In addition to the plethora of heroes already slated to be featured on The CW's "Crisis on Infinite Earths" crossover, the event's showrunner has teased the addition of another mystery character.
Architect Marc Guggenheim acknowledged a fan's tweet, which asked if viewers could expect appearances from The Hawks, Vixen, and/or The Ray. In his response, Guggenheim replied, "One of the three."
The Hawks are Kendra Saunders and Scythian Torvil, aka Hawkgirl and Hawkman, who appeared in DC's Legends of Tomorrow. Mari McCabe, aka Vixen, was featured in the animated Arrowverse web series of the same name, and later made a live action appearance on Arrow. Ray Terrill, aka The Ray, appeared as a member of Earth-X's Freedom Fighters in the last season's Arrowverse crossover, "Crisis on Earth-X."
The confirmation is merely the latest tease heralding appearances from additional characters as part of the impending event, both from within and outside the Arrowverse.
"Crisis on Infinite Earths" begins Sunday, Dec. 8 on Supergirl, then continues in Batwoman on Monday, Dec. 9, and then picks up in The Flash on Tuesday, Dec. 10. After a winter hiatus, the crossover concludes on Tuesday, Jan. 14 on both Arrow and DC's Legends of Tomorrow.
