My niece created a superhero alter ego for herself called Daisy California. I believe she has the proportionate strength of a daisy. Also, she can fly (she manipulates the molecules around her body so that they lift her and carry her). She is often forced to rescue her Uncle Ricky, who is a sort of inept sidekick.
Anyway, I am making a comic for her; the first adventure, in which she battles the nefarious villain Stranger Danger and his ice cream truck of doom, can be read here, if you are so inclined.
