No, Mario and Luigi boy are the only characters. A better question is, why would you want to play as anyone except Luigi boy?
How to you play as Luigi
The Characters starred in Super Mario Galaxy 2, are the same in Super Mario: Mario Luigi, Peach, Toad, and the other character that will star in the game, Yoshi.
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.
luigi and Mario . luigi and Mario . lugi and Mario.
Get 120 stars with Mario
Yes, Luigi is playable in Super Mario Galaxy. You unlock him after getting all 120 stars as Mario.
umm, first of all i think you mean super MARIO galaxy and second the only playable characters are Mario and luigi after you beet the game.-killa765 =)
Mario Luigi (Beat the Game)
Luigi lives in a Mansion and Mario lives in a House
Yes, You can play as Luigi in Super Mario Galaxy 1 & 2. In Super Mario Galaxy 1, however, you need to really want him. He'll only be playable after collecting 120 stars with Mario (Double what's needed to beat the game).
no but u get to see him
(The hey is wrong with you?) No, you cannot kill Luigi in Super Mario galaxy. (He's too precious)
Wario is not in mario galaxy 2 but luigi is.
