Genre actor Lance Henriksen has been cast as Obsidian in Season 2 of “Legends of Tomorrow.”

According to TVLine, the 76-year-old actor — best known for his role as Bishop in the wildly successful “Alien” franchise — is set to make his first appearance in episode 5 of the show’s upcoming season.

Henriksen will be introduced as part of Justice Society of America (JSA), whose members also include Rex Tyler/Hourman (Patrick J. Adams), Henry Heywood, Sr./Commander Steel (Matthew MacCaull), Amaya Jiwe/Vixen (Maisie Richardson-Sellers) and Dr. Mid-Nite, who has yet to be cast.

Although not confirmed, John Wesley Shipp suggested in an interview with Variety last May that his new “The Flash” character — Jay Garrick — is also part of JSA.

"The fact that I'm now getting to morph into an entirely different character that is so important to the Justice Society of America, which also bleeds into 'Legends of Tomorrow' — he's such an important character to this whole world — it just opens up enormous possibilities for me as an actor going forward," Shipp said at the time.

As comic book fans know, Obsidian is the son of the original Green Lantern, Alan Scott. He has the ability to fuse with his own shadow, allowing him to fly and pass through solid objects, and possess other people’s shadows. Created by Roy Thomas and Jerry Ordway, Obsidian first appeared in 1983’s “All-Star Squadron” #25.

Obsidian is typically one of the younger members of JSA, so Comicbook.com noted that the show’s decision to cast an older actor for the role could indicate that the Legends will only be meeting him either in the present-day or in the future, as executive producers have already confirmed that the series’ JSA will be a World War II era team of heroes.

Besides starring in the “Alien” film series, Henriksen’s other notable acting credits include “The Terminator,” “Millennium” and “Near Dark,” among many others.

"Legends of Tomorrow" Season 2 will premiere on Thursday, Oct. 13, at 8 p.m. on The CW.
