The original Avengers are bonded together for life. The five original cast-members have matching tattoos to signify everything they've been through together.

Making It Permanent

To mark the release of world-conquering superhero team-up movie Avengers: Infinity War, the long-time friends and colleagues, enlisted NYC tattoo artist Josh Lord to mark their bond in ink.

He was also given a not-as-impressive tattoo of his own, via all five Avengers.

"Five of the original six Avengers got a tattoo. ... 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, ... flew out to LA, he did me, did (Jeremy) Renner, and then we just bullied (Chris) Hemsworth into doing it, and he got it," explained Robert Downey Jr., who plays Iron Man, to EW.

They then turned their attention to Lord himself, who had to suffer under the weight of an Avengers-powered needle.

"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," continued Downey Jr.

It's customary for the cast and crew of a movie to celebrate once a film has wrapped production, but it's typically with a lavish party to mark all of the hard work that's gone into the finished product.

The MCU is no ordinary place. So, it makes sense that the original cast would want to celebrate a decade of being part of it. Matching tattoos might seem extreme, but it's certainly one way of bonding with work colleagues together for life.

Making It Count

Downey Jr., who starred in the first film in the long-running series, 2008's Iron Man, shared a couple of videos of the painful process on Instagram.

He also offered fans a closer look at the tattoo, which is a stylized Avengers logo combined with the number 6, representing the six original heroes from 2012's The Avengers.

Renner, who plays Hawkeye, also posted a photo of himself with Lord on Instagram. The tattoo artist then took to the platform, to share a photo which included an Iron Man Easter egg.

Lord wore a Black Sabbath T-shirt featuring the band's hit song "Iron Man." That particular song played over the end credits of the movie, immediately after Tony Stark's public reveal as the superhero.

Stark also wore a Black Sabbath tee in the 2012 Avengers film, as a tribute to the iconic song.
