Since y'all brought up storm's alt universe kids and powers.. What kind of abilities do you expect Storm's kids to have? I always assumed if she had a kid with Logan, she would have a child with animal telepathy, environmental empathy and low to mid leve metamorphic abilities. Or a who could manipulate the 4 elements with a healing factor.. I could even see the child of Storm and Wolverine having a kid with abiltiies like Elixir. I would hate for her kids to have her same powers.
As far as T'challa, I figure a kid would have high level energy manipulation or a psionic power.. Also the kid would have top level physical abilities due to Black Panthers abilities
And if she had a kid with Forge, mystical energy manipulation all the way. a magical mutant
