he would need to use a shinra tensei strong enouch to blow away an entire island. sure he made one big enough to wipe out konoha, and used up God realms power for a while, he will have to take chakra from the other paths to make a shinra tensei big enough to destroy an entire island, cuz thats what it will take.

truth is, without edo tensei pain>>>>kabuto
