Fighter's Destiny
Change Winning Pose
To change your characters winning pose, simply repeatedly tap A or B as soon as you deliver the winning blow.

9th Gained Skill
After you have gained all eight skills from Master Mode on one character, gain one different skill with a different character on another controller pack. Now go into two player battle (make sure you have two controllers in and a controller pack in each one.) Chose Win or Lose Mode and have the character with one skill lose to the character with eight. You will now have a character with 9 skills, and above the star will be a red circle.

Blow Pierre's Head Up
While using Pierre, press the L shoulder button repeatedly and Pierre's nose will get bigger and bigger. Eventually his head will blow up.

Ushi's Secret Knockdown
While using Ushi the Cow, tap the L shoulder button twice and Ushi will pull out a bottle of milk. If you are right next to your opponet she will knock them down when she puts it away.

How To Get Stars
To get stars, simply beat V.S. Com. The star will appear on the character's picture. It is my understanding that secret characters (Boro, Ushi, The Master, Robo, and The Joker) cannot earn stars. Credit Goes To: Kerry ThE Great (nuke_troop@hotmail.com) via N64cc

To change your fighter's colors and uniform, hold down the R-Button at the selection screen.
