New "Crisis On Earth-X" Concept Art Shows Citizen Cold, The Ray, and More

"Crisis on Earth-X" wowed Arrowverse fans when it aired earlier this week, and now fans can get a new look at some of the characters introduced.

Andy Poon, who designs concept art for The CW's DC Comics-inspired shows, recently shared two new pieces of "Crisis" concept art on his Instagram account. The first shows Leonard "Leo" Snart/Citizen Cold (Wentworth Miller), the Earth-X doppleganger that fans were introduced to in the crossover's third hour.

From his more structured ensemble to his comic-accurate glasses, Citizen Cold's costume delighted plenty of DC Comics fans. And with Leo set to reappear in upcoming episodes of Legends of Tomorrow, there's a good chance that fans will get another chance to see it again.

The second piece of concept art shows some of the new masks that made their way into "Crisis on Earth-X".

Fans can get a look at the live-action design for Ray Terrill/The Ray (Russell Tovey), who is set to return in Freedom Fighters: The Ray. The concept art also shows the masks worn by Earth-Xers Kara Zor-El/Overgirl (Melissa Benoist) and Oliver Queen/Dark Arrow (Stephen Amell), as well as Arrowverse mainstay Eobard Thawne/Reverse Flash (Tom Cavanagh).

These pieces of concept art are just one indication of how massive of an undertaking "Crisis on Earth-X" was. But judging by the response surrounding it, that level of work was more than worth it.

Supergirl airs Mondays at 8/7c on The CW. The Flash and Legends of Tomorrow air Tuesdays on The CW. Arrow airs Thursdays at 9/8c on The CW.
