Katal is a member of Foundation X and a supporting antagonist in Movie War Mega Max. He is one of Lem Kannagi's two subordinates and has been modified by him to be able to turn into a Mutamit named Suddendath.
Katal accompanied Kannagi and Solaris on their mission to recover the SOLU from the meteorites that crashed to Earth. Despite encountering resistance from the Seven Legendary Kamen Riders, they were able to successfully obtain the substance. However, as they were transporting it they were intercepted by Shotaro Hidari as Kamen Rider Joker. Following another struggle with the Kamen Riders, they lost the SOLU when it was knocked into a sewer.
Katal later went with Kannagi to capture Nadeshiko Misaki, a being of SOLU who took on the form of a human. Katal fought Kamen Rider Fourze and the Kamen Rider Club to get to Nadeshiko but was killed by Fourze Rocket States's Rider Tailspin Crusher.
