Re: Can edo tensei actually be used to judge someone's strength?
I wouldn't call it someone's power not other than Tobirama.
Why? Well he was the creator of this technique in the first place, so it belongs to him.
Now, that someone learns the seals it and it's willing to kill people in order to use it, that's another thing.
Coldly thinking, it's a power that can get in anyone's asset if they'd be willing to kill.
May say that EDO Tensei stomps.
It doesn't unless you prepare long time before an actual fight because you have to get the body. That's what people forget.
Not to mention that EDOS can be sealed or get unrestrained by the most simple way: the soul's feelings, in some case.
So, conclusion I wouldn't judge someone's strenght based on EDO Tensei.
