Stopgap is a highly-trained member of the elite Maximal Command Security Force. His job is to uphold the will of the Maximal Imperium on Cybertron in the name of the Pax Cybertronia. Having honed his skills as a private investigator, forensic scientist and crime scene investigator on the planet Edaps, Stopgap can find out a lot about a crime with even the scantest of clues. However, he tends to get so wrapped up in his own work that he unintentionally ignores things that are happening around him. 
- Stopgap — like all of the MCSF — uses the Cybertron-series Clocker toy as a base (with a modified Machine Wars Skywarp/Thundercracker head), though no official Stopgap toy exists (and probably never will). His color scheme is based somewhat loosely on the Beast Wars II Maximal Diver.
