American comics: This villain is evil in a good way

Mark always found the Marvel universe strange, with its constant stream of unscrupulous time travelers trying to return to the present and kill him, the main villain. Fury called him a born evil brat, manipulating power and hearts from behind the scenes; even Wolverine called him an enemy of all humanity, a destroyer of free will. But Magneto called him the King of Mutants, Nebula called him the Lord of Tran, the Collector called him the End Producer of the Universe, and the Watcher revered him as the only one. Having just escaped Lolita Island with his friends, Mark didn't care about those ridiculous titles; he only cared about how to survive in this country's death row.
