Nelvana Of The Northern Lights was an Inuit superhero who appeared in Canadian comics in the 1940s. She debuted in 1941, predating Wonder Woman by a few months.

Her complete adventures are being reprinted thanks to a Kickstarter: https://www.kickstarter.com/projects/hopel…

Obviously this is pretty cool, although my guess is that the comics might have some cringeworthy moments (Nelvana was an "Eskimo" character written by white people, and she fought "yellow peril" style Japanese characters), but maybe this will get someone to revive the character for today!
