Marco Rodrigues was an apprentice of Ryo Sakazaki. When he became a black belt, he opened a dojo in Brazil and started teaching Kyokugenryu Karate.

To prove the might of the martial art, Marco entered the "King of Fighters: Maximum Mayhem" tournament. When he returned, he learned that all of his best students got beaten up by the local "Gym Buster" and the dojo trashed. Hearing that, he now seeks the maniac.
