Tidus is a minor character in the Kingdom Hearts series, originally from Final Fantasy X. He is one of the residents living in Destiny Islands and is part of a trio including Selphie and Wakka. He is thirteen years old during the events of Kingdom Hearts and Kingdom Hearts: Chain of Memories and fourteen during Kingdom Hearts II.
Tidus is a friend of Sora, Riku, and Kairi, and is a resident of the Destiny Islands, spending most of his time with Wakka and Selphie.
In Sora's 'Dive to the Heart', Tidus appears in the Destiny Islands area along with Wakka and Selphie. His question, like the other two, determines Sora's leveling pace for the rest of the game.
Q: "What are you so afraid of?" Sora can answer the question in three different ways. Either A) getting old, B) being different, or C) being indecisive.
Later, on Destiny Islands, if Sora talks to him, Tidus will offer to duel Sora. If Sora declines the fight Tidus will have multiple possible remarks; the most notable being that he and Wakka are working on some type of underwater ball game; which is a reference to Blitzball from Final Fantasy X.
If Sora loses a practice battle with Tidus on the second day in the Destiny Islands, Tidus performs his victory pose from Final Fantasy X by tossing his sword upward then catching it before swinging it to his side.
Tidus's fate after the Destiny Islands' destruction is unknown, but he reappears on the island just as he left once Sora defeats Ansem and the worlds are restored.
Kingdom Hearts: Chain of Memories
Tidus appears with Wakka and Selphie in both Sora and Riku's stories as part of the memory-based Destiny Islands in Castle Oblivion. Some time after Sora goes to sleep, the real Tidus is seen playing with Wakka and Selphie on a beach while Kairi is facing the Small Island.
Kingdom Hearts II
He does not appear in Kingdom Hearts II; however, Selphie mentions that he and Wakka are "All wrapped up in their ball game," which furthers the blitzball reference from the first game.
Kingdom Hearts coded
Tidus makes a third appearance, this time as a data version of himself, alongside Wakka and Selphie. He appears on the data version of Destiny Islands, collected from memory of before it was destroyed by the Heartless. He was searching for the reason behind the blocks all over the island. He saw the Black Coated man right near the waterfall, but doesn't tell Sora of the man's whereabouts until Sora defeats Tidus.
Tidus in Kingdom Hearts looks like a much younger version of his Final Fantasy X appearance, albeit with a simpler outfit. He wears a small, short-sleeved shirt with white sleeves, yellow hems yellow center, and white lining around the center. This shirt is open just like it is in Final Fantasy X, exposing Tidus's chest. His hair is sandy blond, worn in the same style as his original incarnation, and his eyes are blue. For an unknown reason, Tidus has a small scar on his right cheek that was not present in his original game. Tidus's unique, navy pants have uneven legs, with his right pant leg reaching just past his knee, and his left reaching to just about mid-thigh.
His sprite in Kingdom Hearts: Chain of Memories reverses this. The left leg has a diagonal zipper on it, presumably a pocket, and he wears a black fanny pack with the pouch facing forward, showing another diagonal zipper. Tidus wears sandals with a coloration vaguely reminiscent of his original boots; yellow and black, with the addition of pale green. His Zanarkand Abes necklace is not present, nor is any reference to the symbol on his clothing. Tidus carried a wooden stick in lieu of his famous Brotherhood sword, though he has the same battle stance and victory pose using the stick as he did with his sword.
Tidus is the main protagonist of Final Fantasy X. He was seventeen-year-old Blitzball player from his home Zanarkand, playing on the team of the Zanarkand Abes. However, when a man named Auron appears, Tidus finds his hoem begin attacked by a creature called Sin. Tidus finds himself washed up on a shore in a new world called "Spira", a thousand years in the future. He travels with Summoner Yuna, who wants to follow in her father's footsteps and destroy Sin and brig the Calm. Throughout the game, Tidus learns more about his father, Jecht's, past, deals with his increasing love for Yuna, and the implications of her pilgrimage. Tidus is an exceptional fighter with superb athletic abilities and affinity for swimming both above and under water due to his expertise on the playing field during the futuristic sport, Blitzball. Tidus uses longswords, and his attacks are one-handed and quick.
- Tidus's model is used for one type of generic non-playable character in Kingdom Hearts.
- Unlike the original Kingdom Hearts, which pronounced his name with a hard E sound (tee-dus), when Selphie mentions him in Kingdom Hearts II, she says his name with a hard I sound instead (tie-dus). It is noted that the katakana of his name, though romanized as Tidus even in the Japanese versions of Tidus's appearances, is read as (tii-da) (ティーダ Tīda), and is derived from the Okinawan word for "sun". As the Japanese "ィ" is pronounced like the English "E", it suggests that the Kingdom Hearts pronunciation (tee-dus) would be closer to the Japanese equivalent. Additionally, Dissidia Final Fantasy and interviews with Tidus's voice actor confirm it as "Tee-dus", indicating that his name pronunciation in Kingdom Hearts II may have been an error.
- Tidus & Yuna have a romantic relationship in Final Fantasy X and its sequel, but in the Kingdom Hearts series, they never encounter each other, and it's unknown if this will ever be touched upon.
