I think it's safe to say onooki is the strongest so yeah he's number 1
I'd put tsuande at 2 but gaara could bury her and make her suffocate witch she can't heal from her summoning is a problem but gaara sand sensing even if it multiples won't be to hard to destroy ppl say tsuande can punch through gaara sand 0.0 noooo his defense is strong as hell besides she would just seep through it and get caught in. Sand coffin and then the burial
A has 1 hand so yeah not a plus there lml plus he can't really harm or kill tsunade she can heal from anything he throws at her and he can't touch gaara or onooki cuz they can fly so yeah
Mei ... Is just Mei.....
Tsuande >= A
What y'all think if disagreegive ur order and why
