Kimahri did always strike me as weak. The only reason I used him was to gain access to ultima and use a black magic sphere / friend sphere to transfer the skill to Lulu. Same for Holy. Other than that, he never saw the light of day.

Kimari ia needed he helped me fight and defeat some really tough monsters through out 10.

I'd consider him worth training up. Okay, so he doesn't have a set path... but he starts out with a good offensive, so I always take that into account by either putting him on Wakka's or Lulu's sphere grid.

However I normally ensure that he lands on Auron's at some point, primarily for the Biran and Yenke fight, in which I find more use in physical strength over magic. Even though Demi is pretty useful in such a fight...

His Overdrives were pretty damn good, too. I loved using Fire Breath, Nova, and Stone Breath.

I don't think I'd ever consider him useless. I actually enoyed trying to get all his Overdrives.

I really don't use Kimahri all that often. Ok, so, he CAN be good in combat and he CAN be pretty darn useful depending what path you chose for him (W. Mage, B. Mage, Thief, Warrior ect...) and he does have some pretty spiffy overdrives if you can be bothered to get off your ass and get them all (I've just done Yunalesca in my 4th game and I have all overdrives so far except Supernova, suprisong really since I don't use him that much. ) but KImarhi is just one of those characters that I fail to use in battle that often (I swear, I have one in EVERY multi-character game. XD).

Role wise, I thought Kimahri was a great character, I loved his harshness towards Tidus at the begining and his comforting, proctiveness towards Yuna. And don't forget how cute he looked when he smilied! XD

Well sure, just like no one would be caught dead using Vincent after level 50 or so, but I still admit to using him in my main party my first time through FF7.

I liked Kimahri as a storyline character, yep. But it just always seemed like there was a better choice when it came to combat.

Of all the three times i beat the game i have never once leveld him up. I had to use him for one boss battle and that was because they mad me use him ^^

well if you spent that much time with him he would be worth it then. But i would never use him
