Auron

Auron is a playable character in Final Fantasy X. He is a former warrior monk of Yevon, a guardian of summoner Braska, and Tidus's caretaker.

Personality
Auron is a strict, no-nonsense warrior with a dry wit who carries himself with grace and dignity, maintaining many subtle mannerisms of a traditional samurai. He is the strong silent type, speaking when he feels it's necessary—usually offering his knowledge and insight in relevant situations, or sharing stories of his past experiences as a young guardian. As a result of his devotion to High Summoner Braska, Auron is idolized across Spira by many aspiring guardians.

Auron proves his imperishable loyalty to Braska and Jecht, but, beneath the silence, he is outraged over the events of ten years ago. He has become cynical, having little-to-no respect for Yevon. Despite his normally collected demeanor, Auron harbors feelings of self-loathing. He claims to Tidus and Wakka that though he is seen as a great guardian, he considers his past self (like them) foolish and young.

Auron exhibits some fatherly tendencies with Tidus and Yuna, due to the promise he made to Jecht and Braska that he would look after their children. Auron is patient towards Tidus's childish behavior and insists he be accepted as a guardian to Yuna much to others' surprise. Tidus reminds him of Jecht, and Auron enjoys pointing out the similarities, much to Tidus's annoyance. Auron becomes irritated at hold-ups during the pilgrimage, although, he ultimately lets the party do as they please, provided it doesn't infringe on the journey. He does not hesitate to enter shops operated by the Al Bhed or use machina, despite Yevon's opposition of them.
