it is a well known fact the comics of the rival company exists in the others universe. Stark will reference batman often. DC often discussed the X-Men, avengers, and fantastic 4

killer B survived so once again you are wrong

nope it's based on lifespan and vitality. Most die instantly. in the original story Mito lasted months up to a year until she died. Uzumaki and anyone with a strong alien bloodline can last longer if they have strong enough vitality. Even Killer B managed for a good while.

maybe imu I don't know enough about one piece but i thought it is a kaguya equivalent

There is also the factor of utility. ninjas can do way more than pirates and marines. Even with the numbers advantage ninjas can run on water and fight without any real weaknesses. The devil fruit users are the primary combat for many of which have no long range ability and can be knocked into the water for a instant loss.

I have a feeling this isn't going to be that strong. it is just like adding another layer of armor. sure the normal humans will benefit but the big guys armor probably won't be much weaker that haki to begin with.

he should give matatabi to the uchiha as a joke. And gyuki to the hyuga.

he's fought alongside the ino shika cho and is receptive to criticism. He is the only jonin with absolutely no ego and will listen to his team without question.

he has the rashomon contract (like Orochimaru) and the slug contract but rarely uses either. He has his own sage mode.

He is in the senju compound he could have learned the name from Tsunade or Mito by asking.
