Except Flandre doesn’t need to look at him to kill him.
Plus didn’t he die by looking into a mirror last year?
Ah, a ghost. Well, that’s something Flandre never had problems with before, considering she lives in Gensokyo. xD
Your logic = fails
I’m going with the shadowy councils old powers in this fight so here...
If Nyx were to happen to fight her after he absorbed the core he would use his time manipulation skills to stop or slow down time (depending on luck) then he’d use his soul reaper technique on her which is basically overkill. She can’t escape it either, I mean it’s a possibility but when Nyx uses time manipulation she’s bound to die.
And there’s something more powerful than Chuck Norris: Bruce Lee.
Not really...I mean:
Sakuya manipulates time and Remilia>Sakuya
And Flandre=Remilia or Flandre>Remilia
So then it’s definitely fair to say that at least Flandre>Sakuya.
Plus that’s assuming Flan Flan has anything remotely close to a soul. xD
Well Nyx can bend time in his favor any way he wants to. He can even manipulate time so that he could move at light speed. And even if that doesn’t work, Myth would just hide and charge up his darkness and light purification power then release it at Flandre, and if that doesn’t even work Serene could just toy with a bunch of realms effecting each ones outcome which will eventually follow up to the destruction of Flandre’s realm.
