How do you get different overdrive modes in FF-X?

In Final Fantasy X, different Overdrive modes are accessed through the Overdrive menu in the character’s status screen. Each character has unique Overdrive modes that can be unlocked by using their Overdrive abilities in battle. Additionally, players can choose the Overdrive mode preference, such as "Stoic," "Warrior," or "Comrade," which influence how Overdrive points are gained.
