Carl

Security Officer Carl was responsible for stopping internal threats to the Dread Cruiser.

Appearance
Carl's only appearance was in the episode Holopad where he was seen with his head torn out by the Lizard Man.

Misc.

Carl was killed by the Lizard Man when his head and spine were torn out (presumably to be kept as trophies). Based onthe fact that Larry referred to Carl as "buddy" we can infer that the two were friends (or at least knew each other).
