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.Afterwards he was raised by his uncle and eventually inherited the family fortune and business. Queen grew into a rich thrill-seeking drunken playboy with no real sense of responsibility or direction in his life. Everything changed when he fell off his boat in the middle of the ocean and washed ashore on the remote isolated Starfish Island, clutching a bow – a memento from a Robin Hood movie – which he had used to keep himself afloat, where he was completely stranded. During this time spent without food or shelter Queen developed his skills as a hunter to survive and gained mastery over his bow. Having previously taken everything in his life for granted, this experience taught him self-reliance and made him into a man. His second test of new character was the discovery of drug smugglers on the island run by the ruthless international crime lord China White. Using his new skills, he attacked and destroyed their heroin operation, then delivered them to the authorities before returning home. Realizing 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.

Death

The NSA was under new management and they offered Oliver a job as an agent. They needed him to go undercover and infiltrate the Eden Corps, an extremist eco-terrorist organization. On his first mission with them he was forced to fight his closest friends and allies; gaining their confidence he also started a romantic relationship with their leader Hyrax. He fought off Connor, Eddie Fyers, Arsenal and even the Force of July. Hyrax had a bomb named the Mutajek 9-9 and planned to destroy Metropolis with it. On the plane ride there was a massive firefight with another deep-cover agent, and most of the terrorists were killed. Green Arrow's arm was inside the detonation chamber for the bomb, which would activate if he released his hand. Superman tried to help but had no way of saving him other than tearing off his arm. Rather than allow himself to be crippled Queen let the plane explode, sacrificing himself to save thousands of people. Having been completely vaporized in the blast, there was no body. A small funeral gathering of his closest friends was held in Warriors. There was nothing to bury, so his son fired an arrow into the air and marked its landing as his final resting place, as in the legend of Robin Hood. Connor Hawke then decided to continue on his legacy.

Resurrection

This wasn't Oliver's end, however, as Hal Jordan (during his time as Parallax) returned to save the earth during the Final Night and used his godlike powers to bring his old friend back from the dead. Unfortunately, the reanimated hero was an empty vessel with no soul, whose memories were replicated from his earlier days when he had a stronger liberal conscience. Ollie's more experienced soul remained in a Heaven-like place for a time, until it was reunited with his body in order to defeat an evil warlock named Stanley Dover. Now, the original Green Arrow was back in action with a rare second chance at life to make up for previous mistakes with his loved ones, all while renewing his vows to be a defender of the downtrodden.
With the death of Stanley Dover, Ollie inherited Dover's estate. He renovated it, and established it as the Star City Youth Center. During this time, Ollie rescued fifteen-year-old Mia Dearden from a life of drugs and prostitution. He took her into his confidence, and into his home. Mia developed a crush on Oliver, and began emulating his actions. She even began training with a bow and arrow. Eventually, her extensive training paid off, and she became the new Speedy.

Powers

Oliver Queen's powers, if any, remain unknown. It has been rumored that Green Arrow may in fact be a metahuman. The Department of Extranormal Operations has a classified dossier on Queen, wherein they indicate such a possibility, but as of yet, this information has not been confirmed nor denied.

 Aviation: He used to own and fly his own airplane called the Arrowplane. He still has some skill in flying different types of planes. 

Cooking: Green Arrow's Chili is one of the hottest foods on the planet.  

Master Archer: Oliver Queen is perhaps the finest archer ever known. He claims to be able to shoot 29 arrows per minute (he stated this himself, in the Sound of Violence story arc, when he corrected Black Canary for saying 26). He has a wide-variety of trick arrows, ranging from bola arrows to time-bomb arrows to his infamous boxing-glove arrow. In recent years he has used these arrows sparingly, preferring the time-tested simple arrow. Green Arrow has shown the ability to shoot an arrow down the barrel of a gun, pierce a drop of water as it leaves a tap, and shoot almost any part of the human body; although he aims only to wound and not kill when he shoots. He once shot two arrows down two different gun barrels while upside down, in mid-flip while somersaulting off a building.   

Master Martial Artist: He is proficient in several forms of hand-to-hand combat including Judo, Kickboxing and Karate. Proclaimed as a martial arts master, he has shown the ability to take on seven people at once. He spent several months dedicated to making himself a better fighter and trained with many of the world's finest martial arts teachers and even went through training from Natas, the same person who trained Deathstroke

Master Swordsman: Ollie is also very proficient with a sword, though it is not his preferred weapon of choice. He has beaten Jason Todd in a sword-fight and has deflected an incoming arrow with the sword he carries. 

Acrobatics: He has displayed on many occasions that he is an expert in acrobatics, and often uses this skill while evading enemy fire. 

Politics: Ollie ran for office and became the mayor of Star City for a significant amount of time. He has since resigned from being the mayor and has continued to lean on political issues from time to time.
