Unlock every character:
Play every single player mode tourneys and rank in the top three in every event.
If you have a character who is fully maxed out, you can access "Slow Motion", "God Mode", or "Extra Team Decals" for use in single player tourneys.
You can use these in Arcade Mode by selecting "My Character" and Press "White". This will only work if your character is totally maxed out.
