Katie Cassidy Goes Black Siren in New The Flash “Invincible” Promo Photos

Promo photos from the next new episode of The Flash have been released. The episode is called, “Invincible” and will feature a guest appearance from Arrow’s Katie Cassidy!

In the episode, “After Zoom unleashes an army of Earth-2 meta-humans on Central City, Barry is shaken when he sees their leader is the Black Canary’s Earth-2 doppelganger, the Black Siren. Meanwhile, Wally takes to the streets to help The Flash stop the meta-humans, which worries Joe. Iris and Henry are concerned about Barry taking on Zoom”.

OH MY GOSH!! Katie looks fantastic in these photos! Ugh I am in love with her Black Siren look.
