“The Flash” has cast Australian actor Keiynan Lonsdale as Wally West, the iconic speedster from the DC Comics universe who made his debut as Kid Flash. He’ll appear as a series regular in season two.

In comics canon, Wally is the nephew of Iris West (played in The CW series by Candice Patton) — the love interest and eventual wife of Barry Allen (Grant Gustin). While Wally initially served as his uncle’s sidekick and a founding member of the Teen Titans, he later inherited Barry’s mantle as The Flash.

Since Iris doesn’t seem to have any siblings on the show (that we know of), it’s possible that Wally’s origin story will be tweaked for his live-action “Flash” debut. His connection to the West family has yet to be confirmed.
