the Plasma Energy Chamber, Counterpunch warned Pounce and Wingspan about his own impending attack, making a big deal about how Punch was his "Autobot counterpart."

Genius, I tell you.

Generation 1

 * Punch/Counterpunch (1987)
 * Punch transforms into a blue sports car. He has two distinct robot modes, with separate guns and rubsigns for each.  They have separate arms, but the backs of Punch's torso, legs, and even head are the fronts of Counterpunch's and vice versa.  The top of their shared head tilts to disguise the face not currently being used.
