Legends of Tomorrow unleashed a bevy of news during its Comic-Con @ Home panel on Sunday, including this surprise twist: Matt Ryan will be back as a series regular for Season 7… but as a different character!
“While John Constantine’s arc on the show is coming to an end in Season 6, Matt Ryan’s journey with the Legends is not over,” executive producer Phil Klemmer revealed during the Q&A. Ryan will next take on the role of Dr. Gwyn Davies, an eccentric scientist from the early 20th century who might be the team’s only hope next season.
“As everyone who loves him knows, in the end, John Constantine will walk his path alone,” added Ryan, who first appeared on the Arrowverse spinoff in Season 3. “The time has come for John to part ways with the Legends, and for me to part ways with John. I’m really excited to be creating this new role on the show and having some fun with it — discovering how this new character fits in and causes some trouble for the Legends.” [Source]
