Obviously the point in time where Roxas kicks his ass.
And that would be...
And it's also obvious if you read the subtitles, that were Riku to continue on fighting without the Darkness, he'd loose. Riku's own power wasn't enough to beat Roxas. This is something everyone knows.
:tongue: and when you say everyone that includes me
:angry: i know riku isn't strong enough to beat roxas on his own without the power of darkness or a weapon but then again it isn't like riku transforms and can't control himself. it's still riku controling the body and all the power that he gets from the darkness. the only difference is that now he's going all out and when he was in riku form he didn't even have to use a weapon until the final blow of the first part of the battle.
after that he was just dodging. i think you fail to realize that riku isn't even using a weapon the only attack he did was the dark fire. if riku were to actually use his weapon in an offensive way i think he would be more than enough for roxas any day.
if you flipped the situation around then roxas would have loss the battle a long time ago. because he can't handle riku going all out without a weapon. he couldnt handle riku's partial power while he was dual wielding
:31: and if i recall riku two was the second hardest boss in the whole kh one game.
