Socrates appears as a major character in Assassin's Creed Odyssey.
The game is set during the Peloponnesian War in the fifth century BCE, and its protagonist encounters Socrates in Athens and other parts of the Greek world. His dialogue frequently uses questioning and debate, reflecting the philosophical method associated with the historical Socrates.
Plato and Aristotle are also major names in ancient Greek philosophy, but they are not the philosopher intended by this question. Pythagoras likewise appears in Odyssey, though in a different narrative role connected to the Isu storyline.
Odyssey was released in 2018 and allows the player to choose Alexios or Kassandra as the main playable character. That choice means a question asking for one universal protagonist can be ambiguous, whereas Socrates' presence is a fixed feature of the historical cast. The game blends documented figures with the franchise's fictional mythology.
