It's been a *loooong* time since I followed any DC comic storylines, but "the" Green Lantern (Kyle) is actually just one of a large team of guardians who have all been bestowed a "ring of power" and the responsibilities that come with it. If there's now a black character with the same powers and uniform, it's probably just another member of the same group.
IIRC, every planet with life was granted a "Green Lantern" protector -- I seem to recall an alien "Green Lantern" coming to pay a visit in one of the old comics.
Last week he and Hawkgirl were bamboozled by a square-headed blue alien during their quest to rescue Superman from War World, an intergalactic take off of "Running Man".
Hey, I only watch to see what my kids are watching! :)
They're young enough where I could get by explaining the titled-comic teaches that name-calling is bad and nobody likes a bully, but if they were older and asked what those names meant, I'd have to explain that nobody's perfect and even the Green Lantern makes mistakes once in a while.
The premise was that the old Green Lantern retired and his young "ward" (wink, wink) replaced him. And we know who else has a "ward".
How straight can a guy be who goes around in leotards and an opera cape? Is flying though the air without wings a subtle hint of being "light in the loafers"? It seems to me all these so-called "superheroes" are a bit lavender.
Lois loves Superman. He saves her from the bad guys, but he never even asked her for a date. Why do you suppose that is?
