The vermis is in Plumbers Don't Wear Ties too and there's also a fightable Chthon in Castle of Koohoo. Episode 1 of Gotshun's Lost Levels ends with 3 (!) consecutive Armagon battles. Armagon himself of course comes from the official mission pack Scourge of Armagon. You fight Nyarlathotep in his pharaoh form in both the other mission pack Dissolution of Eternity and the Nyarlathotep map that comes as an add-on to Something Wicked. The latest version of Arcane Dimensions (v1.5) features a super-scrag boss and many maps in this mod end with epic boss or horde fights. Also, I haven't played it yet but I've heard that the unofficial mission pack 3: Abyss of Pandemonium features several unique bosses.
