Ronso youth fearless. Go to battle with Guado!
Garik is a young Ronso who survived the massacre of his race at the hands of Seymour Guado shortly before the defeat of Sin and the start of the Eternal Calm. Because of Seymour's actions, Garik seeks revenge on all the Guado and leads a rebellion, against the wishes of the new Ronso Elder, Kimahri. Yuna can steer the path of the Ronso by speaking to them and answering their concerns with either support, anger, or indifference.
Garik climbs Mt. Gagazet hoping to get guidance from the mountain. Yuna follows and tries to convince him that slaughtering the Guado will not change anything, and she will fight him if need be. Garik agrees that if Yuna can defeat him then he will rethink his plans.
The way the earlier conversations go will alter the fight that the Gullwings have with Garik at the Gagazet Prominence. If the party decide to not interfere with the Ronso troubles, Yuna will learn Garik has led the Ronso Youth to destroy the Guado hiding in the Macalania Woods. If the Gullwings sway Garik, he seeks Kimahri's aid and the two will fight. Kimahri is victorious and explains to Garik that he must not seek Kimahri for answers, that every Ronso must find their own path in life.
Garik is an optional boss, fought on Mt. Gagazet in Chapter 3. Mighty Guard can be learned from him as a Blue Bullet command. He also appears in the Fiend Arena as an opponent in the Youth League Cup, alongside two Ronso Youths (although Mighty Guard cannot be learned, as he is immune to confusion).
In the HD Remaster version, Garik can be captured by using an SP pod (humanoid) at Mt. Gagazet (chapter 4/5). Aside from the Attack command, he is recruited knowing MP Blowout, which does large MP damage to an enemy (often up to 9999 at higher levels). He can also learn Mighty Guard by having Protect or Shell cast on him, although, but it cannot be learned as a Blue Bullet this way.
