There is no official answer, honestly. All we know is they are Mario and Luigi's "evil counterparts." well Mario and luigi are cousins and waluigi and luigi are brothers Mario and Luigi are brothers... and I highly doubt that Wario and Waluigi are cousins with Mario and Luigi.
Mario and Luigi are from Italy
Mario and Luigi are twins.BUT Mario is the older twin.
Well Mario and luigi are brothers but I know Luigi looks taller but Mario was born first and luigi was born second so mario was the first to be made.
Mario is older than luigi

No, there is no such game as Paper Luigi. Although, Paper Mario: The Thousand Year Door does imply that Luigi went on his own adventure while Mario was in Rogueport.
Super Luigi Galaxy isn't a real game but in both Super Mario Galaxy and Super Mario Galaxy 2 you can unlock Luigi and play him.
they ain't real, they have been created by Nintendo as cartoon charactors
Mario and Luigi are twins, but Mario is older.

You can't get Luigi in Super Mario 64, though you can in the DS remake. No matter what all those "L is real 2401" rumors have to say, Luigi is nowhere to be found in the game.
Yes its Luigi.
Mario's name is acutally Mario Mario as established in the Mario Brothers Movie, and in game titles in witch they refer to them as the Mario brothers. Them being Luigi Mario and Mario Mario.
