PERCY JACKSON
Percy Jackson
Percy Jackson is the main antagonist in the Percy Jackson and the Olympians series and one of the main charterers in the Hero's of Olympus series. With his windswept black hair, sea-green eyes, and rakish smile, Percy Jackson is handsome in a tousled, easygoing way. Years of training at Camp Half-Blood have turned the scrawny twelve-year-old newbie into a lean and lithe seventeen-year-old leader of demigods. While his rebellious, impulsive streak has landed him in countless sticky situations, he can usually talk his way out of them thanks to his girlfriend Annebeth, And when that doesn't work, he lets his trusty sword Riptide do the talking for him. His nickname is seaweed brain which was given to him from his girlfriend Annabeth. He enjoys swimming, long walks on the beach, anything to do with water, really. He has a preference for blue food. Percy's dad is Poseidon, which gives him the power to contrail water. He also has this amazing horse named Black Jack. Percy's life has been crazy and full risk, he has saved the world two times and has even been turned into a hamster.

Annabeth Chase
When she's not studying architecture, she's planning battle strategy. Sometimes can't be seen in a New York Yankees baseball cap (because it makes her invisible). Although after the events of Heroes of Olympus her Yankees cap doesn't work she still keeps it around. She appeaser in Percy Jackson and the Olympians and Heroes of Olympus. Dubbed Wise Girl by her boyfriend Percy Jackson. Annabeth Chase, daughter of Athena, is blond, pretty, athletic, and crazy smart. Her stormy gray eyes seem to penetrate and analyze whatever they see, be it a person, a problem, or a place. A natural-born strategist, she prefers to think things through rather than jump right in. Unfortunately, the quests she's been on and the people she's with-hello, Percy?-rarely allow her that luxury. But she's just as good at thinking on her feet and devising plans on the fly.In addition to her intelligence, she is loyal, brave, and confident. Perhaps too confident at times. Her fatal flaw is hubris, or pride in her own abilities and belief that she is more capable than anyone else. This flaw has landed her in serious trouble a few times-and in Tartarus once.But at other times, her confidence helps her achieve greatness. It's pushed her to survive against all odds, help save the world from annihilation (twice-or is it three times?), and pursue her dream of becoming a world-class architect.

Leo Valdez
Leo Valdez is a 15-year-old demigod son of Hephaestus and the one of seven protagonists of The Heroes of Olympus. Leo is described as looking like a "Latino Santa's elf" with curly black hair, brown eyes, a cheerful face, a slim build, and a mischievous smile he likes to tell jokes to hide his sadness after his mother died in a fire in a machanic shop. He is Hispanic-American and a native of Texas. has curly black hair, pointy ears, and an impish grin that screams troublemaker. Leo seems to be constantly in motion-jittering his legs, drumming his long fingers, and poking around the pockets of his magical toolbelt for just the right part for his next project. His mouth is rarely still either, and while some might find his wisecracking patter irritating, those who know him best understand that it's his way of handling tense situations.Leo is currently the head counselor of Hephaestus cabin.

Piper Mclean
Piper McLean is one of the main characters in The Heroes of Olympus. Piper is the Greek demigod daughter of Aphrodite and Tristan McLean and is currently the head counselor of the Aphrodite Cabin. She is currently dating Jason Grace, son of Jupiter. Piper's weapon of choice is Katroptis often used as a magic mirror. Katroptis can show bits of the future. Piper has a special power called Charmspeak. When Piper uses Charmspeak she can get people to do what she wants. Unlike other children of Aphrodite, goddess of love and beauty, Piper McLean prefers to keep a low profile. She downplays her dark-haired beauty, dresses for comfort rather than high fashion, and keeps her relationship to movie star Tristan McLean a secret. But she's no shrinking violet. When she or someone she loves is threatened or in need, she'll use every weapon in her arsenal to help: the persuasive power of charmspeak; a dagger that once belonged to another beauty, Helen of Troy; even a horn of plenty taken from a murderous river god. A true hero, she understands that it's what's on the inside that really counts.

Jason Grace
Jason Grace is one of main protagonist of the Heroes of Olympus. He is the son of Jupiter and Beryl Grace and the younger brother of Thalia Grace. He was a praetor at Camp Jupiter until he gave his rank to Frank Zhang; he is the current counselor of Cabin One at Camp Half-Blood
With his blond hair, sky-blue eyes, and tall, muscular physique, Jason Grace, son of Jupiter-the Roman aspect of the Greek god Zeus-is classically handsome. A small scar on his upper lip, made when he tried to taste a stapler as a youngster, saves him from unapproachable perfection. The inside of his right forearm bears the tattoo of an eagle with the letters SPQR and twelve slashes, one for each year he was at Camp Jupiter. His hair was once cut short but grew out during his time at Camp Half-Blood; it now has a groove cut through it, courtesy of a Celestial bronze bullet shot from the demigod Sciron's gun. Jason wears Imperial gold-rimmed glasses to correct nearsightedness. IVLIVS, an Imperial gold coin that turned into a sword or spear-heads for the sword, tails for the spear-was replaced by a Roman gladius after it was destroyed in a fight with the giant Enceladus.
Jason has a good sense of humor, though that side of his personality is often overshadowed by his serious, sometimes sad demeanor. His friends know him to be kind, gentle, and trustworthy-and his enemies soon learn that he will stop at nothing if his friends are in danger. He has superhuman strength and agility, lightning-quick reflexes, and impressive sword, spear, and hand-to-hand-combat skills. As the son of the god of sky and weather, he can generate storms, fly by summoning the power of wind, and control lightning. But while Jason appears to be all-powerful and mentally strong, he is not impervious to injury and internal turmoil. He struggles to choose which camp to align with, Camp Half-Blood or Camp Jupiter. When the ghost of his enemy Michael Varus stabs him, the wound festers until he finds a way to unite the camps by accepting the title of Pontifex Maximus, high priest of Camp Jupiter, but deciding to live at Camp Half-Blood..
