Quickswitch
From Multiversal Omnipedia
Quickswitch was an Autobot six-changer, endowed with six different forms- robot, jet, tank, gun, winged puma, and speedboat. Unfortunately, he also had schizophrenia, his moods changing as often as his forms.

According to commercials for the toy, Quickswitch was the "son" of Sixshot, atoning for his "father's" misdeeds.
