Crotesius was one of the biggest nerds in Bionicle history. He was a fan of Doctor Who, Harry Potter, Super Heroes Star Wars, Star Trek and Firefly. He would get upset at anyone who insulted any of his fandoms and attack them with a big chainsaw that was made out of items associated with all of his fandoms. He was best friends with Nuju and Piruk. One day he got in an argument with Piruk over which was better, Wolverine or Cyclops. The argument ended when Piruk sliced him to pieces with his claws.
