>>38018406Sauron was at his most powerful when he participated in the creation of the world. Since then, everyone but Eru have been losing power level like crazy, especially the bad guys.
Now, Third Age Sauron, even without the One Ring, could control the dead enough to get called "The Necromancer".
You also have to take into account that if it's after he gave the rings, but that he's still at his best, it means that he's still Annatar, Lord of Gifts and sexy guy extraordinaire, and wasn't yet pwned by God McExpy in person.
We also know that after the fall of Numenor, Sauron was good enough to wrestle to death Elendil and Gil-Galad, mightiest fighters of Middle Earth at the time, at once, and the mighty sword Narsil was broken in the process.
Logicaly, Sauron at his best would be even greater physicaly.
Also, since the Lich King is a bad guy, /tg/'s favorite pretty boy isn't bound by the "evil lose" rule of Tolkien's work.
All in all, I'd say Sauron would win. And become the next Lich King after erasing the hive-mind thing
