The younger brother of Nintendo's duo known as the Super Mario Bros. He is taller, wears green, and isn't as fat. Proven in Super Mario 2, he can jump higher. Starred in 2 games, 1 of which is often overlooked because he didn't have his name in the title, that was Mario Is Missing, and of course, Luigi's Mansion. Has less followers but is cool nonetheless.
Luigi is oftentimes better then Mario in most of the new games coming out.

Oi, this guy is an underrated Italian. He's often upstaged by Mario, and needs more attention. Luigi is definately a great guy. He's just got a crappy job: The second fiddle to a fat Italian bastard named Mario.
Whoo!!! GO Luigi! He's definately the best!

Luigi is generally viewed as the lesser known of the Mario Brothers who occasionally makes a cameo appearance in Mario games and rarely stars in games himself. Luigi often serves as the second player character in Mario games. However, this is not because Luigi is less capable or less popular. It is because Luigi has got more important shit to do than save his brother from turtles and dragons all the time. In fact, these is some question as to whether Mario's "enemies" actually exist or if Mario is just on a perminant acid trip. Luigi only appears in Mario games after Mario dies because Luigi is only there to bail Mario's ass out of difficult situations. Luigi actually served 10 years as a green beret in the United States Army (thus the green hat) and is capable of beating the living shit out of Mario or his foes at any given moment, but likes to see his brother sweat a little. The reason that Luigi's army status is not widely known is because most of his work has been classified, but Luigi has actually ben credited with the such infamous feats as the asination Archduke Franz Ferdinand of Austria, thus beginning WWII.
-Hey, who do you think would win in a fight between Luigi and Vin Diesel?

-I don't know thats too tough to answer, but the one thing we do know is that they could both kick the shit out of that pussy Mario.

Always within his older brothers shadow, Luigi is always "Player #2." He likes long walks on the beach, his hat hand washed, and brutally murdering mutant turtle dragons. He'd do anything to get into the spotlight for just once.
"It's-a me, a-Luigiiiiiii!!!!!"

He's a mean green fighting machine. Mario's younger and under-rated brother. Everyone thinks he's cooler than mario. He jumps higher, he's not a fatass, He sucks up ghosts with his trusty dusty polturgust 3000. All Mario can do is run a bit faster. What good is that? He's a fatass too because he's been eating too many pizzas.
"Omigosh Mario is soooo coooool!"
"Fuck Mario! He had to be rescued by his brother TWICE. What the fuck has he done for him?"
"You're right... Omigosh Luigi is soooo coooool!"

*Mario gets captured* "Help me Luigi!"
"Fuck-a-you You piece of-a-shit you a-deserve it. I'm not a-saving your ass again."

Although he is always upstaged by his fat brother, Mario, Luigi is obviously more skilled. He can run faster, jump higher, and doesn't eat as many pizzas. He also sucks nasty ghosts up with his trusty Poltergust 3,000. He can do all of this... and all Mario can do is shoot water at stuff with FLUDD. Luigi isn't just the most underrated Mario character, but the most underrated Nintendo character too.

In 2D platformers, Player 2 is always Luigi. Luigi has only had two games starring him: Mario Is Missing, which shunned Luigi more, it being a crappy edutainment game, and Luigi's Mansion, which was a lot better and introduced the trusty Poltergust 3,000. Both of these involved Luigi saving Mario, which shows how lucky that fat-ass is.
Mario: "Luigi! Help! The Boos are taking me away again!"

Luigi: "Too bad, you ungrateful fat-ass! And if you get back, I'll beat your sorry ass!

Luigi is the younger but taller brother of Mario. In Paper Mario you can read his diary where he mentions that he is terrified of boo's and that he wants to go on his own adventure. In the sequle Paper Mario and the thousand year door his wish to have his own adventure comes true. Luigi recived a letter that says Princess Eclair of the Waffle Kingdom was Kidnapped by the evil chestnut king and that they needed his help. He has to find the seven pieces of the Marvuilse compas to find Princess Eclair. In the game you can even buy a series of books based on his adventure. When Mario talks to Luigi he tells him about how he likes Princess Eclair so Daisy is going to have to find another man.
"I hope they come out with a Paper Luigi."
"Yeah that would be fun."
