Originally, the twentieth episode of Arrow's second season was going to act as a backdoor pilot, and were it popular enough the series would be greenlit. However, after executives from The CW Network saw "The Scientist" and "Three Ghosts", Barry's premiere episodes on Arrow, they made the call to order the series straight to pilot. On May 8, 2014, The Flash was picked up to series. On October 21, 2014, The Flash was green lighted for a full season by the CW, extending from 13 episodes to 23. The Flash was renewed for a second season on January 11, 2015.
Barry Allen was 11 years old when his mother was killed in a bizarre, terrifying incident and his father was falsely convicted of murder. With his life changed forever by the tragedy, Barry was taken in and raised by Detective Joe West, the father of Barry’s best friend, Iris. Now, Barry has become a brilliant, driven, and endearing CSI assistant, whose determination to uncover the truth about his mother’s strange death leads him to follow up on every unexplained urban legend and scientific advancement that comes along. Barry's latest obsession is a cutting edge particle accelerator, created by visionary physicist Harrison Wells and his S.T.A.R. Labs team, who claim that this invention will bring about unimaginable advancements in power and medicine. However, something goes horribly wrong during the public unveiling, and when the devastating explosion causes a freak storm, many lives are lost and Barry is struck by lightning. After nine months in a coma, Barry awakens to find his life has changed once again - the accident has given him the power of super speed, granting him the ability to move through Central City like an unseen guardian angel. Though initially excited by his newfound powers, Barry is shocked to discover he is not the only metahuman" who was created in the wake of the accelerator explosion - and not everyone is using their new powers for good. In the months since the accident, the city has seen a sharp increase in missing people, unexplained deaths and other strange phenomena. Barry now has a renewed purpose - using his gift of speed to protect the innocent, while never giving up on his quest to solve his mother’s murder and clear his father’s name. For now, only a few close friends and associates know that Barry is literally the fastest man alive, but it won’t be long before the world learns what Barry Allen has become. The Flash.
