The star-studded cast of 'Avengers: Infinity War' is now officially tied together through matching ink. Five of the six superheroes assembled to mark themselves with the iconic Marvel logo.

“Five of the original six Avengers got a tattoo,” Robert Downey Jr. told Entertainment Weekly. “And the sixth was the tattoo artist, who gave it to five of us, the one who opted out being Mark Ruffalo. It was (Scarlett) Johansson’s idea, and she and (Chris) Evans did it in New York. Then, their New York guy, Josh Lord, who is amazing, flew out to LA, he did me, did (Jeremy) Renner, and then we just bullied (Chris) Hemsworth into doing it, and he got it. And each one of us drew a line on the artist with his own tattoo gun and it was a total massacre. Each of us contributed to giving the tattoo artist the sixth tattoo that he designed for us. By the way, he’s got another one on him that Scarlett did, which is beautiful, which is crazy, because the line she drew on him, which was just supposed to be a straight line, looked like a lightning bolt. It was a mess.”

Chris Evans, who plays Captain America, took to Twitter to share a video of the tattoo process.

Having the superhero sign permanently tattooed on the stars' bodies lets audiences know the bond among the actors must be real.
