Very frustrating. the game only comes with 20 characters, so you have to win with everyone. there are a couple that gets there butt whooped when it gets to 2-on-1 and 3-on-1 matches. Luckily if you go to download content you can download 2 new characters for free (po's dad Li and master chicken) that are really easy to win with thus skipping two wimpy characters of the 20. Best strategy is to hold down and keep hitting X. the repeated low punch will drain your opponents energy while filling up your awesome meter. Also what helped me in very sticky situations is to move left or right while blocking and it will jump behind the person while not getting hit.
