lol no. Sora with the final form = good bye TAV.
hmmm... Be looking at this post it seems that it's possible we have a new Troll in our midst.
Sora is way weaker than any of TAV. It's even possible that Sora gets some of his powers from Ventus. Sora always had help. In KH1 he had the help of Donald and Goofy. In KH2 he fought Xemnas with Riku, and possibly help from the man in the above spoiler. He has never fought a major bad guy on his own, except for Rikunort in KH1. Plus, Sora forgot all of his skills after CoM. His fighting skill now is just what he learned in KH2.
