I like the cyclops, sirens, Scylla and Charybdis from
The Odyssey. Also Grendel and Grendel's mother from
Beowulf. As well as the Ring Wraiths, Shelob, Gollum, the Balrog and the Barrow-wights in the
Lord of the Rings trilogy. Oh, and the killer rabbit in
Monty Python and the Holy Grail. Not that killing people is a good thing, but they were good antagonists (of a sort) in the stories.
Other mythological creatures I like: dragons, griffins, centaurs, the Pegasus, fauns, chimera and the
jackalope.
Not to mention the lovable monsters in
Monsters, Inc. Smitty and Needleman are probably my two favorite (apart from the main characters) in that movie.
"Therefore we do not lose heart. Though outwardly we are wasting away, yet inwardly we are being renewed day by day. For our light and momentary troubles are achieving for us an eternal glory that far outweighs them all. So we fix our eyes not on what is seen, but on what is unseen. For what is seen is temporary, but what is unseen is eternal." 2 Corinthians 4:16-18
"Since the creation of the Internet, the Earth's rotation has been fueled, primarily, by the collective spinning of English teachers in their graves."
