This is a great way to beat any character with level 9 AI! Hope this helped!
First, pick a fighter. (Oh, and set yourself to be a CPU.)
Watch the fighter in action. Keep watching until you think you have it down in your head.
Practice the skills you just memorized until you master them.
Start at that fighter being level one, and have him/her go up one level each time you beat the fighter several times in a row.
