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 symbiote 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.^[1] When they finally attempted to apprehend their target, Coldwar was killed and devoured by the symbiote.^[2]

Coldwar repeatedly suggested to Killer Thrill that they capture the symbiote they had been hired to apprehend as quickly and efficiently as possible, revealing himself to be a pragmatic individual.^[3]
