This is a list of DC Comics characters that appear in the Flashpoint reality even when its sequel Flashpoint Beyond was released.
Major characters
Flash
Barry Allen is the main character of Flashpoint and is one of the few characters who remembers the original timeline. Despite being from the original timeline, Barry's personal history is different: Barry initially does not have his super-speed or his secret identity as the Flash; his mother is alive and; he has no relationship with Iris West. Despite having memories from the initial timeline, Barry's memories change sporadically throughout the series, causing him to recall the events of the Flashpoint timeline such as Aquaman's flooding of Europe and Wonder Woman's conquest of England. With the aid of Batman, Barry manages to convince various heroes and villains to collaborate in stopping Aquaman and Wonder Woman from escalating their conflict into a world war. However, during the heroes' final assault on the Amazonian kingdom, Barry's efforts are almost proven futile, as Professor Zoom appears in the wake of the battle, taunting him due to his inability to prevent Zoom's manipulations from taking effect. Thawne then reveals to the Flash that the entire Flashpoint timeline is actually the result of Barry's attempt to prevent Zoom from murdering his mother, and that Zoom now has the ability to kill the Flash at his own leisure without negating his own existence. After learning his inadvertent role in the creation of the Flashpoint timeline, Barry tries to set things right by trying to stop his younger self from changing history. However, the cursed immortal Pandora takes advantage of the situations and creates another alternate timeline slightly different from the original, and Barry fails to realize it.
Reverse-Flash
Professor Eobard "Zoom" Thawne, the Reverse-Flash, serves as a red herring of the Flashpoint timeline, and, unlike Barry, the Reverse-Flash still has his powers at their fullest. Eobard constantly toys with Barry by speaking to Barry's mother while running at super-speed and replacing the costume inside the Flash's ring with a Reverse-Flash costume. He is revealed to have caused tragedy in Barry's life after realizing that preventing Barry from becoming the Flash would wipe out his own existence. In the penultimate issue, Reverse-Flash appears before the Flash during the battle between the Amazons and the Atlanteans. He then reveals to Barry that the Flashpoint timeline was actually created by Barry himself, after he traveled back in time to stop Eobard from killing his mother. According to Zoom, these actions transformed him into a living paradox, no longer requiring Barry to exist, and allowing him to kill the Flash without erasing his own existence. Zoom continues to taunt Barry with this knowledge until he is stabbed in the back by an Amazonian sword and killed by Batman. He later returns as an alternate timeline version, before his pre-Flashpoint memories are restored.
