The CW has released stills from next Tuesday's "Invincible" episode of The Flash, and they offer the first official images of former Arrow star Katie Cassidy as Black Canary's Earth-2 counterpart, Black Siren.

After Zoom (guest star Teddy Sears) unleashes an army of Earth-2 meta-humans on Central City, Barry (Grant Gustin) is shaken when he sees their leader is the Black Canary's Earth-2 doppelganger, the Black Siren (guest star Katie Cassidy). Meanwhile, Wally (Keiynan Lonsdale) takes to the streets to help The Flash stop the meta-humans, which worries Joe (Jesse L. Martin). Iris (Candice Patton) and Henry (guest star John Wesley Shipp) are concerned about Barry taking on Zoom.

Check out the photos in our gallery at the bottom of the page.

Jesse Warn directed the episode with story by Greg Berlanti & Andrew Kreisberg and teleplay by Brooke Roberts & David Kob.

"Invincible" episode of The Flash will air Tuesday, May 17 at 8PM on The CW!
