Iron Clefts are a powerful type of Cleft found in Paper Mario: The Thousand-Year Door. The only known Iron Clefts are the two members of the Armored Harriers team in the Glitz Pit. They are large Clefts with a blue coloration, and as their name implies, they are made of impenetrable metal. Even if Mario manages to have the Piercing Blow badge equipped, he still will not deal damage, and a correctly-timed Superguard will not hurt them either. Yoshi's Gulp provides the only known way to defeat the Armored Harriers, as it involves hitting one of the Iron Clefts with the other.
