While it's a different continuity, there's Darknite/Nitemare, the guy is so strong that in order to summoned all egyptian items had to be gathered or sacrifice yourself to him in the computer world, he is the Creator of the Shadow Games, can turn people into cards and burn said cards
He wanted to conquer the world by presumably invading it with his army of real strong monsters which can include Obelisk/Slifer (Osiris)
Difficulty wise, he is only behind Seto 3 and his double Ultimate White Dragon
Only Yugi and Kaiba were able to defeat him twice
