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.
