Game:Yuffie

The great ninja Yuffie is normally an ally that occasionally assists in Sora's journey however is also encountered in colliseum matches as an enemy boss. Her way of battle speciallizes in stealth and agility, thereby making a tough apponent. Yuffie uses a Shuriken to attack from great distances.

Pegasus Cup
In the Pegasus Cup, Yuffie appears alongside Leon as the first seed. Unlike Leon, Yuffie carries out long-range attacks, and Yuffie has less HP than Leon, so make use of her attacks and defeat her before concentrating on Leon.

Her normal attacks include throwing her Shuriken towards Sora - dodging it will be futile, because the Shuriken follows Sora wherever he goes. Instead, lock on to Yuffie and deflect her attacks with Guard. If the Shuriken is successfully deflected, Sora will gain more experience. Also, if the deflected Shuriken hits Yuffie, it will stun her for a while - take this opportunity to hit her with the Keyblade as many times as you can.

When she powers up the Shuriken and makes it larger, be on your guard: the large Shuriken is very difficult to deflect, or it cannot be deflected at all. As with Leon, do not be shy about using the Keyblade because Yuffie can heal whenever her HP is depleting. Do also remember to heal whenever necessary.

It should be noted that in the Hades Cup, Sora will have to fight Yuffie again, but this time she is alone.
