Harry Potter

Sauron is the primary antagonist and titular character of J. R. R. Tolkien's The Lord of the Rings.

In the same work, he is revealed to be the same character as The Necromancer from Tolkien's earlier novel The Hobbit. In Tolkien's The Silmarillion (published posthumously by Tolkien's son Christopher Tolkien) he is also revealed to have been the chief lieutenant of the first Dark Lord, Morgoth. Tolkien noted that the "angelic" powers of his constructed myth "were capable of many degrees of error and failing", but by far the worst was "the absolute Satanic rebellion and evil of Morgoth and his satellite Sauron."

Grover Underwood is a fictional character in Rick Riordan's Percy Jackson and the Olympians series. He is a satyr, a mythological Greek being that is half goat and half human. He has the upper body of a human and the legs and horns of a goat. He wears jeans or false feet with sneakers when he wants to look like a human. His horns are usually hidden by his curly brown hair, although they eventually grow too tall for him to hide them and must wear a rasta cap to hide them. Despite being 32 Grover looks and acts like a teenager this is because satyrs mature half as fast as humans.
