>>109356275I had a similar idea once for a story, a mother/daughter duo save a hobo who turn out to be a wizard that gives them superpowers. But when they transform the adult becomes the child sidekick and the kid becomes the adult superhero.
Their minds don't change so you have an irresponsible WonderWoman type character goofing with her powers and a responsible child being the brain of the operation, of course the adults don't take her seriously and think the kid turn adult is the real hero.
