A robot shaped like a blue insectoid alien, Coldwar, alongside fellow bounty hunters Killer Thrill and Guzz, was hired to capture a particular klyntar that had made its way to Earth. His advice that they move to capture the klyntar while it was in a weakened state were repeatedly vetoed by the eccentric and maniacal Killer Thrill, who wanted to observe the symbiote's activities after it acquired a superhuman host. When they finally attempted to apprehend their target, Coldwar was killed and devoured by the symbiote.
Coldwar repeatedly suggested to Killer Thrill that they capture the Klyntar they had been hired to apprehend as quickly and efficiently as possible, revealing himself to be a pragmatic individual.
