1. Poseidon
A jumbo-sized Poseidon rises from the sea before transforming into a less-conspicuous human size in the early scenes of the movie.
2. The Fury
Usually encountered in a group, Percy first gets the hint that something odd is going on with him when his substitute teacher transforms into the winged, toothy Fury in a back room of the Metropolitan Museum of Art.
3. Chiron, the Centaur
Apparently wheelchair-bound teacher Pierce Brosnan continues his involvement with Greece, though in a very different role from what he played in "Mamma Mia the Movie". Here his wheelchair conceals his horse legs and body.
4. Perseus
Percy's "real" name is Perseus, a famous hero of Greek mythology who - spoiler alert! chops off the head of <a href="http://gogreece.about.com/cs/mythology/a/blmythmedusa.htm:>Medusa</a>.
5. Athena
Anabeth, a vigorous young girl who is an able fighter, is said to be the daughter of Athena, goddess of wisdom. However, in traditional Greek mythology, Athena was usually considered to be chlld-free. But she did have a lesser-known aspect called "Sweet Athena", who may have been more open to a loving relationship which could result in a child such as Anabeth. But this is one of the more major deviations from classical Greek myth in the Percy Jackson universe.
6. Pan and Satyrs
The Greek god Pan is a sort of super-satyr; Grover, Percy's appointed protector, is half-goat and very interested in the daughters of Aphrodite - not inconsistent with the ancient Greek myths, where Aphrodite is sometimes shown warning off a satyr by whacking him with her sandal.
7. Zeus
I have a hard time imagining Zeus misplacing his thunderbolt, but stranger things have happened in Greek mythology.
8. Hermes
Hermes is a multi-purpose god in Greek mythology. Spoiler Alert: His son Luke takes after his father, who was, among other things, the patron god of burglars.
9. Aphrodite
Aphrodite is only glimpsed in the movie, but a large group of her enticing "daughters" frolic at Camp Half-Blood.
10. The Minotaur
This giant beast is half-man, half-bull, the result of an engineered liaison between Pasiphae, the wife of King Minos of Crete, and a bull that Minos was given to sacrifice to the gods. He liked the bull too much to sacrifice it, and Pasiphae was made by Aphrodite to really, really like the bull as a way of punishing King Minos's impiety in failing to sacrfice it. The maneating Minotaur was the result.
