Todd is a kid who lives on Harvey. He, like Audrey, takes role-playing too far and believes he's a real superhero that can fly. In later episodes, he surprisingly appeared coming out of nowhere. Though, Todd may have been very hobnail.
In the original Little Lotta comics, she was such a fan of superhero "Flying Man" she made herself a costume and pretended to be "Leaping Lotta". This seems to be the inspiration for "Super-Todd".
