You're putting Lich King, Malfurion, Sephiroth and Ganondorf against an supposed planet destroyer.
You then in the list include an entity that dwarf planets so much that it's ridiculous and is supposedly virtually indestructible in the sense that his body consist of energy
Dark Khan lack feats adequate enough to pose a threat and I know nothing about Trance Kuja.
when i said innocents i didnt mean lich king . she stopped some powerful attack, that her creator thought would destroy her, with one hand. plus she can do an even stronger version of that attack.
If she's not ready to destroy regions (Which will contain innocent), she'll have a hard time bringing Lich King down. He won't have the firepower to bring her down, but he surely has the means to survive.
KOS-MOS has never destroyed one galaxy. Except in a noncanon "what-if" scenario, where she clashed with what is basically God in Xenosaga. Big guess who it is that caused the vast majority of the blast.
She has never shown that kind of power in the plotline to my knowledge.
Anyway, Dark Khan and Pyron completely wreck her with the utmost of ease, and she utterly annihilates the rest.
that is also how he was created. some funny ass wormhole reaction to lasers and lightning the result was a pile of shit in more than one way. although the joker was great in that game
