Disney's D23 EXPO 2017Josh Brolin's insane physical transformation for his role as Cable in "Deadpool 2" grabbed lots of attention when the actor -- who pulls double Marvel duty as Thanos in the traditional MCU flicks -- debuted his new bod on social media this summer. Fellow MCU star Dave Bautista, who plays Drax in the "Guardians of the Galaxy" series, was among those impressed by Brolin's physique -- so much so, in fact, that he's pledged to get himself in even better shape by the time the two start working together on the fourth "Avengers" flick this fall.

In an interview with The Hollywood Reporter, Bautista admitted that he didn't even recognize his pal when Brolin approached him at the gym a couple months ago (Brolin alluded to this encounter in his original Instagram post depicting his Cable workout), so significant was the latter actor's metamorphosis.

"He is not only jacked, but he is shredded," Bautista told THR of Brolin. "His face is all sunken in like a model. He is like a completely different person."

Bautista knows a thing or two about getting jacked, thanks to his past as a semi-professional wrestler, but the buff actor said he was pretty intimidated by Brolin's appearance -- and it's given him some serious workout motivation.

"I am known for being in shape and being a big guy, and he actually made me self-conscious!" Bautista told the trade. "I swear to God, I promised him that in November, when I do some work on '[Avengers] 4,' I told him, 'I will be in better shape for that because you make me self-conscious, f*cker!'"

Look for an even-more-jacked Bautista alongside Brolin when "Avengers 4" -- a.k.a. "Infinity War Part II" -- hits theaters in May 2019.
