Ace West

WallaceDaniel "Ace" West is a superhero appearing in American comic books published by DC Comics. Originally introduced as a biracial interpretation of Wally West as part of DC's The New 52 relaunch, the comic DC Rebirth #1 later established that he is actually a new character of the same name, being Wally's cousin and the son of the Reverse-Flash (Daniel West), both named after their great-grandfather. To avoid confusion, the character was renamed in later comics as Wallace West, and later simply as Ace West. Forming the speedster duo "Speed Force" with his love interest Avery Ho, the two serve as the main characters of the ongoing series Speed Force.

The character was inspired by a desire to feature an African-American iteration of Wally West in the Arrowverse series The Flash following the similarly blackJesse L. Martin's and Candice Patton's respective castings as Joe and Iris West. Ultimately, Keiynan Lonsdale was cast as the character, depicted as West's long-lost brother. Lonsdale reprised the role in Legends of Tomorrow and Supergirl.
