5. Three Forms:Sauron took forms of a werewolf, a serpant, and a vampire during his battle with Luthien and Huan during First Age of Middle-earth.
4. Annatar:One of Sauron's most significant guises since it was via this shape that he tricked Elves into creating powerful rings.
3. Sauron's Armored Form:This form of Sauron was shown in the Lord of the Rings films, drawing influence from Tolkien's writings in which he characterised Sauron as a massive armoured figure.
2. Shadow Form:Although the loss of Sauron's Ring destroyed his physical form, the Dark Lord's essence lived on until the Third Age.
1. Great Eye Form:Sauron's most recognisable look was that of a massive blazing eye. As a symbol for his orcish troops and a thing that shows up in visions.
