I see Kun saying all of the Jedi, but it's a little hard to believe that all of the Jedi in the galaxy were gathered. They could have at least be more specific to avoid thoughts of exaggeration.
Well, Ulic saying "the Jedi Knights of the Republic are united against you", Kun saying "Even I can't fight the combined might of all the Jedi", the omniscient narrator saying "thousands upon thousands", "combined Force of Jedi Knights", and some Jedi saying he's "receiving a flood of acknowledgments from all Jedi. Thousands of them" was indication enough.
Although, if the omniscient narrator outright stated it was all the Jedi it would've been a lot easier.
And since when does Dooku, Sidious, or any Luke before NJO have the grasp of the force that Kun possesses, let alone the amulet that can supposedly destroy anything in it's path.
If Sidious knew "all techniques", he would know instakilling moves, so why doesn't he use it on Luke? Dooku doesn't exert his Force lightning in every situation where he could have, as well numerous other people that could've used powers a, b, and c in situation x, y, and z, and Traya doesn't use her instakill abilities in every situation that arises as well. Instakilling techniques = just that.
The fact of the matter is, they don't need to, nor does Kun have to use it in the situations of the comic.
My point is saying that saying Kun cause that amulet whenever he pleases is AS ridiculous as saying Kun can use it once.
How is it as ridiculous? Let alone, ridiculous.
Logical deducting there's no reason why he would not be able too, and logical deducting he can use it again.
Since when have his amulet blasts been so impresive?
Perhaps you haven't read TOTJ? If that's the case, just take a look at the pictures IKC posted. Having a DBZ blast that tears through a Sith Wyrm, and temple rock = impressive.
