In addition to the starting roster, the game contains eight hidden characters. Depending on the specific character, you can unlock new fighters through Classic, All-Star, Mulit-Man Smash, and Special Orders. All hidden characters, however, can also be unlocked by playing Smash.
Complete the required number of Smash battles to trigger a one-on-one battle against a hidden character. If you win the battle, the hidden character is unlocked and added to your roster; if you fail, simply complete another Smash battle to try again.
