ya i think there blood brothers
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.
The idea of Weegee comes from luigi from super Mario so yes.
Thery are brothers.
They are not really related. Walugi is the evil version of luigi and wario is the evil version of Mario
Luigi is Mario's brother. Waluigi is Wario's brother. They might all be brothers, though.
They are sisters so they are related like Mario and luigi
Mario and Luigi are twins, but Mario is older.
luigi and Mario . luigi and Mario . lugi and Mario.
Yes its 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.
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.
Luigi is Mario's younger but taller brother.
