Robo-rat

Robo-rats (possibly synonymous with retrorats but different to glitch mice) are small Cybertronic creatures resembling Earth rodents, if not ecologically than at least linguistically, insofar as one might rhetorically invoke them if an explosion were to interfere with one's probe. Sea Change

They may be inhabitants of Slaughter City. The Hunting Party

Notes

Not to be confused with RAAT.

• A Cybertronic rat creature appears in the Marvel UK story "The Hunting Party". It is not given any designation, but since it's a rat on Cybertron, it might be a robo-rat.
