The Flash is a superhero TV show created by DC Comics that involves a main character Barry Allen who is the hero and Harrison Wells, the inventor of the particle accelerator that explodes and creates metahumans, humans with special abilities. Barry Allen's meta-ability is super speed, which he uses to stop other bad metas and hand them into law enforcement. I try really hard not to give any spoilers, but this show has a 5th season coming up. It involves lots of aspects of theoretical physics, such as secret quantum decryption algorithms that only STAR Labs (the group that the Flash works with), pocket dimensions, timeline travels, and more. The Flash's (Barry's) mother Nora was killed by "something impossible" and Barry's father Henry was accused of his murder and he said and did not do it. The Flash does not share his identity and works under that stage name/pseudonym when saving people.
