You would have remembered Fantastic Max animated series where a little baby with the ability and intellect of an adult was a super-hero. Only his allies would know about his powers and abilities. In front of his parents and society, he would behave like normal baby.
Now here is another kid super-heroine who may not be as young as Max but she is still a child. We must call her super-heroine as she has to fight evil and restore peace in the world.
