Wario/Relationships

This is a relationship for Wario.

Waluigi
He and Waluigi are brothers in the SMG4 universe. (it is unknown whether they are brothers in official canon or not) The two are the main protagonists of The Wacky Wario Bros. series, where they go on ill-fated adventures in an attempt to get rich. Neither brother is above harming the other to get an advantage, and they tend to fight a lot. After Waluigi went crazy, Wario attempted to continue his scamming without Waluigi, but eventually broke down. He became depressed and went searching for his brother in SMG4: Mario The Scam Artist. After finding him in SMG4: War Of The Fat Italians 2018, the two reconciled.

Mario
Wario is a big antagonist to Mario in The Wacky Wario Bros.: Money Mayhem. In the blooper, Wario is seen putting a bucket over Mario's despite of him trying to rescue Wario, and Mario runs crazy with the bucket on his head. Later in the blooper, Wario attacks Mario in hatred while they are both in the jail cell from getting arrested.

Luigi
Although Wario and Luigi both don't get alot of screen time in SMG4's bloopers, it appears that Wario probably hates Luigi as seen in The Wacky Wario Bros.: The Winning Ticket, where he runs over Luigi when he lost his patience on waiting to get through a street intersection. However, they have been seen singing the Christmas carols with Mario in The Bowser That Stole Christmas.
