Created by Professor Hackle, this purple robot was a much larger version of Cybertron. After Cybertron was greatly damaged, Hackle was ready to loan this prototype to the SWAT Kats. They hastily declined.
The arch-nemesis of the SWAT Kats, Dark Kat is a villain that terrorized Megakat City long before the vigilante duo even formed. His actual identity remains a mystery, but his intentions of destroying the Enforcers along with Megakat City and its government and rebuilding a new “Dark Kat City” from the ashes that would be under his rule are well known.
