@wollfmyth209: 1.I've seen no evidence suggesting that is what occurred at all. Kun ripped his spirit from his body, rendering his body comatose. The spirit was bound to the spiritual realm by Kun's existence.
You continue to claim that there was this big spiritual battle. When really it was just Luke attacking Kun and achieving nothing.
2.It's not just minor TP, he dominates his mind from across the galaxy; keeping him corrupted to boot, and forces him into an action that he absolutely did not want to commit. It goes as far as to describe him as a puppet.
3.That the spirit of Kun was doing all of this, besides channelling whirlwinds through Streen that could launch Jedi thousands of feet into the air and all the rest, absolutely puts him beyond an inferior Luke than the one he'd already faced.
4.Not really, Leia says Kueller's capabilities to wield the Force is greater than anyone else's she has met in years, bar Kun. Keep in mind that Kueller's big deal is that he's constantly feeding on the genocides he is inciting. That's the context to consider. The fight with Luke is irrelevant. Kueller is capable of becoming more powerful than Luke, but not Kun.
