See? Keep your head down, say "sir" a lot, and you'll do fine.Luzzu
Luzzu is a non-player character in Final Fantasy X. He is a Crusader of Spira stationed at Besaid along with Gatta, and is one of the first people Tidus gets acquainted with in Spira. Luzzu's dream is to see Sin permanently vanquished, and until that day arrives, he strives to protect the populace with any means necessary. His outcome depends on player choice.
Luzzu has short bright red hair and blue eyes. He leather shoulder pads and a chest plate, but no shirt. He wears sleeves, a green belt cinched with brown cord, and blue loose trousers with X-shaped trimmings on the sides. He wears sandals.
Luzzu is jovial and personable. He nobly dedicates his life to protecting Spirans from Sin, ready to put his life on the line to save others. He is willing to consider means to tackle Sin that are not permitted by the Yevon temple, and seems to take being excommunicated in stride. He inspires other youths like himself to join the Crusaders, and the younger Crusaders like Gatta look up to him as a role model. Luzzu encourages others to take up using machina weapons even if machina-use is banned by Yevon. He struggles dealing with the guilt of the people he encouraged to join getting killed in the fights against Sin.
Luzzu was close friends with Wakka's brother Chappu, and convinced him to join the Crusaders and fight with a machina weapon during the battle with Sin that ended up killing Chappu. When Lulu, Chappu's girlfriend, heard of this, she hit Luzzu.
Luzzu is stationed at Besaid, and meets Tidus when he arrives to the islands. Upon learning of his "amnesia", Luzzu orders Gatta to explain the Crusaders to him. They hint that the Crusaders' final battle with Sin is soon at hand, and that they have been excommunicated from Yevon.
Luzzu and Gatta and the Crusaders leave Besaid the same time Yuna's pilgrimage does. In the Kilika Woods, Luzzu warns Yuna's party of the Lord Ochu sleeping in the forest, and if the party slays the fiend, is impressed and rewards the party with an Elixir.
Shortly before Operation Mi'ihen, Luzzu admits to Chappu's brother Wakka that he was the one who got Chappu to join. Wakka punches him, and Tidus rushes to hold Wakka back.
Tidus's advice to Gatta before the operation decides the fates of Luzzu and Gatta. If Tidus talks to Gatta twice and tells him his place is at the front lines, Gatta is killed. In any other situation, Luzzu is killed. If Gatta is killed, Luzzu is found at Djose Temple. Wakka attempts to convince Luzzu to return to Besaid, but Luzzu shouts at him. Wakka reminds Luzzu that he, too, has lost someone dear to him, calming Luzzu down. If Luzzu is killed, Gatta will say he found Luzzu's body torn in half on the Djose shore. Regardless of whether Luzzu or Gatta dies, Luzzu's dead body, fully intact, can be seen in the hut at the Djose Temple after Operation Mi'ihen.
After gaining control of the Fahrenheit, Yuna and her friends can return to Besaid and find either Luzzu or Gatta training a new group of Crusaders, ever vigilant in the face of Sin. After Yuna's party defeats Sin, either Gatta or Luzzu joins the cheering Besaid villagers, depending on which one survived.
Luzzu is voiced by Ryuuzou Ishino in the Japanese version and John DeMita in the English version.
