He could be, nothing proves this or denies it.
Probably Wario.
They don't have one. Like Mario and Luigi don't have one. I don't know what Wario and Waluigi's last names are, but I know that Mario and Luigi have last names: Mario Mario and Luigi Mario. That's why they're called Super Mario Brothers.
Mario has no last name and neither does any of the people in the Nintendo gang. I am the creator of Nintendo and everybody ask me whats their last names and heres my answer they don't have one. thanks and keep on playing my games sincerley, Dr. Henry H Eison *****Personally I would think that Mario's last name is Mario and luigi's last name is Mario because they are the Mario brothers <3 Jessica
the reason wy waluigi hate poor little luigi is because he finds luigis generosity and kindness to be sickening. i realy dont like waluigi much.... i just think he needs to get to know luigi a little better....thats all...plus wario is marios rival so waluigis gotta be luigis rival.
waluigi wario is his last name
waluigis not in the game
You flip the m in mario up side down to make it wario and you just add a wa to luigi for waluigi.
I think it isgetting hurt because he could get smashed or smoshed
