A Twitter account managed by Trump's reelection team posted a super-produced clip in which DT's head is superimposed over Thanos' body from 'Infinity War' ... and he snaps his Democratic enemies -- who just introduced articles of impeachment -- to dust.

They captioned the post, "House Democrats can push their sham impeachment all they want. President Trump's re-election is 𝗶𝗻𝗲𝘃𝗶𝘁𝗮𝗯𝗹𝗲." Funny, right? WRONG ... so says the comic book writer and artist who brought Thanos to life back in 1973. He ain't laughing.

Jim Starlin -- the creator of Thanos -- says he finds it pretty disturbing that Trump's goons are comparing him to a mass murderer -- Thanos literally goes around blowing up planets in "The Avengers." He says, "How sick is that? These are sad and strange times we are going through. Fortunately all things, even national nightmares, eventually come to an end."

Starlin also said he felt violated by the creative hijacking, and said DT has an infantile ego.

Funny enough ... the scene of Thanos snapping that Trump's team used in their hypercut is actually from the part where he dies in the final movie. Spoiler alert ... Tony Stark ends up with all the Infinity Stones, and then snaps Thanos and his henchmen to oblivion.
