Travis

"Brother Travis" in The Space Adventures of Little Gay Longcat isn't meant to be Travis from Blakes 7, he's a canon* character from the early days of Warhammer 40,000. Here is the original Brother Travis from the Spacewar set of Citadel Combat Cards (c.1988):

Ooh, he is a strong manny with a Strength of 10. And with his metal eye he does look a bit like Travis from Blakes 7.

Oh wait, it's the wrong eye.

*LOL. As if 'canon' in Warhammer 40,000 ever counts for anything.
