Kiva is a strong fighter and he is quite fast as well. He can engage in both long range combat and close quarters although the latter is certainly his specialty. His hand to hand skills are far better than Clefairy’s, but she has many more attack options than he does. She can use attacks like Hyper Beam and has many stat boost abilities as well. The fact of the matter is that catching Clefairy and tagging her with any attacks will be quite difficult in the end. Kiva’s speed won’t be enough to dodge Clefairy though. Clefairy wins.
