True! You're correct in that some Indigenous tribes used bows and arrows. However, it's an image that has become kind of synonymous with Native Americans to the point of it being stereotypical. It would be like if the only Japanese person on a whole team of heroes was wielding a katana (I.E. Yamato).
His bow is very obviously too high tech for 1949 (deadlock's date) he's a holdover from neon prime. There, in the cyberpunk future, his robe and braids would be even more anachronistic. Would you be bothered if anyone else used outdated things or dressed in garb associated with their culture? One of the characters in the placeholder files has a horned viking helmet, and is clearly designed to evoke a european opera singer. What about Ivy or how she fits into stereotypes besides being a gargoyle and having a different haircut? Being anachronistic or traditional isn't a bad thing, and neither is being a stereotype. I would argue that the presence of a stereotype as the ONLY native american character probably isn't ideal, adding another character that shows a different more "modern" native american would probably be a good idea. There is of course the possibility of offensive levels of stereotype, I don't think he crosses those lines but I'm not a native american, but if he had the feathers in his hair, threw tomahawks and wore war paint all at once I'd probably think a line was crossed in a way that braids, a robe and a bow don't seem as extreme to me, an outsider.
