Buttercup and Westley's daughter, introduced in Buttercup's Baby, (she is not present in the original novel, The Princess Bride). She's born via C-section after 50 hours of labor, thanks to something or someone that possesses Fezzik and guides him through performing the procedure. She and Fezzik form a close bond and spend most of their time together. Buttercup's Baby begins and ends with the madman kidnapping Waverly and throwing her off of a cliff, though Goldman notes in earlier introductions that Waverly and Fezzik (who jumps off after her) are saved from their fall by the miraculous appearance of a giant bird.
