When Team C arrived at their new headquarters, they found a loveable peppy dog named Mr. Scraps already in residence. He has an uncanny sense of direction (for finding his way home). After a run-in or two where the dog shrugged off bullets of attackers he appears to be completely indestructible. That causes problems because he doesn't feel much pain, either. Scraps is motivated by snacks, though. The lack of any super-powered canine strength allows those who want to train him to possibly do so if they spend the time.
At headquarters, Mr. Scraps is fed and cleaned up after by Gorak the caveman janitor. Gorak is jealous of this responsibility. Mr. Scraps, however, is ambivalent about Gorak. On the one hand, he likes the food; on the other hand, Gorak just doesn't “smell right.”
