The brother Mario. People seem to think he's underrated, although he has a lot of fans.
Luigi really isn't that underrated.

A boy usually Italian but Filipino in rare occasions. He can be also known as "The Weegee" for short. His favorite food is pizza (Costco) and he most likely plays Xbox 360 instead of PS3. A Luigi has really good hearing so don't talk shit about him cause he'll hear you from a mile away! Its ironic but most Luigis' favorite color is actually Green like Luigi from Super Mario Bros.
Boy 1: Hey did you see Weegee today?
Boy 2: Yeah, he had Pizza from Costco for lunch as always

Boy 1:*whispers into Boy 2's ear* So I hear Luigi likes food, ALOT.
Luigi: Da Fuq You Say?

Boy 1: See Luigi with his green sweater today?
Boy 2: He had HELLA SWAGGGG

the sexiest gaming mascot alive-kiks mario's sorry fat ass by a lot. Has one of the best games ever-Luigi's Mansion. EVERYone underestimates the gaming hottie. Mario should be the side kick--he's slower, fatter, and a lousy jumper. Luigi's jumps are super long! GO LUIGI!!!!

It's-a-me, A-Luigi! Lets-a Go!!!! mama mia

The underrated Mario Bros who twice his older brother's ass; first in "Mario is Missing", then in "Luigi's Mansion" and maybe a few more times in the animated series in the late 80s and early 90s. Luigi can jump higher, he can perform critical hits with his upper cuts and shoots out green straight-shooting fire balls (as witnessed in Super Smash bros games). However, Luigi is not as fast, as physically strong (when it comes to lifting and carrying things) and he does not have a good sense of balance as Mario, (making him harder to control) as witnessed in SMB 2.
Luigi is usually the unsung hero of almost any Mario game
