Manacle

Manacle is a fictional superhero. Arthur was a fan of him for a short time while looking for a new superhero to dress up as instead of Dark Bunny for the comic book convention in The Secret Origin of Supernova. But when he discovered the cereal named after him, Manacle-Os, was full of sugar, he gave up on Manacle.
