Created by Peter Milligan and artists Brett Ewins and Jim McCarthy, Protoid appears in the 2000AD series Bad Company.
Protoid - a dangerous, evil alien creature who was also a spacecraft. He joined Bad Company under the false pretence that he hates Krool. In reality, he wanted to get close enough to the Krool Heart to replace it.
In the final assault on the Krool Heart, Danny Franks joins with the heart and Protoid is killed by Kano and Franks.
