Wally West is the biological son of Rudy and Marry West. He grew up a normal kid in Central City until his aunt Iris married Barry Allen. Not long afterward Wally discovered that his uncle was non other then the hero of central city, The Flash. Being the Flash's biggest fan, he begged his hero to let him become his sidekick. Barry refused, not wanting the responcibility of grooming a sidekick or putting his nephew in danger. This didn't stop Wally, he found Barry's notes on the experiment that gave him and Jay Garrickson their powers. He replicated the accident in his garage which blew it up, landing him in the hospital. Although this granted Wally the uncanny powers of super speed, Barry felt guilty and reluctantly agreed to let him become Kid Flash, but only if he did exactly as he said.
Wally became Kid Flash that year, being very different from the Flash the two has conflicting personalities which mysteriously merged during the heat of a mission. Soon, Flash introduced him to the League where he met Robin, Batman's sidekick. Over the next few years Wally became very good friends with Robin who revealed his identity as Dick Grayson to him, Wally did the same as the two had become best friends. Soon they also met two other sidekicks, Speedy and Aqualad. Speedy being very distant, the two became close friends with Aqualad and over the years finnaly they developed enough experience to be graduated into being recognized by the League. In this event Robin, Aqualad and Kid Flash assigned their own mission to themselves where they discovered Superboy who helped them to announce themselves as a team to the League, officially forming the Teen Titans.
Wally was far more involved with the Titans, rather then with his Mentor, which was no bother to the Flash. Wally eventually became a full time Titans alongside his new comrads. This lasted for years until Robin left Batman's side, resigning as a superhero, with this the Titans fell apart. Aqualad returned to the seas while Wally decided to retire from heroism. Wally then returned to his normal life until he graduated high school, this is when Dick returned as Nightwing. The two then decided to reform the Titans, causing Wally to retake the mantle of Kid Flash and become the leader of Titans West.
