I have this idea of letting the players make their own avatars, creating an avatar with skin colour, hair style, facial characteristic, clothing, chakra colour, and accessories of their choice.
Having some special customizing features that can only be bought with dp or by playing the game isn't a bad idea either. Things like Kisame's pale blue skin colour, the whiskers-like marks on Naruto's cheeks, and Kakashi's forehead protector can be stuff that are bought with dp. While things like Byakugan, Sharingan, Hokage's hat, and ANBU mask can be stuff that are unlock through gameplay.
I will put up a few picture so that it's easier to understand what I am talking about. I put a "copyright of viwawa.com" on each screenshot so that I don't get in trouble for showing them here.
The images are only to help you understand, they aren't the actual thing that you will see in-game.Skin The colour of your character's skin.
Hair Your character's hair style.
Eyes Your character's eyes.
Facial Blush, scars, facial hair etc.
Mouth Your character's mouth.
Upper Clothing Shirt, jacket etc.
Lower Clothing Pants, skirt, shoes etc.
Background Replace with colour of your chakra maybe?
Pet Pets like Akamaru or summoning creatures like Gamakichi.
Accessories Earings, cigaratte, necklace, weapons etc.
A few rules thou,
1) An avatar must be fully dressed with some exceptions; upper body tattoo which replace shirt for example.
2) Anyone who tries to do something cheap like copying someone's custom avatar and then try to upload it as a normal avatar will have their avatars rejected. Players who donate or worked hard for their special/rank/kekkai genkai customization deserved to be special.
This would be a nice addition to the game. If it's possible that is >.<
