During a dark era of Cybertronian history, Chromedome was partnered with Prowl – one of the most decorated members of the Autobot Police, renowned for being painfully detail-oriented and a stickler for procedure. Chromedome stuck with it however and used this partnership and his position within the police to further his interests in mnemosurgery. The techniques he mastered allow him to search a suspect's mind and secure any information necessary for the case.

Interests soon changed into resentment as he was forced to use his skills, not only for interrogation, but also to reprogram individuals' memories and alter their minds. Over the years, he attempted to his inadvertently nefarious past as well as his ability to reach into others' minds... until he ran into another Autobot obsessed with memories. Rewind was persistent and eventually dug his way into Chromedome's past and in doing so ensured a place in Chromedome's future.
