[Theory] Some questions regarding...

[Captain Incognito]

The Manga ofc. and mostly the Uchiha and Senju.

1. What would happen if an Senju were to obtain Uchiha DNA or the Sharingan?
Would they be able to use the Sharingan without any drawbacks or even awaken the Rinnegan?

2. The Uchiha have the stone tablet, what do the Senju have?
The stone tablet has everything written down on it about the So6p, the Juubi and both Sons, so how come the Uchiha are the fortunate one's to know the truth where as the Senju are doomed to be clueless?
Or maybe I'm just completely wrong on that one.

3. Would Koto Amatsukami work on the Juubi and if it did would it have a concience?

4. Is the longelivity of the Uzumaki an ability inherited by the Mazou since they are distant relatives to the Senju?
The Mazou is said to have a strong lifeforce.
Wait now those who are saying "Naruto becoming pseudo-JuubiJin" could use that as some sort of back up >_> oh well...

5. What led Tobirama into creating Edo Tensei?
Edo Tensei just seems to be out of character for Tobirama, not only are the requirements more than sinister (you need the DNA of the one you want to revive and a living human sacrifice as vessel for the ressurected) but it's also an offensive jutsu, having an immortal body, unlimited chakra, being controlled or having your personality completely erased by the one that summoned you and let's not forget that the one who's controlling the Edos could basically use "every" jutsu.

 

[Tayhlor Uchiha]

1. When Nagato acquired madaras eyes I'm sure it wasn't until they were getting assaulted by some ninja during the Great War when jiraiya was mentoring them that his eyes flicked to rinnegan . Although madara already had rinnegan before they were given to Nagato

 

[Seventh Sama]

1. they probably could use a transplant sharingan way more times than a non senju and they would need ems in order to get rinnegan.

2. They might've got their own sage mode (I.E hashi's sm). it seems kinda odd hasirama knew what the rinne tensei jutsu is. so they might have some ancient scroll or something that explains some of so6p's rinnegan powers.

3. I think that only works on people, but theres a chance that the jubi could see through it with its "sharinnegan"

4.according to some theorist on here( Whom i agree with) say the uzumaki naturally had that lifeforce. also i know that, they could be makeshift gedo mazos but i kinda doubt naruto still has that bijuu chakras.

5. he probably used missing nins or enemy shinobi as a body for the reanimated.
