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 soon 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 for this is that 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, which despite being offensive to Tidus, at heart Jecht was proud of him and his resolve, which in turn make 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
Tidus is the classical Warrior character of the party and uses basic Swords and Shields during battle. He also can be considered part Time Mage because he can cast spells like Haste and Slow. His stats are fairly normal for an allrounder: he lags behind Auron in terms of strength (explained in the game as his “inexperience with the sword,” if you cast Scan on him) and defense but makes up for it with high Agility, Evasion and Accuracy growth, allowing him to easily dispatch the speedier fiends. Tidus begins the game with no commands but will quickly learn the abilities Cheer, Flee, and Delay Attack, which are very helpful in the early battles. His Overdrive is Swordplay which is diffrent techniques all revolving around difficult topull off sword techniques
Throughout the game, it is very noticeable that Tidus eventually matures, changing from a somewhat self-centered, outspoken athlete to a selfless hero. This theme is also hinted in the flashbacks of when Jecht helped defeat Sin in his own adventure, as well as in a conversation between Yuna and Tidus, where Yuna states that defeating Sin and bringing happiness to Spira makes any price worthwhile. At the game’s conclusion, Tidus has obviously come around to her way of thinking. (Ironically, during the events of Final Fantasy X-2, Yuna expresses a clear opposition to sacrificing lives, indicating that she had taken up Tidus’s way of thinking.)
Because he is never directly referred to by name in any audible dialogue, the pronunciation of his name among fans is sometimes unclear, although the expected Japanese pronunciation should be Tee-das/Tee-dusu. This was confirmed in dialogue from Kingdom Hearts, which featured him in an unusual cameo, and was also confirmed in an interview with James Arnold Taylor, who did Tidus’ English voice. Unfortunately, in Kingdom Hearts II, although he doesn’t appear, Selphie mentions him, pronouncing his name as Tie-dus, confusing the issue further. Though ostensibly unrelated to either, the pronunciation of his name among fans may also be affected by its resemblance to the English word tide and the given name Titus. However, in the English release of Dissidia Final Fantasy, all characters in-game refer to him as “Tee-dus.”
Tidus is considered an interesting, unconventional hero and a refreshing break from the clique of broody role playing game protagonists (Fans often specifically reference Final Fantasy VIII‘s Squall Leonhart, as well as Final Fantasy VII‘s Cloud Strife), as his personality at its core is friendly, playful, and good-hearted (not unlike Final Fantasy IX’s Zidane Tribal). Taylor reprises the role of Tidus in the spin-off Final Fantasy X-2 as well as that of the antagonist, Shuyin.
