The better yet always ignored of the Mario brothers. He's obviously better, I mean, come on, his brother had to be saved by "scaredy-cat" and the supposedly weak Luigi!
"Thank you, Luigi!" "Finally, peaople see that I'M the star!"

Your right-hand bro who's always got your back. Most people think that he's little more than some loser that just tags along with you, but you know that he's there to help you out.

Named after the younger brother of the famous Super Mario Brothers.
Person 1 "Dude, who invited the fricken' geek?"

Person 2 "Back off, man; he's my Luigi."

Luigi Mario is the youngest of the 2. He spouts amazing amounts of attacks. He can run faster and jump higher then Mario. But due to his proness to fear and being quite shy, he isn't really great on adventuring. Many people think that it means Luigi is jealous of Mario, but that's not true. Luigi enjoys taking small jobs like cleaning the house and ACTUAL plumbing jobs.
"Hey Luigi, Can you handle the plumbing jobs that come from when I leave? I'm gonna sign autographs."

Luigi is the kind of guy who would message you in the middle of the night just to tell you a crazy story that happened to him on that day or just to say that he misses you. He knows the right words to say when you're feeling down and he knows when to shut up when you don't feel like talking. He's the kind of guy who would call you when he's drunk and tell you how an amazing friend you are and how he's lucky to have you. He doesn't care if you eat like a pig or if your hair is all messed up. He doesn't mind if you can't sing. Because he loves you for who you are and not for who you're not. He would stay up late for you when he knows something's wrong and will only sleep if he knows you're okay. He would sit down and play the piano if he doesn't feel like talking or just laugh at everything that's getting out of hand. He's one of a kind and if you have a Luigi in your life, you are truly lucky.

A really cool guy who doesn't get as much attention and/or fans as his brother, Mario. Taller and slimmer than Mario, and dresses in green.
Luigi will kick Mario's sorry ass one day.

Marios younger brother. Its pretty sad, because in the mario and luigi game on gameboy, when people see you they say "WOW!! Its mario and green dude!!". Often underestimated as a sidekick to mario but is actually better. He is not as fat, can jump way higher, and is much faster. He finally got recognized as a main characyer in the game Luigi's Mansion, a title released at the time of gamecubes launch. A mario game, super mario sunshine actuallt wasnt realeased until some time later.
Player 1: Damn, Mario wont jump that gap!! Player 2: You should of used Luigi, fuckface!!
