@waybig1010101: not sure if it will work on a creature that just roars.
Well considering that the Devil Gundam is the size of a space colony and Earth at the same time with the main body being on the space colony. There is a size problem. Plus there is no way to get past the regeneration unless you use a attack filled with strong positive emotions right into the core. So factoring this and the fact Naruto and Sasuke won't agree on how to deal with Sakura gonna give it to the Devil Gundam.
@ICanKillTOAA: did you just @ reply to yourself? Well I get the idea. But if you think about it another way we just may not be able to see a way around it because we are not omnipotent. It may just be our minds can't comprehend the answer.
