Notes

Mikes story: He was born incredibly talented and had unbelievable strength and speed and raw physical ability, by the time he was in the academy he was at least chunin level then he unlocked wood release, but he wasn't done there he decided to try to make his own kekkei genkai which was considered impossible but because of his extreme talent in almost everything by the time he was Chuunin he was able to use flora release, then he also by this time had mastered almost all the nature elements. But after the Chuunin exams he became partially corrupt and thought he didn't have enough power to become kage and simultaneously orochimaru was looking for a new body and saw mike as his perfect chance, so orochimaru befriended him and eventually mike was the first person to develop and the only person to master metal release. he soon learned that orochimaru was not on his side because of his evil ideas of killing people and taking their power and eventually becoming all powerful. so orochimaru at this point had so much power he was thought to be on the level of even some otutsutski members. by this time Mike was seeing how if he let orochimaru get his body, the world would probably be over. Orochimaru then decided it was time for him to attempt to kill mike, so he tried to assassinate him or at least chip away at his power as he was the only one standing in his way, then they had a big ass fight that lasted over 30 days straight and mike was on the verge of death, orochimaru was still probably at half of his strength, so mike was forced to use 7th gate(at the time that was enough to kill him because of how badly he was beaten up and orochimaru at the time could nullify regeneration but all mike was able to do was seal away a massive chunk of orochimaru in his own body as he died, and orochimaru was left lying there because of his massive loss of chakra and power,
but then a hooded figure comes out of the shadows(kabuto) saving orochimarus life but he was in really bad shape and couldn't fight or anything for decades(kabuto was able to get him a new body which was one of the three great sannin at the time), as the village mourns Mikes death and tries as much as they can to heal him, even some village members were willing to use reincarnation jutsu on him but the sannin stopped him because that's not what mike would've wanted, also his sword which had untold power was also put in his grave, even though it could've been used by the village they all knew that he would've wanted to keep it even in the afterlife, as that was a sword his dad gave him and he's kept it and got it upgraded ever since then, making it having extreme power, this is currently unknown to all except the Hokage and is continuously passed down , and no one has touched his sword since because it will probably have too much power for someone to wield .
