Some TMNT stuff really isn't for little kids.

Tsi-Ulu are non-anthropomorphic mutant jaguars which appear in Mutants of the Yucatan. They are whispered of as a myth or to those who do believe in them, as ghosts, due to their advanced psychic powers, which keep them from being detected, or the very least, sow doubt of their existence.

The Tsi-Ulu fight only to keep their habitat protected. Unfortunately, the many groups and individuals out there who would endanger them ensure that they are always fighting.

Their origin is unclear, but they are said to have been born as normal jaguar, but mutated by an "even stranger mutant" as kittens.
