Basically a parody of Digimon Hunters and Transformers Beast Hunters. Vector Prime as the Watchmaker for obvious reasons, Whirl as Clockmon for a less obvious reason (for a time he was a skilled clockmaker in the IDW canon). Tagiru is represented by a young version of Overhaul from Cybertron. His Arms Micron is Liger Jack (the JP name of Leobreaker) who represents Gumdramon. Probably looks like him to some degree with a dash of Lio Junior.
Overhaul’s Beast Armor is based on Leobreaker and Lio Convoy.
