In Greek mythology, the Titans were a race of powerful deities who were overthrown by the Olympian gods when they came to power. In Disney's Hercules, the Titans are the tertiary antagonists, portrayed as four elemental monsters who terrorized Ancient Greece. They were the physical manifestation of the element they controlled. These "Titans" were original creations for the film. Hercules: The Animated Series, which expands on the Greek mythological setting and addresses many of the movie's inaccuracies and omissions, featured Titan characters from actual Greek mythology.
The Muses tell the legend of the Titans through their song The Gospel Truth. The Titans were the rulers of the world (or at least Greece) when it was first new and they caused mayhem and destruction wherever they went. In the animated series, it was also explained that they were led by their king Kronos. Then along came Zeus who used all his power to unleash a mighty thunderbolt that would imprison them beneath the seas of Tartarus where they would remain until the next planetary alignment. They were the children of Gaia and Uranas.
Hades plotted to release the Titans to overthrow Zeus and rule the world but was warned by the Fates that his plan would fail if Hercules intervened. After getting Hercules to surrender his superstrength in exchange for no harm coming to Megara, Hades frees the Titans, who were hungry for revenge against Zeus. The Titans begin a path of devastation, before being told by Hades that they're headed in the opposite direction of Mount Olympus. They overpower the gods in quick succession. However, he sends the Cyclops to take care of Hercules in Thebes. Despite not having his strength, Hercules is able to use his brains, tying the Cyclops' legs together, causing him to fall off a cliff. In the course of the battle, Hercules regained his strength after Meg was mortally wounded, and proceeded to battle the Titans and free the gods. He proceeded to throw the Titans into space, where they are destroyed in a spectacular cosmic explosion.
In Olympus Coliseum, the Rock Titan appears as a boss and the final contender for the Hades Cup, and is defeated by the teamwork of Sora, Donald and Goofy. The Ice Titan also appears as an optional boss in the Gold Match, where Sora has to defeat him alone.
The Mountain King: A two-headed Titan made completely out of rock. He ripped through the gates of Mt. Olympus, and is the physical manifestation of earth. He appears to be a large two-headed boulder creature with glowing red eyes. The inside of his mouth is red as well. Since he is very large and heavy, Lythos has the ability to stomp on the ground and cause massive earthquakes.
The Lurker: A skeletal Titan made completely out of ice. He teamed up with Pyros to engulf Zeus into the Earth. He is the physical manifestation of water.
The Lord of Flame: A blob-like Titan made completely out of lava. He teamed up with Hydros to engulf Zeus in the Earth. He is the physical manifestation of fire.
The Mystic Voice: A tornado-like Titan with tornado arms, red eyes, and a red mouth. He was captured by Hercules to suck up the other titans and destroy them. He is the physical manifestation of air.
A fat, pink Cyclops-like creature that Hades had attack Hercules instead of Zeus. During his assault on Thebes, Hercules was able to defeat it, just before it knocked over a pillar that crushed Meg. He is the physical manifestation of ether. He was voiced by Patrick Pinney.
A muscular human-like Titan that was cursed by the Gods to forever hold up the sky at the Edge of the World. He constantly tries to trick people into switching places with him.
The former ruler of the universe (or at least the country of Greece) and father of Zeus, Poseidon and Hades. When he found out one of his children would overthrow him he tried to swallow them whole, however he was defeated by Zeus and as a last act he created the Kronos Stone. The stone would place any god that comes near it into an eternal sleep. Hades hoped to use the stone to overthrow Zeus. Kronos was sealed in an unknown region of Tartarus.
A kindly human-like Titan who long ago stole the gift of fire from Mount Olympus and gave it to humanity so they could improve their lives. However, Zeus was angered by Prometheus' disobedience and so he chained him to a mountain in Tartarus where a giant eagle would come each day to feast on Prometheus' liver, which would regenerate after each day. Hercules freed him after he realized the injustice Prometheus suffered.
He is a powerful giant said to have a hundred hands. Despite being called the "Hundred Handed One," he only has two visible arms. The reason he is called this is because he can sprout over a hundred hands from any terrain. Depending on the terrain that the hand is summoned it will take on the element of the terrain such as if it is summoned in a body of water, a rocky terrain or on a plant it will take on the attributes and physical appearance of the terrain. He is also an open comic book fan, and a big follower of Miklos. He's based on the Hecatoncheires of Greek mythology, specifically Briareos.
Also known as "The Father of All Monsters", he is a red, five-headed, dragon-like Titan who long ago was sealed away by Zeus under Mount Etna. He was accidentally freed by Hercules while he was fighting Typhon's wife Echidna. He seems to suffer from chronic headaches due to all the years he spent under Mount Etna.
Also known as "The Mother of All Monsters", she is the wife of Typhon. Echidna had a recurring role in the series, and was typically seen as an obsessive and doting mother to her various children, who one-by-one were defeated by Hercules.
Rhea - The wife of Kronos and mother of Zeus.
It is unknown whether the Titans that appeared in the film (including the Cyclops) are actually deceased, since Titans are basically deities. Though perhaps only their bodies were destroyed.
In the original myth, Titans are long-distant relatives of Hercules and Olympian Gods.
