Captain Cavity

Captain Cavity is a supervillain in Metroville and arch-nemesis of Floss Man. He has no superpowers, but regularly constructs machines and technologies that can compete with superpowered individuals like Floss Man. While few of his inventions have anything remotely to do with dental hygiene, Captain Cavity almost always names and designs them to have the appearance of relevance to Floss Man's quest to support oral health. In part, this is due to Captain Cavity's own motivation to be the evil that rises up to fight the good, which in this case is Floss Man, but on a deeper level it is his satirical way of pointing out that Floss Man's own endeavors rarely have much to do with teeth in the first place.
