Martian Manhunter (J'onn Jonzz)

Centuries ago on the planet Ma'aleca'andra, the Green Martians known as M'yrnn and Sha'sheen gave birth to twin sons. The bearing of twins was uncommon among the Martian culture, and as such, the first of the twins was named J'onn J'onzz, whose name means "Light to the Light." J'onn's brother however, was born a mutant, bereft of a Martian's innate ability to communicate telepathically. He was named Ma'alefa'ak, whose named means "Darkness in the Heart."

As an adult, J'onn became a Manhunter (police officer) and married a Martian woman named M'yri'ah. The two established a modest home for themselves beneath the windswept Martian plains and gave birth to a daughter named K'hym.

Years passed, and J'onn's brother Ma'alefa'ak grew to despise everything about Martian culture. In an ambitious endeavor to commit full-scale genocide against his own people, he engineered a contagious virus known as H'ronmeer's Curse. The virus reacted to telepathic energy, and carried from one Martian to the next whenever they elected to use their psionic powers. The plague responded to a Martian's innate fear of fire, causing them psychosomatic stress so intense, that their bodies and minds would literally burst into flame. J'onn desperately tried to keep his wife and daughter from using their mental gifts, but they were unable and so, contracted the plague. K'hym was the first to experience the symptoms, and M'yri'ah followed soon after. J'onn was anguished as he watched his family burning to death before his very eyes. The trauma of the event shattered his psyche, and nearly drove him mad.

GREEN ARROW

Green Arrow is a vigilante superhero who fights crime using archery, martial arts and technology. In his secret identity he is Oliver Queen, living in Star City as a wealthy playboy and billionaire industrialist turned outspoken liberal politician. He is the leader of Team Arrow; he has also been a member of the Justice League and the Outsiders. As a young child Oliver idolized his hero Robin Hood and was said to be a natural archer, frequently practising with his bow and arrows. He was mildly traumatized the first time he accidentally killed an animal, but when his mother and father were mauled by lions in a tragic safari accident his hesitation to shoot cost them their lives. ealizing that he had found his destiny, he chose to use his abilities and resources as a crime-fighter.With a nickname coined by the press, he made it his mission to protect Star City. He took his cue from Batman and built his own "Arrow Cave," complete with an "Arrow Car" and allegedly a yellow submarine. He and Speedy fought with trick arrows that were designed to be non-lethal.
Green Arrow began developing a personal crisis about which of his identities was more important and doing more good, the crime-fighter or the politician.
Oliver Queen has a very dynamic personality. His passion and intensity make him strong, although he has always had difficulty finding direction in life. Born into wealth, he didn't need to work for most of what he had and was raised with very little responsibility. His experience on Starfish Island taught him self-reliance and showed him there was more to existence, giving him an outlet. In the beginning of his career he has been portrayed as a thrill-seeker, fighting crime not for moral reasons but the sense of adventure. It wasn't until he lost his fortune that he developed his strong social conscience, and outspoken left-wing political viewpoints. This character development has made him much less egotistical in the way he deals with problems.
His attitude towards women has been shown to vary over the years, although he is consistently more attracted to dangerous types. Oliver was originally shown to be a very faithful and enduring partner to his long-time love interest Black Canary, although he has committed infidelity, and retcons to his personality have made him more womanizing.

GREEN LANTERN

Hal Jordan is the most well-known Green Lantern. He was the first earthman ever inducted into the Green Lantern Corps, and has been heralded as possibly the greatest Green Lantern of all time. Green Lantern is also a founding member of the Justice League of America. Hal has also been known as Parallax and the Spectre. Hal Jordan was born in Coast City on February 20th, to parents Martin Jordan and Jessica Jordan, the middle of three children with older brother Jack and a younger brother Jim. As a young child, he idolized his father, a test pilot who worked for Ferris Aircraft. At a very young age, he had to face his greatest fears when his father died in a plane crash right before his eyes. Despite his family's wishes, he followed in his father's footsteps and eventually joined the United States Air Force on his 18th birthday – turning up that very morning outside the Armed Forces Career Center before it had even opened. Many years later, a dying alien named Abin Sur, member of the Green Lantern Corps, crash-landed his ship in the Californian desert. Having selected a replacement officer for his position, the power ring chose Hal Jordan for his ability to overcome great fear. The ring and its abilities were explained to him, and he inherited the mantle of Green Lantern.
As Green Lantern, Hal Jordan patrolled the galaxy and took on many missions in space. Green Lantern was one of the founding members of the Justice League of America, along with the Flash, Aquaman, Martian Manhunter and of course, Superman, Batman, and Wonder Woman. This group first banded together when they met to fight Appellaxians invading the planet, and realized that they worked much stronger as a team than any of them could have individually.

Hal is a righteous hero with a strong willpower and an ability to overcome great fear. Those traits are what make him worthy of becoming a Green Lantern. Having a strong sense of right and wrong, Hal is guided by his own conscience rather than the general rules that most of the Green Lanterns follow. One of his most notable traits is his refusal to admit defeat even in the darkest of situations, which has allowed him to achieve victory even in the most difficult odds.

