Metaboss is a brawny, unintelligent, anthropomorphic pig-like creature in Mario & Luigi: Bowser's Inside Story. In lieu of working to conquer his own kingdom, he is a minion of Fawful who robotized and was tasked with guarding Bowser's Castle, as well as fighting Bowser three times. Akin to his master's tendency to speak in Engrish, Midbus speaks in broken sentences that make little sense, and gives unnecessarily long names to various weapons that he uses. Given his physical similarities to Bowser, he may have been created as a foil to the Koopa King. He is also shown to be able to survive fire as shown when Bowser's breathed fire on him when fighting his Castle.
