While a fourth season of DC’s Legends of Tomorrow has yet to be confirmed, Matt Ryan’s John Constantine has already been announced as a series regular. Warner Bros. Television press release didn’t offer too many details, except to say that Constantine would join the main team aboard the Waverider. 

Created by Alan Moore, Steve Bissette and John Totleben, Constantine was first introduced in The Saga of Swamp Thing. The character went on to star in 300 issues of DC’s Hellblazer series. 

Ryan previously portrayed Constantine for a short-lived TV series on NBC between 2014 to 2015. He later reprised his role as the cult classic character on a season four episode of Arrow entitled “Haunted.” While this was a one-time Arrow appearance, Ryan has since made a few appearances during the current season of Legends of Tomorrow.  

Along with appearing in the season finale, and possible fourth season, Ryan will voice Constantine in the upcoming Constantine series. This animated series will debut this March 24, 2018 on The CW Seed. 

DC’s Legends of Tomorrow airs on Monday nights at 8 PM on The CW.
