I never really questioned it before, but does that last image have any correlation to this story? Besides having the "new guy" on there, of course.
Ah so the goats in the chaos team of Blood Bowl can mutate as they level up, extra arms, heads, tentacles etc. Then there’s the 4 chaos gods, so made a different version for each god. You can’t choose a god in the game, but there is a Khorne and a Nurgle team. Thinking he would end up like one of these when he “plays” in the team. Or maybe they actually let him play hehe, dunno.
Aaw yeah, didn’t think it trough that much but yeah the “new guy” probably has seen mutated players before and wants to transform. Though I’d like to think that the “new guy” is special, the usual goats look like the guy on the left in the 7th pic. So the goats in the last pic would be how this specific goat would look like mutated.
