It would be tough, but Sadow could possibly emerge victorious, since its likely that whatever Kun has, Sadow will have more of, and DN Luke just isnt on par with Sadow, although them together can take him out.
Sadow takes it more often than not.
Btw Kressh and Sidious take it more often than not as well.
It depends how fast Sidious dies to Luke in comparison to how fast Kun dies to Kressh.
If it was DN Luke vs Ludo Kressh and DE Sidious vs Exar Kun, Sidious wouldn't die extremely quickly, he would die and that is perhaps how Kun/Luke team can win. However if it was Kressh vs Kun and Sidious vs Luke, the end result would be Kressh vs Luke, in which the outcome would come out to be Kressh winning more often than not.
Probably so but most people here put Kun on par with DN Luke, so it doesn't matter which one Sidious faces because each one could equally curbstomp him quicker than Kressh takes out one of them. Then again Kressh could swing his sith sword as quick as Luke or Kun can swing their lightsaber, so he's going to push back whoever he's fighting with that much force.
Kun is not really on par with DN Luke, the only person who believes that is IKC, and most of us cant argue with him, so we just agree with him.
None of what Kun did were of his own inventions, they all originated from the Ancient Sith, and Kun's power is just a shadow of what the Ancient Sith were, however Luke, can perhaps have a better chance in contending by surprising the Ancient Sith with unheard of powers, but nevertheless the Ancient Sith would curbstomped Luke.
Whereas i dont give Kun much of a chance against the Ancient Sith, i hardly think that Kun will be able to successfully turn the remnants of the Ancient Sith knowledge against its creators. Adding on that, the Ancient Sith possesed immense power that surpassed Kun by miles.
Well yeh, Luke would defeat an Ancient Sith Apprentice, he might be able to contend with Kressh, but less likely against Sadow and a 0 chance against Ragnos, unless its a Ragnos on his deathbed.
