Chromedome

 is a gay character from the Generation One IDW Transformers comics. He is married to Rewind.

Chromedome is an Aubotbot and a skilled mnemosurgeon. He met Rewind while 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.
