Perceptive, observant, attentive and responsible 

His dynamic with Amaya is enemies to friends to lovers while as Amaya only ever saw him as a very close friend to slowly lover. He's mature, responsible, dependable, caring and extremely intelligent...as well as done with Amaya. He can't keep up with her, yet won't let go either. They bicker, fight, argue all the time, still they understand each other the best, they know each other the most.

Best friend...or something more?

A sadistic, cruel, yandere monster. He's aggressive, violent, abusive, gaslighter, all sort of toxic. A character that is purely evil for the sake of evil with absolutely no moral compass. He is not the character that changes for better or grows to become good, he remains corrupted and just as incredibly inhuman no matter what.

Fix him?

A self inserted OC (mostly shipped with Itachi). A miracle medic with an incredibly dark and tragic past but she remained a sunshine. Her last name is Kyohime and she belongs to the Kyohime family (it's just made up by me, not canon). She was born and raised in another village but when she was 15 she came to konoha and started there ever after. She was rescued and is the best healer.

Innocent, naive, sweet and charming.

 Anti-Villain of Konoha, morally gray pacifist...

An almost accurate character of Itachi Uchiha for the sake of role-playing. Although his canon backstory is given in summary, there is a personal alteration done for the sake of continuity as well. A character made for various individualistic AU generation and portrayal of his original character in those situations as believably as possible. Although he can be used for playing out fillers in the canon Naruto/Shippuden universe.

AU of your choice.

Calm, quiet, intelligent, observant and perceptive

Different personal AU where he lives. Canonically accurate Itachi. Mostly quiet, unresponsive, cold and calculated. Yet somehow manages to be irritable, slightly irrational and angrily expressive around his female best friend. A complete genjutsu master and a genius with basically everything he does, yet a fool near his childish and airheaded bestie.
