Hyper Cleft

A Hyper Cleft is a bright green Cleft with purple details, capable of charging its attacks to do a very large amount damage, like the other "hyper" enemies. Like normal Clefts, they are spiked, so jumping on them will not work unless Mario is wearing the Spike Shield badge. Also like normal Clefts, they have relatively high defense, so using an attack that flips them over or pierces defense is effective.

Paper Mario
In Paper Mario, Hyper Clefts appear in Gusty Gulch alongside Hyper Goombas and Hyper Paragoombas, effectively acting as a more difficult substitute for a hyper version Spiked Goombas. They act like normal Clefts on the overworld, but are much faster. While charged, their attacks cause eight points of damage if not blocked.

Paper Mario: The Thousand-Year Door
Hyper Clefts reappear in Paper Mario: The Thousand-Year Door in Twilight Trail, where they again appear alongside other "hyper" enemies, which now includes Hyper Spiky Goombas. When charged, they now do nine points of damage if not blocked, but are no longer as fast as they previously were on the overworld. A spikeles subtype called Hyper Bald Cleft appears earlier, in the Glitz Pit.
