The juubi tobi is sommoning will be incomplete, but still retaining much of its power.
It misses out on some, but I doubt bee, kakashi, naruto and guy have the power to stop even an incomplete juubi.
Lets be honest.
In terms of power so far...rinnegan+mangekyo... any tailed beast.
I'm starting to wonder why Tobi even possesses both while he does'nt even use them.
I'd like this pokemon battle to be over and have tobi fight them all in person, instead of constantly summoning new creatures to fight them.
I sure as hel hope he does'nt turn into a giant in the final battle, and explodes when he is defeated while the main person does a homosexual pose while he explodes in the background screaming curse you!!!
But on the other hand, i know half the base wishes it to happen this way, so far of all of you who do...please, get cancer, it will be well distributed. Thank you.
