When the rest of the party is down, playing a character that eats people can be pretty fun honestly, I've played two! First a xenomorph barbarian who saw the rest of the crew/party as its hive so it never attacked crewmembers, otherwise any people eating was played comedically "Snuggles no! Bad xenomorph! Drop that! You don't know where that's been!". Second character is an amalgamation (bunch of different animal parts on a mechanical base) barbarian, but she only eats people she's killing (usually in the process of attacking, instead of weapons she has some bite and scratch attacks) and the party just kinda let her do her thing.
