First Age and earlier ages - Morgoth...only the Valar themselves (with an huge army) were able to defeat him. Second Age - Sauron, he was a tricky bastard and manage to trick pretty much everything....even though his defeat in the Battle of Dagorlad was quite shitty. Third Age - At first I would say Sauron or Saruman but then I think better and they were quite shit so I'm going for the Witch King who was even stronger then some Maia.
