But Sora becomes piss weak in anti form. Sure he can move quickly and deal alot of fast hits but so can Squall and Cloud. Also his form powers come from his clothes+merging with a party member, so its not really his power.
We cant know that for sure. We only know Sora can do it with the keyblade, whats to say if Cloud or Squall were chosen to weild the keyblade, they couldnt do it too?But Cloud and Squall can't defeat 1000 Heartless single-handed
