Geryon

"I make it my business to keep informed, darlin'. Everybody pops into the ranch from time to time. Everyone needs something from ole Geryon. Now, Mr. di Angelo, put that ugly sword away before I have Eurytion take it from you."

- Geryon

Geryon (Γηρυόνης in Ancient Greek) is the son of Chrysaor and Callirrhoe and is the grandson of Medusa. He was a fearsome giant who dwelt on the island Erytheia of the mythic Hesperides in the far west of the Mediterranean. A more literal-minded later generation of Greeks associated the region with Tartessos in southern Iberia.

The Battle of the Labyrinth
Geryon owns a two-headed hound named Orthus, which was the brother of Cerberus, and a herd of Apollo's magnificent red cattle that were guarded by Orthus, and a herder Eurytion, son of Ares. Geryon is the owner of Triple G Ranch, with Orthus guarding the ranch. On a tour at the Triple G Ranch they found out that he doesn't care about the animals, only his money. He gave Percy an impossible task; to clean out the stables of carnivorous horses which was also one of the tasks Hercules did. Once Percy completed the task Geryon went back on his deal to let his friends free and the two fought. Percy found Geryon a worthy opponent as he was a challenge due to his three hearts which allowed him to be almost impossible to defeat. Geryon had quoted that he had three hearts, "the perfect backup system." Percy defeated Geryon with a well placed arrow (later revealed to be thanks to Hera) that went through Geryon's sides hitting all three hearts at once, thus killing Geryon.

Personality
Geryon is a cruel monster who is only interested in making money. To this end, he will betray anyone he comes across as long as there is someone with a better offer and tends to break laws that the gods themselves had created (such as killing Apollo's Cattle). He will also break any promise he makes, as long as he isn't held to accepting the terms. Geryon tends to be on the lazy side however, as he will make Eurytion do all the hard work instead of doing things himself. When forced into combat, he relies on his ability to regenerate as long as all three of his hearts are working. This makes him somewhat overconfident in his own abilities and lead to his defeat by Percy.

Appearance
Geryon was often described as a monster with human faces. Geryon had one head and three bodies with a total of two arms. Some accounts state that he had six legs as well while others state that the three bodies were joined to one pair of legs. Although there are some mid-sixth century Chalcidian vases portraying Geryon as winged, it is not known whether Geryon had wings: it seems unlikely. Apart from these strange features, his appearance was that of a warrior.

In the book, he is described as having a normal head. His face was weathered and brown from years in the sun. He had slick black hair and a pencil-thin mustache. He had two very beefy legs, wearing a very large pair of Levis. Each of his chests wore a different colored shirt: green, yellow and red.

Abilities
Being a monster, Geryon is very hard to kill unless facing Celestial Bronze, Imperial Gold, or Stygian Iron. Even with these metals, his ability to regenerate allows him to tire out his opposition instead of fighting them head on. Because Geryon has three torsos, he also has three hearts which means he can not be defeated unless all three of his hearts are destroyed at the same time. Destroying one or even two at a time will weaken Geryon, but he will reform within moments. However without this ability, he isn't very strong and can be easily defeated.
