One of the big problems with making a Native American or Aboriginal hero is that there are too many different cultures and tribes to pick just one. The Sioux, Apache, Huron, Navajo, and many other tribes exist, and picking just one would be frowned upon.
To potentially solve this problem, I suggest that in order to make an Aboriginal/Native hero, Blizzard should come up with an entirely fictional tribe. One that only takes references from real life ones, but is only canon in Overwatch’s world. Mortal Kombat does this with Nightwolf, despite it being met with some controversy (though this is due to being too stereotypical).
Would this work, or would it still be inappropriate and “offensive”?
