I dont think Madara does have it.. In order to unlock susanoo, I think you just need to unlock both MS abilities in each eye.
example
Sasuke
Left Eye: Amaterasu
Right Eye: Blaze Release
Itachi
Left Eye: Amaterasu
Right Eye: tsukynomi
Obito
Left Eye: kumi people from a distance
Right Eye: kumi yourself and intangibility
i think it works something similar to that.
I highly doubt madara has amaterasu, because he hasnt shown it yet. The only MS techniques that we know he has is susanoo.
for Sasuke Amaterasu is Blaze release.... Blaze is just him manipulating Amaterasu.. but Sasuke does have Tsukiyomi based on him using it on Danzo, Killer Bee, and other ninjas... Theory is he may be using Tskiyomi to manipulate Amaterasu.. or something of that nature...
but Blaze release is not the replacement of Tsukiyomi for Sasuke...
to use Sasunoo you must be able to use Tsukiyomi and then Amaterasu..
Tsukiyomi was named to be the first MS jutsu
Amaterasu the 2nd MS jutsu
Sasunoo the 3rd...
jutsus like Kamui, and that incredible genjutsu that Shisui had are only specifice to Obito and Shisui and they are MS jutsus because without MS they wouldnt be able to use them apparently but they are not the THREE MS jutsu that usually come with MS.. they are just specific jutsus to specific individuals.. I doubt any other Uchiha could use Kamui but Obito.. but other Uchihas who unlocked MS are sure to be able to use Tsukiyomi, Amaterasu and Sasunoo if they trained for it.....
and to the OP... you are wrong..
1. we have never seen Madara vs Hashirama... and if you even attempt to use anything outside of the MANGA to support an arguement agaisnt this then you are a noob... anything outside of the manga is NONCANON...
2. Sasunoo is only unlockable after mastering of both Tsukiyomi and Amaterasu.... says Itachi.. not exact words but you can sum that up based on what he said..
3. your arguement is invalid.. you assume that Hashirama would have lost if Madara used Amaterasu but a highly skilled ninja can avoid, deflect or even counter an Amaterasu attack. Like Raikage, Danzo, Sasuke, Jiraiya, Killer Bee, Gaara and even Obito- all who have either evaded, blocked or countered an Amaterasau in the manga at some point..
based on this thread, the fact that you have like less then 15 posts, on the assumption that you probably just joined the base TODAY and that you chose your name to be "Itachi Uchiha" like so many other fanboys, i conclude that you are a noob.... no older then 12...
