The CW has released an official portrait of The Flash's Tom Cavanagh as the DC character Pariah, for its upcoming Arrowverse crossover "Crisis on Infinite Earths."

The portrait provided to KSiteTV features Cavanagh donning his Pariah costume, and is similar to a previous portrait released for Audrey Marie Anderson's Harbinger two weeks ago.

An unofficial behind-the-scenes photo of Cavanagh in his Pariah costume was captured last week, featuring the actor standing among several longtime Arrowverse heroes, including Superman, Elongated Man, Black Lightning, Flash, Spartan and Iris West-Allen, as well as newcomers the Monitor, Harbinger, Ryan "Atom" Choi and Kingdom Come Superman. The group is gathered on the bridge of the Waverider, the time-traveling ship from DC's Legends of Tomorrow.

"As part of 'Crisis on Infinite Earths' crossover, not only will Tom [Cavanagh] be playing the two characters we heard here, he will also be playing Pariah as part of the crossover," The Flash showrunner Eric Wallace revealed at the show's Comic-Con International panel. "He works for the Anti-Monitor."

"In the original miniseries, it's Pariah who is very much integral in releasing the Anti-Monitor," he continued. "For Tom to play such a pivotal character... it's just going to tear your guts out and make you cry."

In Marv Wolfman and George Pérez's Crisis on Infinite Earths, Pariah inadvertently summoned the Anti-Monitor and thereby launched the events of the comic. Pariah was one of the greatest scientists on his world but, as a result of his experiment to view the creation of the universe, he caught the Anti-Monitor's attention. The Anti-Monitor used Pariah's experiment as a tool to free himself from a prison made by his brother, the Monitor. The Monitor snatched Pariah away from his world just before the Anti-Monitor destroyed it. The destruction of Pariah's world gave the Anti-Monitor enough power to begin his quest to annihilate the multiverse.

"Crisis on Infinite Earths" begins Sunday, Dec. 8 at 8 p.m. ET/PT on Supergirl, then continues in Batwoman on Monday, Dec. 9 at 8 p.m. ET/PT and in The Flash on Tuesday, Dec. 10 at 8 p.m. ET/PT. After the winter hiatus, the crossover will conclude on Tuesday, Jan. 14 in Arrow at 8 p.m. ET/PT and in DC's Legends of Tomorrow at 9 p.m. ET/PT.
