Jaden's TK was able to stagger Mother, multiple times.
A living, sentient, Rakatn space station.
He was also able to hold off a clone of himself and Kyle Katarn.
The Kyle Katarn clone was able to destroy an entire hospital, and kill everyone inside, with a single blast of TK.
I'm sure he loses in sabers, but his TK game is amazing.
I know Kol wasn't in an ideal position to fight it off, but I can't remember if he had actually been wounded beforehand. Still a good feat for Nihl, and even better for Wyyrlok. And even better still for Vong Krayt, whose skills in telekinesis and Lightning "far surpassed those of any Sith in his Order". Which is good for Muur, who easily caught Krayt's Lightning with one hand 🙂
