Python was the earth-dragon of Delphi. He presided at the Delphic oracle, which existed in the cult center for his mother, Gaea. Python became the chthonic enemy of the later Olympian deity Apollo, who slew him and remade Python's former home and the Oracle, the most famous in Ancient Greece, as his own.
Python was born when Zeus flooded the world to punish the humans. When Leto came here looking for a place to give birth after Hera cursed her, Python chased her out. After Apollo was born, he slayed Python by shooting him an arrow between the eyes then singing a song as revenge for what the monster did to his mother.
Python is mentioned as having been revived by Gaea to once again oppose Apollo. Python's recapture of Delphi is named as one of Apollo's many failures in the Second Gigantomachy. However, it couldn't completely be blamed on Apollo as he was out of commission at that time, with his Roman and Greek counterparts clashing.
While traveling inside the Labyrinth, Apollo, who was turned into a human and Meg McCaffrey overhear a conversation between Python and Nero about the capture of other oracles. The earth-dragon has joined the Triumvirate Holdings, their plan is to control the oracles so they can control fate. Python tells Nero he must burn the Grove of Dodona as it is the only oracle they can't control due to being too ancient. Apollo theorizes he will become a god again once he redefeats the monster.
