Pequeno Burraidh
Beag Combatiente
My guess was that Naruto had the marks because of the time he spent within the womb of a Jinchūriki. He could have been affected by Kurama during the nine months until his birth. Boruto and Himawari also have them, so it could possibly be a genetic thing.
If he does, reading about his adventures as a ninja pirate would be interesting.
I imagine that crossing him wouldn't be a very good idea. His appearance reminds me of the old Street Sharks cartoon.
Well like I told Quirk, he has one person he intends to track down, who he bumps into along that path will be the question that could make it all quite interesting.
