Auron (FFX)

Auron is an adult man of 35 years old and 182 centimeters tall.
Auron wears a red haori held closed with a black and blue strap with two brown belts wrapped around it. Auron tucks his left arm into the front of his haori, making it appear as if his arm is in a sling. He removes his left arm from the haori when fighting, but his right arm remains in its sleeve. This look (along with the jug at his side) is a tradition among rōnin, masterless wandering samurai, and is likely an homage. He wears a black armored gauntlet on his right hand and an armor brace on his left forearm.

Auron wears a brown pauldron on his left shoulder intricately decorated with tan, green, and blue patterns with a beaded ornament hanging from it. He wears black pants and shoes with brown straps and triangular metal plates. Auron wears a black shirt with a grey turtleneck with brown straps crossing over it. His hair is black with grey streaks held back by a gold ribbon, and he has some stubble on his chin.
Auron has a scar on the right half of his face above his eye, which remains closed as a result. His left eye is amber-colored, and he wears black sunglasses. On his right hip, Auron carries a jug with the word "Nog" written on it (in Spiran script), a term used to describe some drinks, including rum. The drink appears in two of his Overdrives: when he performs Banishing Blade, Auron takes a swig and spits it onto the sword, and when he uses Tornado, Auron throws the jug into the cyclone to ignite it. The former is likely an homage to Japanese samurai who would spit sake onto their swords to "feed the spirit of the sword".

Auron, 25, is a warrior monk working in Bevelle. One day he is visited by a childhood friend, whom he knew nothing about except that he had married an Albhed, which was frowned upon. This old friend was Braska.
Braska tells Auron that he intends to become a summoner, a white mage who summons spirits of old called Aeons. Then Kinoc, a friend of Auron, tells him that he has been offered the position of High Monk of Bevelle, provided he marries the daughter of a venerable Lord, Lord Mika. Auron refused the hand of Mika's daughter and was banished and excommunicated.

Braska then asks Auron to be his guardian, and Auron readily agrees. Braska explains that his wife has died because of Sin, and that his 7-year-old daughter, Yuna, is with the Albhed. Before they leave Bevelle, they hear that a guy who is not from Spira has been imprisoned. They go to see him, and it turns out to be Jecht, an arrogant drunk who claims to be from Zanarkand, despite the fact that the city was destroyed 1000 years ago. Braska makes him his guardian, although Auron is not very happy about it, because he thinks the newbie will attract trouble, and he was not far off. Despite that, they become good friends.
When Braska goes to the city where Jecht comes from, Zanarkand, they learn that one of the guardians must die to be the Supreme Aeon, the most powerful spirit that overthrows Sinh, but in exchange, after he transforms, that aeon will become Sinh and the cycle would start again. Braska and Jecht decide to die, but not before Jecht makes Auron promise to bring Tidus to finally destroy Sinh, his father.
When Sinh is defeated and the other two are killed, Auron faces Yunalesca, seeking to avenge his friends, as they had died in a spiral of deaths that had no end. Yunalesca defeats Auron and leaves him mortally wounded. As he flees, badly wounded, he finds Kimahri, and orders him to take Yuna to Besaid, after which he dies. But the promise he made to Jecht revives him.

He is considered "the best guardian of all"
He's not much of a talker, he's tall and sometimes a little insensitive. He joined the group to protect Yuna, as he promised Braska, and to defeat Sinh.
His character, far from being docile, is very flexible and in many cases like an overprotective father. Crude and with a sour look, he is perhaps the most discordant person, since with his rude and impolite attitude almost always comes the sense of loyalty that forces him to keep the group together.
Auron is a strict and no-nonsense warrior with a sharp wit who carries himself with grace and dignity, maintaining many of the subtle mannerisms of a traditional samurai. He is a strong, silent type who speaks when he deems it necessary, usually offering his knowledge and insight into relevant situations or sharing stories of his past experiences as a young Guardian. As a result of his devotion to the High Summoner Braska, Auron is idolized in Spira by many aspiring Guardians.
Auron demonstrates his undying loyalty to Braska and Jecht, but beneath the silence, he is outraged by the events of ten years ago. He has become cynical and has little to no respect for Yevon. Despite his usually serene demeanor, Auron harbors feelings of self-loathing. He states to Tidus and Wakka that although they see him as a great Guardian, he considers his past self (like them) to have been foolish and young.
Auron displays some fatherly tendencies towards Tidus and Yuna, due to the promise he made to Jecht and Braska that he would look after their children. Auron is patient with Tidus' childish behaviour and insists that he be accepted as Yuna's guardian, much to the surprise of the others. Tidus reminds him of Jecht, and Auron enjoys pointing out the similarities, much to Tidus's annoyance. Auron chafes at the delays during the pilgrimage, though he ultimately lets the group do as they please, as long as it does not interfere with the journey.
