Flash (Arrowverse)

After witnessing his mother's murder at the hands of a mysterious figure as a child, Barry Allen was taken under the roof of Joe West, a close friend of the convicted yet innocent Henry Allen. Barry excelled at science and forensics, working for the Central City police department while dedicating his life to finding the "man in yellow" and bringing him to justice.

Barry, fascinated by the engimatic scientist Harrison Wells, attended his unveiling of the particle accelerator. However, Barry was required to return to his lab back at the police department before the accelerator could be activated. A lightning storm took place just as the accelerator ripped open a wormhole, and the lightning struck Barry and splashed him in a variety of dangerous chemicals.

For several months, Barry was stuck in a coma under the care of a now crippled Wells. When Barry awoke, he discovered the particle accelerator had changed his molecules, connecting him to the "Speed Force" and forever changing him. Initially struggling with his abilities, Barry was convinced by his good friend Oliver Queen to use these powers for good. Under the tutelage of Dr. Wells and his two remaining staff members Cisco Roman and Dr. Caitlin Snow, Barry utilized his new abilities for protecting Central City from more metahumans like him as The Flash.
