The game has four secret characters that can be unlocked in Tournament mode after having beaten all of the previous characters. The four characters must be fought in sequence, and the matches between each character need to be triggered on a particular arena by performing a special trick. All of the tricks are done during the second round of each match and require that the character you are playing as wins that round. In addition, all of the tricks require that your player character possesses a Second Wind, acquired by performing a "perfect round" in a previous round (this can be seen over your character's health bar). The following are the tricks for each of the unlockable characters:

• Black Dragon - triggered on the Graveyard (second match). Do not use C or Right Shift to kick for the entire round.
• Major Trouble - triggered on the Lava Pit (fourth normal match). Do not use B to block for the entire round.
• Voodoo - triggered on the Roof (sixth normal match). Do not use A or Left Shift to punch for the entire round.
• Gulab Jamun - triggered on the Cliffs (eighth normal match) by taking no damage in both rounds.