Despite his virtues, Hal is also reckless and arrogant. More than once he has left his emotions cloud his better judgment, something the Guardians berate him for. Also, Hal is especially hard on himself for allowing Parallax take control of him, which resulted in the destruction of the Green Lantern Corps. But as time passes, Hal is able to overcome his guilt and move on with his life. As a normal human being, Hal does not possess any permanent superpowers. However, when he wields his Green Lantern Ring, Hal is able to fly, shoot laser beams and create constructs from the Green Light of Willpower. Hal posseses no superhuman powers, but with his Green Lantern Ring , he can do many things that a normal human cannot like fly, create solid light constructs, forcefields, and anything the ring and his imagination will allow him to do.

WONDER WOMAN

Diana is the daughter of Queen Hippolyta, the first child born on Paradise Island in the three thousand year history that the immortal Amazons lived there. The Amazons had been created around 1200 B.C. when the Greek goddesses drew forth the souls of all women who had been murdered by men. One soul was left behind, the one that would be born as Diana.
In the late 20th Century, Hippolyta was instructed to mold some clay from the shores of Paradise Island into the form of a baby girl. Six members of the Greek Pantheon then bonded the soul to the clay, giving it life. Each of the six also granted Diana a gift: Demeter, great strength; Athena, wisdom and courage; Artemis, a hunter's heart and a communion with animals; Aphrodite, beauty and a loving heart; Hestia, sisterhood with fire; Hermes, speed and the power of flight. Diana grew up surrounded by a legion of sisters and mothers. When she was a young woman, the gods decreed that the Amazons must send an emissary into Man's World. Wonder Woman did not keep her identity a secret, and she was not at first a "super-heroine". Indeed, her character was in many ways that of a babe in the woods, innocent and without guile. Before embarking on her mission, Diana was given the Lasso of Truth, forged by Hephaestus himself. She was also given the Sandals of Mercury, which allowed her to instantly traverse great distances in seconds. Diana's mission was one of peace, but part of it initially involved defeating a mad plot by Ares to destroy the world.
Wonder Woman had been becoming a popular female hero figure around the time of the Teen Titan's creation. And also, around this time, Wonder Woman had become part of the Justice League of America. Wonder Girl, then Donna Troy, was Diana's pupil and she had join the Teen Titans. Diana, with Batman, Flash, and Aquaman supported the teens to team-up.
Diana has the ability of a superhuman strength, durability, flight, Superhuman speed, reflexes, agility and stamina.
Diana is extremely resistant to blunt force attacks and has a vast tolerance for pain. Pressures, the vacuum of space, extreme heat and cold don't seem to faze her. And she can heal at a meta-human rate. However, Wonder Woman is somewhat vulnerable to piercing weapons, such as projectiles. Rifle or top notch machine-gun fire can cause bruising to slight penetration wounds, WHEN NOT blocked by her bracelets. Knives and swords of magical nature, as well as the attacker, will only cause pain and maybe, a temporary cut.

BATMAN

Batman is the superhero protector of Gotham City, a man dressed like a bat who fights against evil and strikes terror into the hearts of criminals everywhere. In his secret identity he is Bruce Wayne, billionaire industrialist and notorious playboy. Although he has no superhuman powers, he is one of the world's smartest men and greatest fighters. His physical prowess and technical ingenuity make him an incredibly dangerous opponent. He is also a founding member of the Justice League and the Outsiders.
Bruce Wayne swore an oath to rid the city of the evil that had taken his parents' lives. He spent his youth traveling the world, training himself to intellectual and physical perfection and learning a variety of crime-fighting skills, including chemistry, criminology, forensics, martial arts, gymnastics, disguise, and escape artistry.
Batman's presence in Gotham City generated a new breed of criminals, no longer the simple thugs and gangsters involved in Gotham Organized Crime, but more dynamic personalities.
Batman, in most of his incarnations, is a dark and grim hero with a personal vendetta against criminals.
Traumatized by the death of his parents, Batman has sworn to rid Gotham from the criminal elements that took his parents from him. He is very paranoid and obsessive, which often makes it difficult for him to trust other people that aren't Alfred, the Robins, or the Batgirls.

Despite this, Batman has proved to have a great love for humanity, which was instilled by his parents. His father was a doctor, while his mother was a crusader against child abuse. Indeed, Batman's oath of vengeance is tempered with the greater ideal of justice. He refrains from killing, as he feels this would not make him any better than the criminals he fights. He is also a very prominent member of the Justice League and the founder of the Outsiders.

To protect his secret identity, Batman has constructed a fake persona he can use in his civilian identity. To the world at large, Bruce Wayne is a self-absorbed, irresponsible playboy and philanthropist. Only his closest allies know that this attitude is just an act.

The Bruce Wayne/playboy aspect of his character is a facade, while the masked and particularly dark, grim vigilante is marked as the "true" man.
