She is Steelstroke, and she gave birth to the Wilson's! She is a goddess sent here with Steelpool, to give birth to the greatest mercenaries in the multiverse!
The only downside: she lost her godhood through the birth process. And Steelpool lost his godhood in a car accident. Dumbass. Anyway, she's been shacking up with Thor on and off after they brought her into they're godhood.
She a ho. kinda like one of her lesser son's, Lois.
