"Listen to my story. This... may be our last chance."
"A city dead for a thousand years. A city I had to see with my own eyes. The end of Yuna's journey. The last chapter of my story."
"It’s true Zanarkand was destroyed, right? A thousand years ago? So it’s just a big pile of rubble now, isn’t it?"
"Let's go to the sea, before the sunrise. The city lights go out one by one. The star fade... Then the horizon glows, almost like it's on fire. It's kinda rose-colored, right? First in the sea, then it spreads to the sky, then to the whole city. It gets brighter and brighter, till everything glows. It's really...pretty. I know you'd like it."
--Tidus describing Zanarkand to Yuna
"Well, I don't claim to know much about Spira. And I probably know even less about the Al Bhed, but... I know Rikku's a good person. She's just Rikku."
"Star player of the Zanarkand Abes. His attacks lack power due to his inexperience with the sword. Speed is his greatest asset. As a child he was a crybaby, and tears still come to him easily."
Tidus is the primary protagonist of Final Fantasy X. The storyline of Final Fantasy X revolves around Tidus, a rising Blitzball star player from Zanarkand. After Sin attacked his hometown, Tidus was transported to the world of Spira. Lost, confused, and seemingly out of place, Tidus meets a newly-fledged summoner, Yuna, and her guardians. Yuna was to set out on a pilgrimage in an attempt to put an end to a terrible creature only known as Sin. Similar to a gargantuan whale in appearance, Sin is the very creature that destroyed Zanarkand. By joining Yuna on her pilgrimage, Tidus hopes he will find his way home.
Tidus is a youthful teen with an upbeat and carefree attitude, as demonstrated at first in the game he is rather childish, however turns more serious when things get hectic. Despite his carefree ways Tidus conceals a troubled past and a more mature and caring persona, this is because of the hardships during childhood towards his father, in fact this is what motivates him to become a Blitzball player, even to the point that he desires nothing more than to return to his world and wrap himself up on it instead of facing his new reality in Spira.
To Tidus' dismay, he has a strong resemblance to his father who at some point denied his position, taking things easy at every time and never worrying about the present situation leaving things for tomorrow, a trait that Tidus despised about his father Jecht. This is pointed out by Auron several times through the game by telling Tidus that he is running away.
For his cheerful personality, it is interesting to note that Tidus is quite sensitive, thinking things through, and even when giving an emotional response to most of his arguments, he tends to give a rational idea, just as he explained to Yuna about his ideas about the Yevon faith, and even when the heroes face the truth about the Final Aeon, Tidus is capable of giving the party a reasonable doubt concerning their fate.
Most of Tidus' personality is related to his father's comments about him, but despite being offensive to Tidus, at heart Jecht was proud of him and his resolve, which in turn made Tidus hate Jecht and think rather lowly of himself, as long since he is not too sure if he is capable of surpassing his father despite his desires. However as the story develops, Tidus grows into a mature nature and selfless persona that even Auron acknowledges and so, Tidus chooses to finish the battle for the sake of his friends, father, and himself to save the world.
