Lord sasuke rustles every bodies faves thank you and sasuke sama solos, dat sauce.
But to be fair just stuff like orochimaru being the main villain even though sasuke negs him laughable difficulty while chowing on meatloaf. And sasuke is batman making sure another kaguya, madara, obito, etc never come back again as he journeys the world for atonement. He also is going to have a gohan/piccolo moment with bolt. Series begins in April and lasts for a few month then boruto movie in August. That's just the major things
Fanfic until proven otherwise:Sasuke with his rinnegan learns to use and masters all other MS techs and other possible Rinnegan techs like limbo since sasuke's rinnegan comes straight from hagoromo himself who taught all the ninja moves. With his mastered rinnegan sasuke can use virtually any tech including dust and dark style and kumai since that is the special ability of his rinnegan. His limbo is different from madara's though. Naruto still evens him out with access to all tail beast powers to use RSM. But regular BSM Naruto gets beat mid low diff. Sasuke also replaces his left arm via asura path and naraka path. With all this power at his disposal sasuke still believes that he should protect the world from another kaguya regime. In the shadows, lord sasuke rustles your fave, he's on double rinnegan juubidara level but he gets beat by prime kaguya, no one can beat prime kaguya not even solo rock or solo cage.
Fanfic over
That's pretty much it though
