This is a challenge Straight up I've noticed there is not a lot of seven deadly sins and naruto crossovers and there's a lot of potential here so what this challenge is to going to take this premise and expand on it
so first naruto is a hybrid of a fairy and a demon back story is that his mother was a demon and his father was a fairy do with that as you will kept away from the war after being abandoned. he was sealed up with the demon tribe 3000 years ago and when the 10 Commandments are freed he was freed as well running away from them Hijinks ensues
Looks: black fairy wings that look like there sucking light in and Change to demon wing when using the power of darkness medium length hair with stripes of red and blonde in it red eyes
Weapon: uses a staff resembling kings
(The fun one) Powers: so his magic Is "command" a lesser version of "absolute order" only medium high and above are able to resist/disobey his commands
now this three are a must have if u want to change thing go right a head
I don't care if you steal any of these ideas and use them in the seven deadly sins and Naruto crossover
