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.

Still can’t believe that we get to have an essentially 3 hours long movie of DC crisis storyline on TV and I get to be small part of it. Here is a concept I did of fan favourite Leonard Snart played by Wentworth Miller, in his full Citizen Cold glory with visor and parka. Costume design by Maya Mani.

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".

Have you guys watched the Crisis on Earth X yet?! It’s prettty much a 4 hours Justice League movie! So proud of all crews and glad I got to be a part of it! Here are little peaks at the new characters I did concepts for costume designer Maya Mani on the crossover. Also awesome animated designs on the freedom fighter series on @cwseed by @philbourassa ! @cw_arrow @cwtheflash @cw_legendsoftomorrow @supergirlcw @dccomics #theray #overgirl #darkarrow #blitzenflash @stephenamell @cavanaghtom @melissabenoist @russelltovey #concept #illustration #costume #design

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.
