Rewind

 is a gay character from Generation One of the IDW Transformers comics. He is married to Chromedome and was previously married to Dominus Ambus.

He is an Autobot and an archivist. His small stature makes him a minibot. He met Chromedome while the other mech was waiting in line to die in a suicide clinic during a particular dark period of the Cybertronian civil war. Rewind was there looking for proof of death of his previous husband (or other information pertaining to him), and Chromedome decided he would rather assist this spirited mech than die that day.
