The doctor is in, with Titans reportedly casting Michael Mosley as Doctor Light for season 2. Created by Gardner Fox and Mike Sekowsky, renowned physicist Arthur Light debuted in 1962's Justice League of America #12. With the ability to harness light in a variety of ways, including to render himself invisible, Light has battled the Justice League and the Teen Titans repeatedly across the decades. Despite his name, he has served as both a comedic menace and a more darkly serious threat. He became more prominently the latter in the mid-2000s when it was revealed that the villain was a serial rapist.
Titans was the inaugural series on the DC Universe streaming service, rapidly spawning a Doom Patrol spinoff. Season 1 followed the adventures of Dick Grayson, Kory Anders aka. Starfire, Rachel Roth aka. Raven and Gar Logan aka. Beast Boy, as they joined forces and attempted to unravel the mystery surrounding Rachel. An instant hit - especially on Netflix - the show was quickly renewed. The cast has already been confirmed to be expanding significantly in season 2, with Joshua Orpin signing on as Superboy alongside Drew Van Acker as Garth aka. Aqualad. As well as them, the new season will mark the arrivals of Chella Man as Jericho, Chelsea T. Zhang as Rose Wilson, and their villainous father Slade Wilson, aka. Deathstroke.
According to Deadline, Mosley will join them and play the notorious light-based villain in Titans' sophomore outing. The actor is most recently known for his portrayal of Pastor Mason Young on Netflix's Ozark. He will also continue to reprise the role of Everett Lynch in the 15th and final season of Criminal Minds. It's not yet known in which episode Mosley's Doctor Light will debut, or how big of a role he will play across the season. With Cadmus labs introduced at the end of season 1, however, the show is learning into more scientifically created heroes and villains.
A female version of Doctor Light previously appeared on multiple episodes of The Flash, played by Malese Jow. Her iteration, however, was more directly inspired by Kimiyo Hoshi. Despite sporting the same name, similar costume, and identical powers, Hoshi is infinitely more heroic in nature. With the Arrowverse's version following suit, Mosley's depiction will mark the villain's first live-action appearance. The character was nowhere to be seen in the first Season 2 trailer, however.
It's unclear which version from the comics fans will be able to expect. Given Titans established nature as a far grittier take on the superhero genre, however, it wouldn't be too big of a leap to assume their Doctor Light will lean more towards darker territory than comedic. Across his tenure in the comics, Light has also had ties to Deathstroke, with the latter even spurring on Light's return to villainy in the New 52 run. As such, season 2 could see him aligned with Esai Morales - the fellow Criminal Minds alum confirmed to be playing Slade Wilson. Doctor Light could easily be playing a secondary villain to Deathstroke's Big Bad, similar to The Family and Trigon in season 1. Equally, they could both be part of Doctor Light's own established comic book team, The Fearsome Five, who have faced off with the Titans on numerous occasions. Whatever the case, Mosley will surely bring a level of gravitas to the role. And Doctor Light will no doubt prove a handful for the fledgling superhero team.
Titans season 2 premieres September 6th on DC Universe.
