Ninja Of War wrote: Why couldn't Obito use Kamui? He has been able to suck in an explosion with Kamui, so it's quite logical that he simply used Kamui to suck in Amaterasu. The other option would simply be to detach his burning zetsu arm and replace it with a new one. Except that he'd be sucking his own body parts away to the Kamui dimension along with the flames, which does not solve the problem. The Zetsu bit sounds quite plausible, though.
