You've seen the Avengers save the universe over and over again. You've seen them take on Loki. You've seen them best Ultron. And as for what you've seen happen in Avengers: Endgame... well... we'll hold off on the spoilers for the sake of the three people left in the world who haven't seen this movie yet.
Now, it's time to see exactly how all your favorite Marvel heroes and heroines look without their special effects makeup and body armor as they walk the Avengers World Premiere red and purple carpets.
Some, such as Robert Downey Jr., look similar on and off the screen. As for Bradley Cooper's Rocket Raccoon... well, not so much.
But no one gets a bigger makeover for the big screen than the Marvel Cinematic Universe's big bad villains. It takes a lot of makeup and special effects to turn Josh Brolin into the mighty Thanos, to turn Cate Blanchett into Hela and to turn Ross Marquand into Red Skull.
And hey, even though Thor: Ragnarok's Grandmaster is so clearly... uhhhhh dadadadadada... Jeff Goldblum, we're pretty sure Jeff doesn't wake up and get out of bed every morning looking like this.
What does Hulk actor Mark Ruffalo look like when he is not all green and angry?
How about Guardians of the Galaxy actress Karen Gillan, who plays Nebula, without all her character’s crazy makeup?
There is no question that Paul Bettany's Vision barely looks anything like the recognizable British actor. Same goes with Zoe Saldana's Gamora. And don’t even get us started on James Spader as Ultron.
"The technology was such that I put on the suit and you do a range of motion," Spader told E! News about how his performance as Ultron was captured. "They record the range of motion with all the markers on and all the transmitters and everything, and then they sort of plug it into some program. I would move and I could watch it live as Ultron. And that's the first time I stood up a little straighter."
But enough about the tech: It's time to compare these off-duty Marvel superheroes and villains with their on-screen personas.
You will be shocked to see how different some of these celebrities look when they ditch the CGI and special effects makeup for their red carpet (and purple carpet) finest.
