Foot Mystic (2003 TV series)

The Foot Mystics, also known as the Heralds of the Shredder, are the servants of the original Shredder. They each command the five elements: fire, water, wind, earth and metal. They can be controlled by an artifact known as the Heart of Tengu.

At some point in time, the Mystics came under the command of the Utrom Shredder, who used them as guards in his tower in New York. But secretly, they blackmailed city officials to creating the Keystones around the city. They also sent a bone demon to follow the Ancient One to the Lap of the Gods to secure the Shredder's body and artifacts. But the demon failed and the artifacts were separated.

When the Turtles returned to finish off the Shredder, the Foot Mystics were one of the obstacles that stood in the way. They seemed unbeatable until Splinter used the Sword of Tengu without the gauntlet to temporarily dissipate them.

The Mystics soon made a reappearance, under Karai's command, who were ordered to interrupt the Turtles' meditation and destroy their spirits, putting in their worst fears: such as the deaths of their friends, their existence known to the world and their enemies joining together. But Splinter saw through the deception, so the Mystics tried to attack them directly but were defeated. Karai was severely angry at this failure though they were able to secure the location of the Turtles' lair.

Soon tired of Karai's rule, the Mystics decided to pave the way to freedom. They contact Agent Bishop, claiming that the Heart was an alien archive, so he should take it. With the Turtles' help, they succeed and tell him to put lasers on the heart, which destroys it. The Mystics turned into their true forms and escaped the Foot tower.
