Shadow Possession Jutsu
Possess anyone in the range available to you with your shadow. You can extend the time and range by training.
After possessing someone, you can make them do whatever you want (physical actions only). Pretty convenient when you’re in a pinch eh?
Everyone wants a sharingan. How many times you have woken up hoping that today you will manifest it. The eye power is so cool and convenient. Memorize everything, copy any technique or literally anything and you will remember it for your life time. Exams? Study by memorizing everything or just cheat with the sharingan by seeing the hand movement of the topper(not recommended :p). Copy cool dance moves, what not. The possibilities are endless!
