It was stated by Tobi during his fight with Konan that Izanagi can only be
used by those with both the DNA of Senju and Uchiha. We also know this is how
the rinnegan is awakened, so why didn’t this happen?

If Tobi could use the izanagi, which requires both Senju and Uchiha DNA, then why wasn’t he able to awaken the Rinnegan on his own?


Technically Izanagi doesn't require both the DNA for activation as mentioned
[here](https://naruto.fandom.com/wiki/Izanagi) but to maintain it for a long
time both the DNA are necessary.

According to me Obito doesn't have any direct intake of Hashirama's DNA. All
he is able to do is sort of wear the Black Zetsu which doesn't lead to mixing
of DNA.

Tobi was not able to awaken the
[Rinnegan](https://naruto.fandom.com/wiki/Rinnegan) despite having both Uchiha
and Senju DNA because he was missing a certain step in the evolution, and that
is, the Eternal Mangekyo Sharingan.

> answers](https://anime.stackexchange.com/questions/48995/would-naruto-
> awaken-rinnegan-if-he-take-sharingan-from-sasuke/48997#48997))

The evolution of the Sharingan involves firstly awakening the Mangekyo, then
after a combination with another family members Mangekyo, it evolves to an
Eternal mangekyo sharingan, after which adding Senju DNA to the mix awakens
the Rinnegan.

Tobi's Sharingan never reached the EMS and so thats why even tho he had
combined both Uchiha and Senju DNA, he still was not able to awaken the
Rinnegan.

At first, it was believed that the mixing of Senju and Uchiha DNA resulted in
the Rinnegan but it was later in the series it was clarified that it's not
necessarily the DNA of both that is needed but the chakra of the Sage of the
Six Paths that awakens the Rinnegan.

This was done by Madara combining the chakra of the Sage's Sons Indra and
Ashura who had been reincarnated into himself and Hashirama respectively. Of
course the only people who awakened the Rinnegan (aside from the Sage) were
Madara and Sasuke (who got his Six Paths Chakra directly from the Sage) who
were both Uchiha with the Eternal Mangekyou Sharingan so it isn't known if the
Sharingan or any of it's stronger forms is required for the process.

In the filler episodes that show the Sages Past, he awakened the Rinnegan
immediately after unlocking the Mangekyou stage [There were no other Uchiha-
Eyes to steal back then] but as it's filler it probably cannot be considered
canon.

Tobi may have had some of Hashirama's Cells implanted through his prosthetic
white side which likely contained some amount of Ashura's Chakra but he lacked
Indra's Half of the Sages Chakra.

Additionally, it took Madara decades for his EMS and the eye which he
sacrificed for Izanagi to transform into the Rinnegan so Tobi would perhaps
not have had the time even if he somehow possessed Indra's Chakra.

Izanagi does not require Uchiha and Senju DNA. As long as you have sharingan
you can use Izanagi if you know how to activate it.
