Grif is the cynical loud-mouth of the Reds, being self-centered, immature, acerbic, and lazy. With respect to personality, Grif is fairly brash and has a flair for the melodramatic. He is quick to make silly theories or insults, even toward people who could clearly kill him without hesitation. Grif is also cowardly, easily scared and would rather run away from a battle than deal with it. Although he admits to being lazy, he is lazy because he enjoys how much it irritates Sarge.
