Variant versions of classical monsters: the harpy (a classic feather-winged version nistead of the bat-winged version inspired by the Jason and the Argonauts movie), hamadryad, serpentine hydra (legless instead of dragon-like), sylvan centaur (a gentler version), infernal archfiends (a tribute to Gygax's type I-VI demons, including the balotaur, dracodemon, thanator, and hellazon), and the Anakite champion (a giant, son of Dagon).
