Diego Luna doesn’t blend into the background. The Real Salt Lake and USMNT midfielder plays with the loose, fearless energy fans associate with his “Moon Boy” nickname, and his tattoos have a similar feel: bold, a little chaotic, and full of personal references to family, faith and football.
Luna has said he wanted lots of tattoos from a young age. He’s also explained a few of the stories behind them. Here’s what can be seen clearly in photographs and what Luna has said about the designs.
Diego Luna’s “Strength” tattoo sits above his ear
“Strength” is one of the easiest tattoos to spot. The word sits in script along the hairline above Luna’s ear. It’s not large, but it shows when he turns his head. The lettering feels personal without looking polished or flashy.
The placement lets it disappear in a straight-on photo, then stand out in profile. In the image above, you can read the script and start to see the other linework around his neck. “Strength” can mean getting through pressure, staying level or remembering what he has already managed.
It sits beside darker neck pieces, as part of a patchwork that seems to have grown over time rather than being planned as one sleeve. That suits a young player still building his career.
The forearm cross and number 15 connect ink with family
Luna’s forearms are among the clearest parts of his collection in match photos. One design has a cross with lettering and Roman numerals; other words run along his forearm. He has also discussed a small boy kicking a ball in a number 15 shirt, tied to his family’s favorite number. That’s a more personal football tattoo than a club logo.
The cross is easy to pick out, while the words and numbers around it make the arm feel like a page of notes. The tattoos move into view when Luna gestures, points or celebrates.
Family is part of how Luna has described soccer. His father played professionally and later coached, and Luna’s path has been closely tied to the people around him. The little footballer reads like a snapshot of where he came from and where he hoped to go.
His neck tattoos make the biggest first impression
The tattoos under Luna’s jaw and across his neck are often what people remember first. They include dark shapes, script and small symbols packed close together. Some photographs show the word “HATE”; other angles reveal linework that disappears under a collar.
Because the neck is so visible, his tattoos look different depending on his shirt and the camera angle. In this image, they peek above the RSL neckline; with a lower collar or a turn of the head, they can take over more of the picture.
The placement looks intense, but Luna has talked about mental health, pressure and learning not to carry every stressful moment onto the pitch. Tattoos can hold moods, jokes and memories as well as anger. His neck ink sits beside softer references to family and faith, so the collection doesn’t follow one neat theme.
His sleeve work turns the arms into a moving collage
Luna’s sleeves are still developing, but black-and-grey linework, script, figures and shaded designs already run from his upper arms toward his wrists. Match kits and camera angles hide different areas, so some photos make the sleeves look denser than others.
The designs change shape as he moves. A tattoo may look compressed when his arm is down and open up when he raises it to celebrate. Match photos show how the pieces look in motion, rather than in a carefully posed studio shot.
The surrounding blackwork gives smaller pieces somewhere to sit. Script, shaded figures and small symbols share the arm, with some open skin between them. The sleeves don’t rely on one large image; their character comes from many smaller choices.
The chest and shoulder tattoos add heavier blackwork
Training and international photos show more of Luna’s shoulders and upper chest. The designs look darker and busier than they do under a clean yellow RSL shirt. Linework reaches toward the collar, with heavier pieces across the upper arm.
The tattoos follow the shape of his body, wrapping around his shoulder and connecting with the sleeve. A high collar can hide the centre of his neck; a short-sleeved top exposes the arm. A celebration pose may show part of his chest that a standard portrait misses.
From a distance, the blackwork gives him a tough silhouette. Up close, some smaller designs point to family and faith, while others remind him how he wants to handle pressure.
The Joker’s “Why so serious?” tattoo keeps the mood loose
One of Luna’s most memorable tattoos is on his leg: a Joker-inspired design with the words “Why so serious?” He has said it’s more than a reference to a character. It reminds him to loosen up when football starts feeling heavy. Luna has said he doesn’t play his best when he gets too serious, angry or stuck in frustration.
The design itself isn’t always visible in match photos, but the explanation is clear. Some of his tattoos mark family or faith; this one is there to shift his mindset.
Professional football brings pressure, travel, selection debates and people judging every touch. The phrase helps him step back. It doesn’t mean he doesn’t care; getting too caught up in the pressure can make him play worse.
The comic-book line fits beside family numbers, script, crosses and dark neck work. It’s personal, but playful too.
What Diego Luna’s tattoos say about his style
Luna’s tattoos are easy to see because they sit on his neck, hairline, forearms, hands and legs. The stories vary: some point to family, some to faith, and others are reminders to keep perspective. The Joker tattoo keeps the collection from feeling too solemn.
Not every design needs a public explanation, or has to match the one beside it. Luna’s tattoos look like choices made at different times, in different moods. A few of the stories may belong only to him and his family.
His style is still changing, and the collection doesn’t look finished. The tattoos give him a strong visual identity, but fans can follow it as it develops alongside his football at RSL and with the USMNT.
The useful thing to take from Luna’s collection is how personal it is. A number that matters, a phrase that helps during pressure or a character that reminds you to relax can all sit together. The boldest pieces are the ones with a story behind them.

The collection brings together ambition, family, faith and humor. It’s part of the look, but it also shows what keeps Luna grounded as his football career grows.
