Die, Daisy, Die! (1970)

Daisy Derkins aspires to open a new comic book store, and her efforts are complicated by the appearance of some strange new neighbors. These neighbors are actually shapeshifting lizard people from the center of the Earth who have come to the surface world to create a dating app in order to enslave human women and save their own species from extinction. Time travel, an escaped serial killer, an evil wizard, psychic pterodactyls, and more await our hero Daisy in this jam packed sci-fi/horror/comedy adventure.
