Sphinxes, or Sphinges, are mythological creatures that originated in Egypt, and was later imported to Greece, with the word "sphinx" itself being of Greek origin. The Egyptian sphinx is most often depicted as a reclining lion with the head of a human man. Less commonly, it will be a lion with the head of a ram, in which case it is called a "criosphinx." The most well known example of the Egyptian sphinx is the Great Sphinx at Giza.
The creature was later imported into Greek mythology, where it became a daughter of Echidna and Typhon. This sphinx is described as having the head (and in later times, breasts) of a woman, the body of a lion, and the wings of an eagle. It sat on the road to the city of Thebes, and asked all who passed by a famous riddle: "What creature walks on four legs in the morning, two legs at noon, and three legs at night?" She killed all those who answered wrong. Oedipus finally gave the correct answer of "man," and the Sphinx immediately killed herself in rage.
The Greek version of the Sphinx is depicted as treacherous and merciless. Those who cannot answer its riddle suffer a fate typical in such mythological stories, as they are killed and eaten by this ravenous monster. However, not all Sphinx in Greek mythology were malevolent as some were actually benevolent in a sense. In addition, the Egyptian sphinx was viewed as benevolent, but having a ferocious strength similar to the malevolent Greek version and both were thought of as guardians often flanking the entrances to temples.
A Sphinx is given to you by Miranda (if the player is male) or Mubiora (if the player is female) after defeating the Legion at Studio Alto.

"To think the cognitive version of a person would transform into such a horrible monster and attack us..."
—Yusuke Kitagawa, Persona 5
CognitiveWakaba Isshiki is the the boss of Futaba's Palace and takes the form of a giant Sphinx with Wakaba's head. Unlike most Palace Bosses, she is not the battle form of a Shadow Self (and in fact Shadow Futaba appears as an ally), but a Cognition formed from Futaba Sakura's survivor guilt, desire for self-destruction and belief that she was an unwanted burden on her mother. (In other words, this is how Futaba views Wakaba.) As Futaba never interacts with others, Cognitive Wakaba is the only Cognition within the Palace. She has a spiteful and vengeful personality, existing only to "punish" Futaba for being the reason the real Wakaba died (as Wakaba sacrificed herself to save Futaba) and repeatedly mocks both her and the Phantom Thieves of Hearts for being childish and useless.
