Description: Apparently your best friend has some huge temper issues and your biggest rivel could have eaten you had you not become what you have become. Satan likes to lick himself too.
the zerg/infested Kerrigan could have devoured raynor easily had he not become some kind of ox-necked musclebeast with a country accent, and had he not gone from wearing a space suit to wearing a giant mech suit.
Tychus has temper tantrums.
Diablo is actually a run of the mill infested terran. They have multiple huge tongues for some reason and enjoy licking themselves.
