Cerberus's Clique: Monster-Human Alliance
This club is all about promoting peace and understanding between monsters and humans. These kids spend their time passing out flyers that say "Make Love Not War." But it's a little hard for people to take them seriously. After all, when it comes down to it, Cerberus is just a slobbering dog. Nothing Cesar Shmilan couldn't take care of.
Polyphemus (and the Cyclopes)
Polyphemus is the Cyclops to know. (P.S. a Cyclops is a giant monster with one huge eyeball in the middle of his head.) He lives with his fellow Cyclopes on an island in Sicily where they feast on raw flesh. Mmm. Polyphemus is best known for capturing Odysseus and his men in Homer's Odyssey. Here's what goes down: once the Greeks blind the Cyclops and make their escape, Polyphemus calls in a favor from daddy Poseidon. Uh oh. This means years and years of torture for Odysseus (and his men, until they die).
The Minotaur
This angry dude was half-man, half-bull, and spent most of his life locked up in the mysterious Labyrinth on the island of Crete. Like the Cyclopes, the Minotaur was known for munching on a person or two every once in a while. His people-noshing ways didn't last long, though, because the Athenian hero, Theseus, came and stuck him with a sword.
Medusa
This might be the only club where Medusa could be considered "the pretty girl." This lady was a Gorgon, a snake-haired creature so ugly that she turned people to stone whenever they looked at her. (Yeah, that's about as ugly as it gets.) Medusa was killed by the hero, Perseus, who chopped off her head.
Grendel and Grendel's Mom
In the epic Anglo-Saxon poem Beowulf, Grendel is a man-eating demon that lives in the land of the Spear-Danes and attacks King Hrothgar's mead-hall on a daily basis. Every night, Grendel slaughters more Danes and feeds on their corpses after tearing them limb from limb. Although he can't be harmed by the blade of any edged weapon, Grendel finally meets his match when the Geatish warrior Beowulf takes him on in a wrestling match.
Circe
In the Odyssey, Homer (not Simpson, the other one) describes Circe, a beautiful sorceress with a tendency to turn men into animals when they venture onto her island. She is an immortal woman with magical powers who—after turning his men into pigs—convinces Odysseus to stay with her on her island for one year. It might sound like she's got it made, but she's pretty lonely. In fact, Circe vanishes into thin air when Odysseus announces that he's going to leave her and continue his journey homeward. Wah wah.
