Paralysis With Hwoarang
With this cheat you must use Hwoarang. Select any opponent, any mode, and when the battle starts, press a+b (punch and kick) together a lot. Hwoarang should be continually changing his position. Your enemy won't move until 3 seconds after you release the buttons.
#Tip#: If you set a shortcut button to a+b (punch and kick) at the start menu,controller setup, this will make things much easier! I tend to make L punch and kick, and R throw. This is good advice by the best tekken player in the world!
Note: When versing another Hwoarang, this cheat will only work 90% of the time.
