Josh Brolin's Thanos might be at the very center of Avengers: Infinity War and Avengers 4, but no one can be really sure that Thanos story is going to end with Marvel's two-part Avengers movie.
Though Marvel hasn't explicitly named Thanos' future after Avengers 4, Brolin has seemingly confirmed the possibility of the Mad Titan's end in an interview with Empire Magazine (via the Digital Spy).
"I don't like the idea of a franchise, personally. That's what makes the Thanos thing really great. It's a finite thing, and I like that," the Marvel actor explained the latest issue of the magazine.
Though it's possible that Thanos might make it out of the fight alive after the fourth Avengers installment, it's hard to imagine the Earth's Mightiest Heroes surviving Avengers 4 with Thanos still hanging around. After all, the battle for the universe seems pretty much like a kill-or-be-killed kind of scenario, and it's unlikely that Marvel's going to allow all of its superheroes to die in the culmination of the Marvel Cinematic Universe.
While Thanos' end seems like a pretty inevitable fate, Brolin still has a pretty bright future in the comic book industry. The Marvel actor's still probably going to be pretty busy playing Cable for 20th Century Fox.
Avengers: Infinity War premieres April 27.
