i've seen a few videos on youtube where a bunch of samuri nobody surround roxas and sora and then roxas and sora run at eachother and thats all i know what happens (and it's more than two blocking off donald and goofy from sora)

 

sorry if i have any spelling errors

KH2, shortly after their arrival into The World That Never Was. Roxas was awakened by Axel's death, and fought Sora within his heart. Roxas asks why the Keyblade chose Sora (something he's wanted to know for a long time, and before you say it, no he wasn't referring to a person, that was a mistranslation due to gender neutral Japanese pronouns) and after finding out, Sora defeats him. His hood falls off, revealing Roxas' face, and he tells Sora that he makes a good other. Then Sora reappears back into the real world.

It's KH2 Final Mix when Roxas and Sora battled in the World that never was!! In Final mix you get to fight Roxas!! but not in NA

that video was a preview it happend in KH2 but they desided to take it out just like they took out the Roxas fight for the origanal (yes it was suppose to be in just KH2 not KH2FM+ but Nomura thought it would take to much time -_-)

i know its not kh2 (well the english version of kh2)

I believe what you are talking about is the KH2 TRAILER. They change things and locations and cut stuff out that is in the trailers sometimes.

i found either the trailer or a trailer with it. thanks everyone who helped
