Martin 2 is a koala bear person from an alien planet that first appeared in "On the Lam." He is the elderly leader of the rebel koala bear people who met and befriended Martin while they were both imprisoned, and even built a sort of father-son relationship with him, until Martin abandoned him after realizing Martin 2 was an adult fully capable of fighting for himself.
