Kingdom Hearts Help with Riku II?

I'm really sorry if this is in the wrong forum; I was gonna put it in the 'Help' forum but it looked like it was for help on KH2 only...

..Anyway, well, I can't seem to get past Riku II on Expert Mode. I'm level 46, and I'm using the Olympia Keychain...What am I doing wrong/is there anything else I need to do to beat him? O.o;;...

Thank you in advance.

 

Riku II? If this in KH2 what part of the game is it?

 

No, this is in KH1, when

Riku is posessed by 'Ansem'. It's the second fight with him.

Have Guard, Counterguard (I am unsure if it is called this in Kingdom Hearts), and Dodge Roll, when ever he attacks press Square, and then attack with a three attack combo, then run away. Repeat this until he has less the three hundred Hit Points, then it is largely the same except now he has some pretty dangerous attacks like Dark Aura that may be hard to avoid.

Also, you can level up, and you should be using Metal Chocobo for its range.

 

Just keep atacking, blocking, and rolling. When he does Dark Aura, just glide.
It's pretty simple, once you know his moves and when to block and dodge.

 

Okay, thank you, both of you! ^^ I'm getting...uh...Prepared right now. XD
