Wallace West (character)

Wallace West is a fictional character appearing in comic books published by DC Comics. Originally introduced as a new interpretation of Wally West, as part of DC's The New 52 relaunch, the comic "DC Rebirth" #1 later established that he is, in fact, a new character of the same name, being Wally's cousin, both named after their great-grandfather. To avoid confusion, the character was renamed in later comics as Wallace West.
Keiynan Lonsdale was the first actor to portray the character in live-action in the Arrowverse shows "The Flash" and "Legends of Tomorrow". This version is the brother of Iris West-Allen.
Publication history.
The "reintroduction" of this Wally West to DC Comics following its 2011 The New 52 reboot, which removed Wally West from continuity, was first announced in January 2014. Originally conceived of as a biracial reinterpretation of the classic Wally West character. Wallace is stated in his introductory comics and creators as being the son of Iris West's brother Rudy, as in pre-New 52 stories. However, the original interpretation of Wally West, having been the starring character in the Flash for many years, was still missed by DC's fans, and so the company decided to bring the original Wally back into continuity in Geoff Johns' "DC Rebirth" #1 (2016). "Rebirth" retroactively established that Wallace's father was not Rudy, as previously stated; he was the son of Iris's other brother, the then-recently introduced Daniel West, also the latest incarnation of Reverse Flash, who had redeemed and sacrificed himself as a member of the Suicide Squad.
Fictional character biography.
Wallace first appears in "The Flash Annual" #3 (June 2014) in a story set twenty years in the future, when a jaded, older Flash (Barry Allen) reads about Wallace's funeral and vows to change history. Tying in with the ongoing story "", the story "The Flash: Futures End" #1 depicts an encounter between Barry of five years in the future (when Wallace is supposed to die) and the Barry of 20 years in the future, who is out to prevent it. In the course of the story, Wallace ends up learning that Barry is the Flash and absorbs part of the Speed Force — the source of the Flash's abilities — during the battle between Barry and his future counterpart. He becomes a speedster but his hero career is short-lived; he sacrifices himself to fix a wound in the speed force. Due to the effects of time travel, however, this has implications for Wallace earlier in his history. Around the same time, in the present-day narrative of "The Flash", Barry meets Wallace for the first time through Iris. He is struck by lightning and acquires super-speed abilities; an apparition of his future self-explains that, as a consequence of how his future-self had died repairing the Speed Force, all the power within him was able to travel back in time and use Wallace's lightning accident as a catalyst. Wallace's first act as a speedster is to use his powers to protect a classmate from a bully, using the same artistic elements as Professor Zoom's powers.
"DC Rebirth" #1, part of a company-wide event of the same name, marked DC's attempts to restore much of what it lost in the New 52 reboot, both in tone and in the stories of its characters. It features Wally West watching his younger cousin, Wallace, from outside of time, proud and amazed that he too has become a speedster, and reflecting on how they are both named for the same grandfather. Wally is brought back to reality by Barry, who remembers him for the first time since the events of "Flashpoint". "Teen Titans Rebirth" #1, shows Wallace joining the Teen Titans superhero team as Kid Flash. 
Wallace, as Kid Flash, meets Wally West, as the Flash, when assisting Barry in dealing with a bridge accident, although Wally doesn't explicitly introduce himself to his cousin, simply identifying himself as an ally of Barry, although Wallace accepts him after they work together to save Barry from a temporary infusion of Speed Force energy.
He later discovers that he has been created after Barry created Flashpoint timeline.
Alternate versions.
"Futures End".
In "The Flash: Futures End" #1, the Flash from 20 years in the future is able to prevent Wallace's death by killing Daniel West. After the Future Flash cripples his younger self in their fight and disappears into the past, Barry finds that Wallace has been imbued with the Speed Force. He makes Wallace promise to stop his future self and Wallace dons a silver and red Flash suit, becoming the new Flash, and trains for years to travel back and stop the Future Flash.
In "Flash" #35, Wallace arrives to see the Future Flash fight the present Flash. Wallace is badly injured when he shields the younger Flash from high-speed rocks that the Future Flash flung. Wallace absorbs the excess Speed Force energy that is tearing apart the present Flash and tells him to not give up and that he only learned to be a hero because of him. Wallace dies and releases a blast of Speed Force energy that closes the rupture but unintentionally traps the present Flash in the Speed Force.
In other media.
Television.
A version of Wally West was introduced in "The Flash", portrayed by Keiynan Lonsdale, around the same time that DC reintroduced Wally West in the New 52 – the character that would later be redesignated Wallace West. In "The Flash" season three, Wally becomes Kid Flash when he gains identical powers to Barry from an accident. In this version, he is Iris West's younger brother instead of nephew. In season four, he leaves the team to forge his own identity and eventually joins the Legends of fellow Arrowverse series "Legends of Tomorrow" as a series regular in season three.
