Ogdoad

 is summoned by Peppermint Butler and possesses the body of Cinnamon Bun in "The Suitor." He apparently holds the key to the Shadow Realm. Later on, Braco wanted to be a love magnet so Princess Bubblegum would love him, so he, with the help of Peppermint Butler, asked Agdoad to make Braco a love magnet. Agdoad complies after warning that Braco's request will come at a price, and then transforms Braco to an ugly creature with three feet.
