Luigi

“Something's gumming up the plumbing, poor Luigi's in a bind
Giant turtles out to get him, creepy crabs are right behind
Fighter Flies, jeepers, yipes, they're all coming out the pipes
"Mario, where are you?"”

—Disembodied voices & Luigi

Luigi is Mario's well-known brother who often goes on adventures with him. He jumps higher and slides further than Mario does. He's also more cowardly, but that doesn't usually prove to be an issue. Even though he's usually seen with Mario, he's gone on a few adventures without him as well.
