considering my alter-ego it's no surprise my personal favorite is the Cosmic Entity / Force of Nature - because they are unique in being horrible (sometimes almost CM status) yet essential parts of creation and remind everyone that while hope and redemption are good things and always exist so too must negative things exist.

It would be a horribly boring universe if there was no "evil", we'd have no reason to do anything or learn.. most importantly, Good can never exist without Evil and vice versa.

Galactus, Death and some versions of the Anti-God concept fit perfectly with the idea of something many dislike, fear and rightfully oppose yet are necessary for existence due to the power of dualism.
