Hear me out...

My ideal teacher for Sarada would be Kakashi because other than Sasuke, he would be the perfect Sharingan teacher. However after looking at Sasuke's life I am sort of changing my thinking. Sasuke was seeking power and that's it, and he found Orochimaru (or I guess orochimaru found him...) and he gave Sasuke immense power which makes me think maybe Sarada doesn't need a teacher who knows a lot about Sharingan.

Since Rock lee is the top Taijutsu user in the world or at least top 2.... wouldn't he be an ideal master for Sarada? With the strength of the hundred seal plus the training rock lee would put her through to master the gates I think she would be virtually unstoppable. Like if she tapped people's foreheads like Sasuke does, would she just decapitate them? It would be insane. Also since she is constantly healing herself would opening the gates even have an effect on her body?

Basically, I am putting this out there as an alternative to her awakening MS. It isn't clear yet how she would awaken MS so maybe instead she could be the most devastating taijutsu user ever.

btw I know that this has like a 0.0000001% chance of actually happening but I just think it would be dope to see and fun to discuss.
