Here's some stuff from Kit like I promised.
Kit Fisto snarled, surrendering to the pull of Form I's unarmed techniques. His attack was absolute fluidity, one motion flowing into the next without a wasted effort. Heads cracked, limbs twisted against their joints, and X'Ting flipped howling into the lake. - tCD, CH77.
'Absolute fluidity', 'one motion flowing into the next without a wasted effort'... I think it's safe to say that Kit was a master of unarmed combat.
From the corner of his eye he saw that Kit had made his way almost to Ventress, and what he saw as the Nautolan increased his efforts almost broke Obi-Wan's concentration. His companion was a living, martial hurricane, his body moving in two and three directions at once, joints flexing, unlimited by human vertebral restraints. Who he touched went down. And those who went down, stayed down. Ventress might have gathered a rabble, but the youthful X'Ting were fearless, and fought as if for their lives. Such an onslaught left no time for thought or planning, no room for pretty moves. There was only attack and defense, and precious little time for defense. - tCD, CH77.
1. Kit was moving so fast that his movements almost broke a jedi's concentration.
2. Kit was unlimited by vertebral restraints, he was so flexible that his body was moving in two to three directions at once.
3. 'Who he touched went down', and this was all while unarmed, and it's not like the X'Ting sucked or anything.
Obi-Wan missed the moment, but Kit finally won his way through to Ventress. She raised her hand, and the X'Ting who had harried the Nautolan turned to attack Obi-Wan, leaving her to face Kit alone. Now, finally, Kit drew his lightsaber. Ventress drew a pair of blazing, red blades. She inclined her head, breathing more quickly, lips curling into a smile. "Finally," she said. "Your pleasure," Kit hissed, and went at her. He was like fire, Ventress like smoke. The dance had substance but not form, a blur of light that seemed impossibly fast, unbelievably deadly. The two leapt and swerved, collided and bounced away. Single against double lightblades. Hands, knees, feet, all in a mind-numbing blur.Obi-Wan would have given his right hand to join. Or even to watch such a display. But he had his own worries, his own battle to fight. He struggled with the urge to simply draw his lightsaber and slaughter the X'Ting. His enemies came on and on, struck quickly but clumsily, got in each other's way. Obi-Wan was direct in attack, and as elusive as a breeze. He'd missed the engagement, but suddenly—Kit was down! Wounded and groggy from a kick in the jaw, for the first time Ventress had pierced his guard. Her left-hand saber sliced his arm but as sparks flew he dove away from her left blade, leaning into a glancing blow from her right. Obi-Wan heard the scream but couldn't see the wound's severity. Kit rolled as Ventress came at him, splashing down into the lake. Ventress stood on the dock smiling hugely, arms and legs spread in triumph, laughing in that arctic voice. - tCD, CH77.
1. Ventress had the advantage in the sense that Kit was both injured and fatigued, and she knew the area well. And she was very powerful at this point, Kit losing isn't such a big deal; Obi-Wan would have lost too if Kit hadn't interfered.
2. 'He was like fire, Ventress like smoke. The dance had substance but not form, a blur of light that seemed impossibly fast, unbelievably deadly.', 'Hands, knees, feet, all in a mind-numbing blur.', 'Obi-Wan would have given his right hand to join. Or even to watch such a display.'... While this speaks for both Ventress and Kit, it's pretty clear that Kit's speed was phenomenal.
3. While the battle may seem short due to the small amount of writing, the style that it is written in isn't too descriptive for much of the time, just factually states what happened, so it's anyone's guess as to how long it was.
Anyways, I was going to post more, but I'm too lazy lol. Hopefully that should give you a good idea of Kit's skill.
