Old one-eye

Old one-eye is a carnifex from an old Tyrannid swarm that had his eye blown out by a bolter round. The reason why Old one-eye is so aggressive is because the Tyrannid fleat that he was in had left him, and he has no neuro link to the hive. (story) Old one-eye has landed on a mysterious planet with tons of unique and dangerous monsters on it. One day, you(be whatever monster from the monster hunter franchise you want) come across Old one-eye while finding food.
