As far as I can tell, there isn't a "warrior within" for Wii. I think maybe you mean rival swords? There is an Arena level in Rival Swords and no Arena in Warrior Within. I haven't actually played that game but I found info that might help.

To beat the Arena:
Continue down the path to see a large behemoth. Head into the arena to trigger the boss battle.

THE BUTCHER PART 1
This boss cannot be weakened conventionally. Striking him will not hurt
him so you'll need to blind him permanently in order to defeat him.
Around the arena are two ledges to climb up. Access either one and
climb up to the top of the arena.

STRATEGY:
Once the battle starts, move upwards to find the first walkway with the
stab squares. Access the stab squares and jump your way to the top.

Cross the ledge and make the long jump towards the boss. Just like the
Quick/Speed Kills, the dagger will shimmer each time for maximum
damage. Press the button for each shimmer to blind the boss's eye. Once
the Prince blinds the first eye, he jumps down and it's time for the
second eye. Find the second walkway and head up to the top ledge.

Jump the beam towards the boss and use the Speed Kills to blind him
permanently. Now that it's blind, you can start doing some damage!

THE BUTCHER PART 2
Slash away at his legs like crazy! Use evasive rolls and keep slashing
until he finally keels over. After he keels, press the Quick Kill
buttons to finally destroy the boss.
