The Cyclopes were gigantic one eyed monsters seen on the Odyssey. The three that represent thunder, lightning and the lighting bolt are named Brontes, Steropes, and Arges. They were born to Gaea and Uranus. Gaea is the Earth goddess. She mated with her son Uranus, the sky god and first ruler.Together they produce twelve of the Titans. The Cyclops are also the first smiths.When Cronus came to power he imprioned the Cyclops in Tartarus. Cronus is the ruling Titan who came to power by castrating his Father Uranus. His wife was Rhea. There offspring were the first of the Olympians. To insure his safety Cronus ate each of the children as they were born. This worked until Rhea, unhappy at the loss of her children, tricked Cronus into swallowing a rock, instead of Zeus. When he grew up Zeus would revolt against Cronus and the other Titans,also known as the elder gods ruled before Zeus, defeat them, and banish them to Tartarus in the underworld. The titans were released by Zeus and fought with him agaisnt the Titans. As a reward for their release the Cyclopes gave Zeus his weapons of lightning and thunder. They continued as his workers at Mount Olympus forging his thunderbolts. Argos was killed by Hermes while he gaurded Io for Hera. Apollo killed at least one of the Cyclopes to retribution for Zeus killing his son Aesculapius.
Hecatoncheires means "hundred handed". They were gigantic and had fifty heads and one hundred arms each of great strength. There were three of them: Briareus also called Aegaeon, Cottus, and Gyges also called Gyes. They were born to Gaea and Uranus. Their mutual hatered of Uranus caused him to force the Hecatoncheires back into Gaea's womb. This parcipatated Gaea's rebellion against Uranus. When Cronus came to power he imprisoned the Cyclopes in Tartarus. The were released by Zeus and fought with him against the Titans. They were able to hurl huge boulders as many as a hundred at a time against their opponents. One of them, Briareus, served as Zeus's bodygaurd.
The giants were generated from Uranus blood resulting from his castration by Cronus. They became powerful enough to try to unseat Zeus and the Olympians early in their rule. When the gods won they imprisoned the Giants in Tartarus.

Gorgons are These are female monsters with snakes for hair. Their faces are so ugly that any man that see the face will turn to stone. Oddly the three gorgons have very different origins. Stheno and Euryale were born as gorgons from Phorcys and Ceto. They are immortal. Medusa was not.
Medusa began life as a girl so lovely she made Athena jealous. Such beauty turned Poseidon's head. He seduced the girl but, unfortunately for her did so in one of Athena's temples. Such an affront to Athena would not go unpunished particularly by one already in ill favor. So Medusa was turned by Athena into a gorgon. Since she started as human she remained mortal. As if this were not punishment enough, Athena later helped Perseus hunt her down and kill her.
When Perseus cut her head off Pegasus and Chrysaor, her children by Poseidon, sprang forth. Drops of her blood fell into the Libyan desert and turned into snakes. Later one of these snakes killed Mopsus. After Perseus left with her head Athena took charge of what was left of her body. She flayed off Medusa skin and made it into her trademark Aegis. She two drops of the blood to King Erichthonius explaining that one would cure disease and the other was a deadly poison. She gave a lock of the hair Heracles hidden in an urn.
