He's back, y'all. Again.

Arnold Schwarzenegger, star of 1984's sci-fi classic "The Terminator," shared a new look on social media Thursday of his iconic T-800 character from the upcoming "Terminator: Dark Fate," which also unveiled stills of a returning Linda Hamilton and debuting co-star Mackenzie Davis.

Plot details for the sixth "Terminator" (in theaters Nov. 1) remain a mystery, though theaters owners and journalists got a first look at footage during Thursday's Paramount presentation at CinemaCon. The "Dark Fate" cast is also being recognized at the CinemaCon Big Screen Achievement Awards in Las Vegas.

The CinemaCon crowd saw a couple of scenes, one involving Davis' mysterious "enhanced human" character Grace showing up from the future naked – a la Schwarzenegger in the first "Terminator" – and being helped by some teens. Another featured Linda Hamilton's iconic heroine Sarah Connor blowing up a couple of Terminators with a bazooka and borrowing her old co-star's legendary line: "I'll be back."

Schwarzenegger also showed up for the panel and was greeted by a cheering audience, according to The Hollywood Reporter.

"This is a fundraiser for my next political race," joked the actor and former California governor, who also pointed out Hamilton's still amazing physical shape. "Now all these years later, she's doing the push-ups and chin-ups again. She's ripped again."

In the new official "Dark Fate" shots, Schwarzenegger's T-800 is a bit grayer but still looks like he can go a few rounds with bad-guy robots. (His cyborg last showed up in 2015's box-office bomb "Terminator Genisys," though the less said about that, the better.)

Hamilton's character looks as intense as ever in the actress' first "Terminator" film since 1991's "Terminator 2: Judgment Day." Davis also looks warrior-esque (though one wonders if she's really a Terminator), but Natalia Reyes has the weathered look of a normal woman who's gotten caught up in a serious sci-fi situation.

Gabriel Luna is giving off the same chilly killer vibes as Robert Patrick's T-1000 in "Judgment Day," so it's probably safe to say he's the latest villainous Terminator. And one might guess Diego Boneta is an ordinary guy who also allies himself with our heroes. Or he might be totally evil – we'll see soon enough.

James Cameron, who wrote and directed the first two "Terminator" films, has handed the reins over to "Deadpool" director Tim Miller for "Dark Fate." Cameron is credited as a producer this time around, and told USA TODAY in 2017 that future films would have Schwarzenegger passing the torch to other Terminators.

"We have to create something new and fresh that stands on its own," Cameron said. "I would like to think that Arnold would be a part of it. But I think it would a mistake to make him as central as he has been."
