CBC News has debuted new details about the young Cree superheroine to be introduced next month in DC Comics' Justice League United #0, by Jeff Lemire and Mike McKone.

Code-named Equinox, Miiyahbin is a 16-year-old from Moose Factory, Ontario, whose power comes from the Earth and changes with the seasons. As revealed in October, the character is inspired in part by Shannen Koostachin, a teenage activist who lobbied the federal government for a new school in Attawapiskat First Nation, on the James Bay Coast. Koostachin died in a car accident in 2010 at the age of 15.

Lemire Leads "Justice League United" to the Great White North

"Creating a teenage female superhero was interesting to me because, generally, most superheroes are white males," Lemire told CBC News. "We need diversity and we need different personalities. You need very distinct voices for personalities on the team or else you just start writing the same character in a different costume."

To conduct research for Equinox, the Toronto-based creator of the Essex County trilogy traveled north to Moosonee and Moose Factory on James Bay, where he received feedback from local residents.

Equinox joins a Justice League roster that also includes Green Arrow, Animal Man, Martian Manhunter, Hawkman, Supergirl, Stargirl and the now-Canadian Adam Strange.

Lemire, who appears this weekend at Emerald City Comicon, is also featured in a CBC video, below.
