He's the guy in the green hat. For decades, he was basically just a "Palette Swap," a digital twin of his more famous brother, differentiated only by a splash of green pixels. But if you think Luigi from Super Mario Brothers is just a backup dancer for the guy in the red hat, you're honestly missing the best part of the whole franchise. Mario is the hero we're supposed to be. Luigi is the one we actually are.
It started back in 1983.
The original Mario Bros. arcade game introduced Luigi because Nintendo needed a second player. Shigeru Miyamoto and his team didn't have the memory space to create a brand-new character model, so they just changed Mario’s colors. That’s it. He was a clone. But over the last forty years, that "clone" has developed more personality, more heart, and more genuine human struggle than almost any other mascot in gaming history.
The Evolution of the Green Machine
Luigi didn't stay a clone for long. By the time Super Mario Bros. 2 (the Western version based on Doki Doki Panic) hit the NES, the developers started playing with his physics. He jumped higher. He felt floatier. He had these weird, kicking legs that made him feel distinct. It was the first sign that Luigi wasn't just Mario Plus Green. He was his own thing.
Then came the GameCube era. This was the turning point.

When Luigi’s Mansion launched in 2001, it was a massive risk for Nintendo. They launched a new console without a Mario title, putting the spotlight on the cowardly brother instead. It changed everything. We saw him shake. We heard his teeth chatter. We watched him call out "M-m-m-mario?" in a voice cracking with pure terror. Honestly, it was the most relatable thing Nintendo had ever done. Mario is fearless, which is cool, I guess, but Luigi is terrified and does the job anyway. That’s real bravery.
Why the Internet Obsesses Over Him
You’ve probably seen the memes. The "Luigi Death Stare" from Mario Kart 8 went viral for a reason. There is this perceived darkness—or maybe just a simmering resentment—underneath the "Oh yeah, Luigi time!" catchphrase. It resonates with anyone who has ever felt like they were living in someone else's shadow.
Research into character popularity often shows that while kids gravitate toward Mario, older players and "hardcore" fans frequently lean toward Luigi. It’s the underdog effect. In Super Mario RPG or the Mario & Luigi series, his dialogue often leans into the fact that people don't recognize him or call him "The Green Guy." It’s self-aware writing. It turns a technical limitation from the 80s into a character flaw that makes him endearing.
Differences That Actually Matter
If you’re playing the games, the choice between the brothers isn't just aesthetic.

- Jumping Mechanics: In almost every iteration, Luigi has a higher vertical leap. This makes him better for speedrunning certain levels but harder to control because of his "scuttle" or lack of friction. He’s slippery.
- Hitboxes: Because he's taller and thinner, his hitbox is different. In some Smash Bros. iterations, this is a distinct disadvantage, but in platformers, it can help you reach ledges Mario can't touch.
- The Personality Gap: Mario’s personality is "Hero." Luigi’s personality is "Reluctant Hero with Anxiety, a Poltergust 3000, and a surprisingly good singing voice."
The "Year of Luigi" and the Financial Reality
Back in 2013, Nintendo officially declared it the "Year of Luigi" to celebrate his 30th anniversary. They released New Super Luigi U, Luigi's Mansion: Dark Moon, and a special edition 3DS.
Ironically, it was a financially rough year for Nintendo.
Critics joked that Luigi brought his trademark bad luck to the company’s bottom line, but the reality was more complex. The "Year of Luigi" actually solidified his cult status. It proved that he could carry a sub-brand. Luigi's Mansion 3 on the Switch ended up selling over 13 million copies. That’s not "sidekick" numbers. Those are "A-list superstar" numbers. He isn't the "B-team" anymore.
Misconceptions About the Green Stache
People think he’s just a coward. That’s the common take. But if you look at the lore—yes, there is Mario lore—Luigi has saved the entire Mushroom Kingdom multiple times. In the Super Paper Mario storyline, he’s actually prophesied to be the instrument of destruction (Mr. L, anyone?). He has a range that Mario simply isn't allowed to have. Mario has to stay the face of the company. He has to be perfect.

Luigi is allowed to be weird.
He’s allowed to be clumsy. He’s allowed to have a ghost dog named Polterpup. He’s allowed to be the protagonist of games that feel like mild horror movies for kids. Because he isn't the primary mascot, the developers at Nintendo (and EAD) have always felt more comfortable experimenting with him.
What to Do Next if You're a Fan
If you want to appreciate Luigi from Super Mario Brothers beyond the surface level, stop playing the mainline Mario platformers for a second. Go back and play Luigi's Mansion 3. Pay attention to the animation. Notice how he reacts to every room he enters. The way he touches walls, the way his eyes dart around—it’s a masterclass in character acting through gameplay.
Also, check out the Mario & Luigi superstar saga series if you can find a way to play them. The chemistry between the brothers in those RPGs is the definitive version of their relationship. It shows that despite the shadow, Luigi loves his brother, and Mario is his biggest supporter. It’s wholesome. It’s genuine.
Actionable Insights for the Luigi-Curious:
- Master the Physics: Next time you play a game where he's an option (like Super Mario 3D World), pick Luigi. Practice the "slide." Learning to compensate for his lack of traction will actually make you a better platformer player overall.
- The Completionist Route: Seek out the "Lost Levels" (the original Japanese Super Mario Bros. 2). This is where the mechanical difference between the brothers was first codified. It’s brutally hard, but it’s history.
- Observe the Details: Watch the 2023 Super Mario Bros. Movie again. Notice how Charlie Day voices him. The movie leaned heavily into the "damsel in distress" trope for Luigi initially, but his eventual payoff alongside Mario captures that 40-year character arc perfectly.
Luigi is the everyman in a world of super-soldiers. He’s the guy who shows up even when his knees are knocking together. In a world that constantly tells us we need to be the "Number One," there’s something deeply comforting about the guy who wears Number Two with pride—and then jumps higher than the first guy anyway.
