Oh... my... gosh... that is by far the CUTEST damn thing I've ever seen... Tony Stark/Powerpuff girl!!!
And I have manips of her and Chris Evans... so the two should definitely meet!! :D And nosy people are always fun to try and get her life story from her.
I could see her and Tony becoming good friends perhaps a fatherish/daughter relationship?? Idk, up to you!! :)
