He was such a hard boss fight, I think tell this day, I have not beaten him.

ryku is a hard boss

Oh c'mon He's not that hard.

He wasn't that hard to beat, if you cheezed it. If you played legit, he was hard.

near the end of the game I didn't find riku much a difficulty it probably helped that I had some kind of sonic attack to beat him quickly. It was the dragon (maleficent) that was a pain

Oh that's pretty awesome

KEYBLADE ISN'T EVEN A SWORd. IT'S A BLUNT OBJECt. KEYBLUNT OBJECT

I played Kingdom hearts so often that it is easy for me to kill Riku in this part XD

I remember just barrel rolling and gliding constantly to avoid this fucker in his dumbass batman suit.

I thought that fight was hilariously easy. I rofflestomped him until I got bored and went to the next part of the game.

Psh...he wasn't that hard. I knocked him around and said "hehehe...See, Riku? I am a badass :3"

That fight's supposed to be hard? That's news to me.

never played KH

Wait this was hard? i must be remembering wrong

I don't remember having a hard time with Riku, it was the final boss that was always a pain in the ass for me.

For me and my little 11 year old reflexes, Riku was the hardest freaking thing up to that point. Compared to him, Maleficent was a freaking pushover. Fave just for me not being the only one who had so much trouble with him. Of course once I found block and sonic dash the fight was way easier.

ACCURATE

I Could never get the original KH Game to work D: Though I Played KH2 soooooo much! There was ONE Person in the game I Couldn't for the life of me I Couldn't beat, Cloud I Think it was...with his giant-ass sword...I Mean seriously! I Managed to get him down to the last bit of life and when I Was about to attack him but was on the other side of the map he just like spun around and his sword became so huge it spread across the map! >_<

I Completed the rest of the game so much that the disc pretty much melted in the PS2 :P It doesn't work any more >_<

You think that's hard? Just wait for the Platinum Match.

The only boss that gave me trouble was the giant Ursula, that lady was a bitch to get rid of

If we're talking about the hardest bosses we faced, then I would have to say...
Yesmat from FF12..
he wil become the bane of your existence... FOREVER!!!!!!!!!!
