Lulu

Lulu is a playable character in Final Fantasy X. She is one of Yuna's Guardians and, next to Auron, is the wisest and most mature of them all. Lulu grew up with Yuna in Besaid. She and Wakka think of Yuna as a younger sister. Lulu's stoic and self-possessed nature makes her seem insensitive at times. She specializes in the art of Black Magic, using various dolls to help cast powerful spells. She is instrumental in helping Tidus adjust to the world of Spira, although she does not fully believe his claim of being from Zanarkand.

Appearance
Lulu deviates from the traditional Black Mage look like that of Vivi Orunitia. She is instead dressed in an outlandish low-cut fur-lined black dress that prominently displays her breasts. She wears a huge collection of interlocking belts below the waist. She also wears several accessories such as some necklaces and earrings. Her hair is tied up in a knot at the top with long braids dangling from it. Her manner of dress is also completely different from that of other residents of the tropical isle, and the cultural distinction implied by her clothing and appearance are never explained. The only known citizen of Spira who looks or dresses anything like her is Paine, who is introduced in Final Fantasy X-2.

Final Fantasy X
Lulu — born on the island of Besaid, where she grew up with Wakka, Yuna and Wakka's younger brother, Chappu — is often stern and scathing (particularly to Wakka), and doesn't smile very often. However, she is nonetheless kind-hearted and caring toward others. She is also highly intelligent, and is one of the few Yevonites who easily questions the Yevon religion on objective terms. Nonetheless, she is still shaken by the hypocrisy of the Yevon order, though she adjusts to this reality faster than some of the other former believers in her party. Before becoming a guardian to Yuna, Lulu guarded two previous summoners whose pilgrimages abruptly ended before reaching the Zanarkand Ruins. The pilgrimage of the first summoner Lulu guarded, Lady Ginnem, was cut short by her unfortunate death in the Cavern of the Stolen Fayth, taking place during an attempt to acquire the Aeon Yojimbo. This event still troubles Lulu's memories, but when Yuna and company detour to the valley where the cave is located, Lulu decides to follow and face her painful memories. At the back of the cave, the group meets the unsent form of Lady Ginnem, the human personality she once held all but completely buried in enmity for the living. Lulu felt that she must fulfill a last duty to Ginnem as a guardian in ensuring that her spirit would depart to rest peacefully on the Farplane. After fighting and defeating Yojimbo — the aeon having been summoned by Ginnem — Ginnem's spirit departs for the Farplane. The pilgrimage of Father Zuke — the second summoner she served as guardian to, together with Wakka — did not even get that far. It ended at the Calm Lands, as he chose not to continue his pilgrimage, a decision many summoners make when they reach those plains.

Lulu is very protective of Yuna and also respectful of the decisions she makes. When Seymour Guado proposes marriage to Yuna, Lulu is supportive of the union, as it will give the people of Spira some happiness as well as furthering relations with humans and the Guado. While Tidus is against any marriage, Lulu cryptically responds that she would like for Yuna to marry for love, but not for her to marry the one she loves, knowing full well who he is.

Prior to his death at the hands of Sin, Lulu had been romantically involved with Wakka's younger brother, Chappu, and his passing left a deep wound in Lulu's heart. However, Wakka and Lulu find love for one another, and six months after the ending of Final Fantasy X, are wed to one another. In Final Fantasy X-2 Lulu is pregnant with — and gives birth to — Wakka's child, a boy whom Wakka names "Vidina" (the Al Bhed word for "future").

Lulu in Battle
Lulu is a Black Mage, and thus her physical attacks are initially weaker than the other characters. Instead, she relies on magic attacks and her weapons consist of Dolls which are based on classic Final Fantasy creatures: Mog, Cait Sith, Moomba, Cactuar and PuPu. Lulu also has the best Evasion by far in the game.

Lulu's Overdrive is called Fury. It casts a barrage of spells on the target. To successfully execute Fury, the Right Analog Stick must be rotated 360 degrees. More spins add more castings. Mostly all of the Black Magic spells can be cast. These spells cannot be evaded, protected against, or prevented in any way and do not cost MP, but do significantly less damage than a normal casting of the same spell. Lulu cannot cast a spell with Fury until she learns it in the Sphere Grid.
