Atlas

The General is later revealed to be the titan Atlas is Kronos' ally and is in charge of recruiting monsters for the Kronos' cause. While Kronos is still regenerating inside of his Sarcophagus, the General seems to be in charge of the army. He was the consort of Phoebe, a fellow Titan. He is also the father of Zoë Nightshade, as well as her sisters, the Hesperides Nymphs.

Early Life
Atlas was a part of the second generation of Titans. He was one of three sons born to Iapetus and the Oceanid Clymene. When the first war with the Titans he was made the General of the Titan Army.

Atlas was the father of the Hesperides by Hesperius, Pleiades by Pleione, and Calypso, Dione, and Maera by one or more unspecified goddesses.

When the gods won the war Zeus sentenced Atlas to hold the wieght of the sky (Uranus) on his shoulders forever.

Search for the Ophiotaurus
In The Titan's Curse, the General escapes his terrible punishment when he and Luke trick Annabeth into enduring it. He sets out to gather monsters for Kronos's Army, and to hunt down the Ophiotaurus, whose burned organs would allow it's slayer to gain the power to destroy Olympus. He is first seen with Luke and a captive Artemis, forcing Artemis to hold up the sky in Annabeth's place.

He is next seen in the Air and Space Museum, where he summons Skeleton Warriors, formed from the teeth of a dragon, along with the aid of ancient rituals, to hunt down Percy Jackson and the others accompanying him.

He is finally encountered in San Francisco, where he faces off against Percy Jackson and Zoe. They attack him to no avail, as he toys with Percy with a javelin and effortlessly deflects Zoe's arrows. Percy then realizes that Artemis is the only one who can defeat him, freeing Artemis and enduring the punishment himself. Artemis duels Atlas with two long hunting knives, luring him towards the sky. Atlas manages to corner her, taunting her by saying, "The first blood in a new war." Zoe moves in to defend Artemis, but is knocked into the rocks, speeding up a poison recently given to her and dies later on. Artemis blocks Atlas' final blow and knocks him back under the sky, taking his freedom once again. He curses and cries at the gang as they fly away on three pegasi.

He is later heard moaning under the weight of the sky in The Battle of the Labyrinth.

In The Last Olympian, Kronos decides not to free him, despite being the best fighter (second only to Kronos himself). This is because he had failed to capture Bessie, and because Artemis escaped.

Physical description
Atlas looked like "a living statue", with dark slicked back hair, eyes like stone, light brown skin, and a muscular build. He is tall, with a brutal face, huge shoulders, and hands that could "snap a flagpole in half".

Personality
Atlas is seen as being quite vain and arrogant. He has a short temper and takes great pride in being Kronos' second in command (as Luke is not a Titan). His rash personality allowed him to be bested by Artemis in combat. His arrogance is displayed several times, such as when he mocks Percy Jackson and later, Artemis. He casts fear into every one of his servants, including Luke and Dr. Thorn.

He is loyal to Kronos' cause and seems to have a lust for blood much like Ares, as when he says to Artemis when he has her cornered, "The first blood in a new war." He also despises the punishment the gods gave him (holding the sky on his shoulders) and writhes with anguish when forced to endure it again. This is probably why he bears a short temper and why he finds delight in killing gods and demigods alike. It's also likely that centuries of enduring this punishment had an affect on his mentality.

Abilities
Atlas is considered by many to be the most powerful of the Titans besides Kronos.

The General's most seen talent is his adept strategic abilities, which were put to great use in the First Olympian War. He laid a plan in The Titan's Curse to use the Ophiotaurus to destroy Olympus, which caused great trouble for Percy and his companions in the book.

Another great ability of his is his prowess in combat. He uses a metal javelin to fight Zoe Nightshade, Percy Jackson, and Artemis. His abilities with it are able to outmatch Percy Jackson and go on par with Artemis, who was described as being extremely agile in battle. He's even able to send Percy flying with just one swing of his javelin.

Perhaps his most extraordinary ability, coming from his Titan heritage, is his ability to lift the entire sky. This was a punishment given to him for serving as Kronos' right hand man during the First Olympian War. He despises this punishment more then anything else, but still, it is a remarkable ability, even for a Titan.

Film
Atlas has not yet been cast, and presumably will not be until the film version of The Titan's Curse starts production.
