In Final Fantasy X
, Kimahri is a Ronso
from Mount Gagazet
. His horn was broken during a childhood fight with fellow Ronso Biran
. He is a guardian
of the summoner Lady Yuna
, and accompanies her on her pilgrimage
to all of the various temples
, 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.
