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

Notes

Not to be confused with RAAT.

• Per the dialogue script, Starscream was going to say the "Autobots have us trapped like robo-rats!" in "A Decepticon Raider in King Arthur's Court", but the line was dropped as-aired.
• 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.
