In
Final Fantasy X, Kimahri is a
Ronso from
Mount Gagazet. His horn was broken during a childhood fight with fellow Ronso
Biran and
Yenke. He is a
guardian of the
summoner Lady Yuna, and accompanies her on her
pilgrimage to all of the various
temples of
Yevon in
Spira, as she tries to achieve the
Final Aeon and thus defeat
Sin.
His celestial weapon is the Spirit Lance, which may be obtained by completing the Quactuar Quest on the Thunder Plains. Once you have done this, you need to Saturn Crest and Saturn Sigil to give the Spirit Lance its full potential.
I personally like Kimahri - he doesn't talk much, but he is a pretty decent fighter. Plus, if you use his Lancet ability, you can learn the special attacks of various fiends, such as Stone Breath and Mighty Guard, to name just a few.
