Tidus is never actually directly referred to by his name in audible dialogue. People will refer to him with impersonal pronouns. This is due to the player being able to name Tidus at the start of the game, and this being Square Enix's first voiced Final Fantasy game, they weren't sure how to handle a variable name. Tidus' name pronunciation has been debated, but was confirmed to be pronounced "Tee-Dus" by James Arnold Taylor, the voice actor for Tidus.
