Master Eli

Master Eli is an old villain of Blue Belt from "The League of Seven" that once trained Blue Belt the art of Karate. Eli had mind controlling powers that he used on his students, but he didn't use it on Blue. He wanted to wait until blue got his black belt before he was going to mind control him, but Louis left after he received his blue belt. Master Eli, knowing that Duncan knows that he's evil, sent out his ninjas to bring Blue to him. After being proved unsuccessful, Eli fled from the scene.
