Wth is with this "Healthy Nagato".

[Piratefish]

So living NAgato can do Chibaku tensei and etc while fighting and won't be stressed out???

Chibaku Tensei is powered by Life Force, of COURSE he'd be "stressed out".

But Nagato, if healthy, would have WAY more Life Force than the one who invaded Konoha. He'd be able to make more and stronger Chibaku Tensei's with ease, that IS true.

Plus, as chakra is partly PHYSICAL energy, he'd have WAAAAAAAAY more of it. As your physical energy is a bit limited when sitting in a wheelchair, unable to stand or even move properly.

I hope you know Nagato when he attacked was just transfering chakra to the bodies. But wasn't moving his own body, so the pressure was still less then what it would've been if he himself was fighting a taijutsu battle at the same time.
