Iron Clefts are a powerful sub-species of Clefts found in Paper Mario: The Thousand-Year Door.

Trivia

 * A special attack by the Yoshi Kid provides the only known way to defeat the Armored Harriers for the first time. If Grubba (or Jolene) asked the player not to use any FP, or not to let the partner attack, that would make complete victory impossible for that particular match. It is unknown whether or not they can actually make these demands for this particular fight, but its unlikely.
 * Since every character in the major league would have to beat the Armored Harriers in order to stay ranked above them, it is plausible that they have other weaknesses (or that the Major League fighters knew their main weakness).
 * The green Iron Cleft is supposed to be younger. This could be based on the fact that Luigi is younger than Mario.
