Thanks to bfw182 for his awesome evaluation notes!
Neji Hyuga (An Unchangeable Destiny)
He has 999 HP and an impressive 1300 ATK. This makes him one of the stronger 5* characters available and due to his typing he is not bad against any enemy.
One of his downsides is that he has a short range so isn't always the easiest to get multi combo hits with him.
His Ninjutsu is a little costly at 5 Chakra and doesn't have the biggest damage multiplier but this is made up for by his large ATK stat. His Ninjutsu also has the really useful effect of being able to seal an enemies Ninjutsu for 5 turns. This is quite a good length of time and has a 40% chance which is better than some other characters. An overall good aggresive character if you are missing some of the better 6* ones.
