Melkor (True Form) The Crimson King was eventually erased from existence by Patrick Danville using Roland's blood and a single rose. While the Underrated Melkor could corrupt the very fabric of reality in Tolkien's mythos + bringing down all things to a state of formless chaos. in a way the Crimson King did not for his fictional world/universe, not only that but also The Crimson King was also defeated by main characters in the Insomnia and Black House novels, while all The combined near-omnipotent powers of valar were needed to defeat Melkor.
is there anything else to say?, the winner is clear.
not voted I was expecting more of a tie, cause you can defeat Miraak early in the timeline, but obviously only as the Dragonborn and Hyperstorm I found somewhat similar as in magic and spell casting. Also Sentry is OP with Void, he stomped on the Avengers, mainly including Thor and Hulk.
