Once again... Didn't fight in COM. Roxas wasn't in COM. They even state that there are TWO new battles.well, the organization member we didn't get to fight could be roxas, remember there was that origional battle qith him that didn't make the cut in the origional game? i think that's likily too.
One is a battle we SAW but never fought.
One is a battle against an Organization Member we never fought.
Roxas and Zexion are the answers in respect.
