Who's This? She's one of the world's very first female superheroes and not a DC character, so of course not in Who's Who. I'm hijacking this feature in the wake of my post on Golden Age Canadian Comics is all!
How you could have heard of her: If you were a stamp collector in 1995, Canada Post came out with a series of superhero stamps that included Superman, Captain Canuck and yes, Nelvana. Name sound familiar? That's because John Byrne paid tribute to the character by naming Snowbird's mother Nelvanna of the Northern Lights (extra "n"), daughter of Hodiak (close!).
Example story: Triumph-Adventure Comics #1
Just then, they hear an explosion near the shore and deduce this is obviously the work of Kablunets (a word that means "evil white ones"), which forces Tanero to disguise himself, for like their father, he is cursed never to be seen in his true form by the white man. With the help of her magic cloak, Nelvana does the only reasonable thing under these circumstances - she turns him into a Great Dane.
I don't have access to all her adventures, but according to my research, over the next 7 years, Nelvana would visit the underground kingdom of Glacia, team up with Johnny Canuck, travel to other dimensions, fight the Axis powers, and adopt the secret identity of secret agent (very secret then) Alana North. I'll try to bring you as much of that as I can in future installments.
Who else? Well, these early issues of Triumph also feature such Canadian icons(?) as Spanner Preston, Clue Catchers and Tang the colt. Maybe they should see some play on this here blog? Or what about other Golden Age Canadian heroes?
