"Yuna! This is our story! Now let's see this thing through together."
Tidus (pronounced "TEE-dus") is the lead hero of Final Fantasy X. His name is taken from the Okinawan word tiida, meaning "sun," and this suits his character throughout the game.
Final Fantasy X begins with its focus on Tidus, the cheery and childish star athlete of his futuristic hometown, Zanarkand. A giant monster called Sin attacks the city, transporting him into the new, seemingly primitive world of Spira. Tidus's story revolves around his desire to return home to Zanarkand and his involvement in Spira's fate while attempting to return.
Final Fantasy X was one of the first fully 3D RPGs with an entirely voice-casted script. Due to its critical success, it was the first game in the series to be followed up by a direct sequel: Final Fantasy X-2. In this game Tidus is not the main character, but rather the quarry of the main characters' quest.
