Both are High 1-B and speed is equalized.
My money's on Zalgo.
Zalgo will always remain for as long as there is evil, chaos and destruction. Dimentio can't get around that.
Even if, the Void gradually destroys existence whereas Zalgo's Seventh Song blows up all of totality at once.
Zalgo's voice can also blow up celestial bodies and he transcends time and space. Not to mention he horribly outhaxes.
And even mentioning Zalgo's name will get you insta-possessed. Meaning Dimentio would effectively doom himself by simply saying his opponent's name.
So yeah, I'm betting on Zalgo. Please take this to the Forums however.
Likely Zalgo for what wither said. Plus, whatever Dimentio can do, Zalgo can do better.
Agreed.
Might be too late but Zalgo for reasons above
I've been having trouble using the forums.
