Corset

Corset is the main villain in Panty and Stocking with Garterbelt. He is the mayor of Daten City and the father of Scanty and Kneesocks who first appears in the episode D.C. Confidential, as well as Garterbelt's evil counterpart who seems to have known him prior to the story. Corset's goal is to unlock the gates of Hell and unleash the Ultimate Ghost to take over the world. To do this, he requires a key known as "Hell's Monkey", which turns out to be Brief's penis. While normally skinny, he transforms into a much more muscular form during the climax, where he is apparently killed by the giant feet of Panty and Stocking's divine mother. However, at the last minute after Stocking is revealed to be a demon and cuts Panty into 666 pieces, Corset inexplicably appears as a small gray blob from Brief's penis and leaves with Stocking, telling the others that they are going to try and unlock another gate to Hell in the neighboring Oten City, leaving behind a trail of the pieces of Panty.
