Professor Zoom
Barry Allen appears as the main protagonist in "", with Justin Chambers voicing the character. Barry is interrupted while visiting his mother's grave on her birthday and leaves as the Flash to battle the Top, Mirror Master, Heat Wave, Captain Cold, and Captain Boomerang at the Flash Museum. Professor Zoom later reveals this to have been a trap for the Flash. He intends to kill Flash along with thousands of others, and link Flash's name to the destruction. The Justice League shows up and defuses all the bombs that Zoom set and all the villains are arrested. Shaken by what transpired, and full of thoughts about his dead mother, Flash parts from his Justice League colleagues and chooses to be alone. The next day, Flash wakes up in a universe where history has happened differently. Here, he has none of his powers, his mother is alive, Iris is married to someone else, and a feud between Aquaman and Wonder Woman has triggered an all-out global war. Flash blames Professor Zoom for messing with the timeline. He enlists the help of Batman (Thomas Wayne, Bruce's father) to regain his speed. He does so by recreating the accident that gave him his powers. The first attempt fails, leaving Barry with third degree burns. The second attempt, however, is successful, with him fully regaining his speed. Barry then gathers up a band of heroes including Cyborg (a government agent), and the Shazam Kids (all of whom become one Captain Thunder when they all say the wizard Shazam's name together) to stop the war and restore the timeline. However, during a fight with Professor Zoom, Flash discovers that Zoom did not do anything, and that it was he who altered time by going back and saving his mother. After Batman kills the evil speedster, Flash travels back and prevents himself from saving his mother, but once again fractures time, creating another alternate timeline which differs in subtler ways from the original. Barry is also in a better place with his mom's death, and is reunited with Iris. He also gives Batman (Bruce Wayne) a letter that Thomas asked him to deliver to his son.
