Fireheartsage
Taking place in an AU in which the wacky The Karate Kid cartoon series happened AND is inspired by the insanity of the Cobra Kai video game comes a version of the MDK world so unusual that it's practically "what if Karate Kid became anime?"
In an alternate timeline, after Samuel wins the All Valley Karate Tournament, an ancient Okinawan shrine with great mystical power returns to earth. With the power of the shrine, various fighters are given powers! The Miyagi-Do has gained ice powers (like the game) and the Cobra Kai has gained fire powers (also like the game) while the Black Dragons have gained earth powers!!! However, neither Samuel Parker or Ramon Aguilar are given the same abilities as their classmates and senseis! And when a group of people in skeleton costumes attacks the dojos of Miyagi-Do, Cobra Kai, and Black Dragon, all dojos point the finger at one another. With an all out super powered karate war on the streets of the valley, can Samuel find out who caused this insanity?
