No. Mario and Luigi are brothers, and Waluigi and Wario are brothers. Wario and Mario; and Luigi and Waluigi are no related in any way. they are only rivals.
Luigi is Mario's brother. Waluigi is Wario's brother. They might all be brothers, though.
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.
noNo. Mario and Luigi are brothers. They are cousins of Wario. Waluigi's relation to them is unknown but he is suspected to be Wario's brother.
Yes: there is Yoshi, Mario, Luigi, Wario, Peach, Daisy, Toad, and Waluigi.
Wario and Waluigi are brothers. They're the evil opposites of Mario and Luigi.
I'm not sure, but Wario is Mario's alterego. As the same with Waluigi is Luigi's alter ego. they never have said that they are related, but there are rumers that they are.
WARIO IS COUSIN and they are RIVALS
they are brothers but they are half-brother luigi is Mario brother and waluigi is wario kind of brother but i don't know for sure but some people think that luigi and waluigi are brothers but again i still don't know for sure but i do know this Mario,luigi,wario,andwaluigi are all related.
They are not really related. Walugi is the evil version of luigi and wario is the evil version of Mario
You flip the m in mario up side down to make it wario and you just add a wa to luigi for waluigi.
Waluigi is Luigi's enemy. Just like Wario is Mario's enemy.
