The Scales Gang
Formerly members of the Alphonse Mafia, they were attempting to steal a mutagen by exposed to it instead and their DNA combine with that of dinosaurs, turning them into hybrid creatures.
Using their new strength, they took over the Alphonse Mafia and started trying to expand their power.
They all met their end in 1962 when they attempted to steal an experimental submarine. Not knowing that it was nuclear powered, they caused the reactor to become unstable when they boarded it. Golden Shell and Blaze managed to get the vessel to open waters before it exploded and took the Scales Gang, who did not believe the heroes when they warn them, with it.
