You guys do know that there has to be more drive forms than that. This isn't really a spoiler, but my friend told me that there are other drive forms. He didn't go into specifics cause I'm totally anti-spoiler, but i can just think of how Nomura would want to let you fuse with Mickey, Riku, and of course... Roxas. This is only my second post so tell me if I'm f***ing up on something.
