After first teasing his appearance back in March, Wally West is finally—officially—heading to The Flash. The CW series has tapped Australian actor Keiynan Lonsdale (Insurgent) to play the iconic character from the comic books, who becomes Kid Flash. Lonsdale will make his debut on the show this winter.

"Just like when we met [Flash star Grant Gustin] for the first time, we instantly knew Keiynan embodied all the heart and courage of a hero," executive producer Andrew Kreisberg said in a statement. "We are so excited to be bringing this much-beloved character onto the show."
