It has been six years since the first Avengers movie hit theaters. Although the latest film, Infinity War, has assembled a long list of heroes, at first, there were only six. Thor, Iron-Man, Hawkeye, Black Widow, Hulk, and Captain America assembled to defeat Loki, who seems like child's play compared to Thanos at this point. In honor of being the first crew, five of the six heroes got matching tattoos. Hulk, played by Mark Ruffalo, decided to sit this adventure out. 

Via an exclusive interview with EWRobert Downey Jr. explains the process that went into getting the matching "A" tattoos, stylized after the Avengers signature logo.

"Five of the original six Avengers got a tattoo,” Robert Downey Jr. stated. “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.”

Downey Jr. also posted videos of the tattoo bonding moment as well.
