Take note, if this was the case then:

Ventus wouldn't have met aqua or terra

Kairi wouldn't have met riku or sora

Sora, kairi and riku would never have gotten their keyblades (Maybe)

Riku wouldn't have gone to the dark side of the force and become less of a d!ck

 

Roxas and namine(And xion D:) wouldn't exist

Actually, nobodies, unversed and heartless would not have existed at all

Hmmmm....Derp......

No please no more time shit

It was said in 3D that history can't be changed, this would be impossible.

It's already been stated this would not be possible, through the rules of time travel in the game. I dun see anything similar happening either.

If xion doesnt exist then NO!!!!!!!!!!! Not the case then!

Actually, Heartless existed before hand, just in such puny numbers that they were insignificant at the time.

Maybe this ending might be possible.

Well, i didn't think it up, just thought like sharing the brain food. ;P
