Iron Clefts are enemies that appeared in Paper Mario: The Thousand-Year Door. The dreaded Iron Clefts make up the first Major League team in the Glitz Pit. These guys are so powerful, they can't be harmed. Apparently, they're so tough, they don't have any defense points listed. In being so, they are completely impenetrable to all attacks. Mario has only one way to defeat them, to use their power against them. The only named Iron Clefts are the Armored Harriers.
