There's a list of are listed on his page under Master Martial Artist which is under powers and abilities. I'm unclear as to how he learned the LINE system since it was developed after Vietnam and it isn't taught anywhere. But there are some stores out there with manuals to it. While most people couldn't learn it from that, someone highly skilled in hand-to-hand combat already could easily learn it from a detailed manual. He also has a lot of friends who are still in the military who he could've learned it from. According to his page he is proficient in: Nash Ryu Ju Jitsu, LINE combat system, Ninjutsu, Shorin-Ryu, Hwarangdo, and Chin Na. I know for a fact he is a highly proficient knife fighter and that the LINE system and Ninjitsu heavily involve it.
