Fan Casting Impulse in Earth-27 fancast (rewrite)

Wally West is the junior partner and nephew-by-marriage of Barry Allen a.k.a The Flash. When Cisco Ramon mentioned he had set up equipment to test that theory inside the particle accelerator, in a huge Contrived Coincidence, lightning suddenly struck the particle accelerator and Wally was bathed in them, giving him the same powers as the Flash. The Flash then taught Wally everything he knew about Super Speed and gave him the identity of Kid Flash. He is hotheaded and impatient, but quick witted and clever. Wally would later become Impulse after he passed his Kid Flash mantle to his cousin Bart Allen.
