We know Mario and Luigi are, it was stated by Nintendo sometime. But what about Wario and Waluigi?
Personally, I'd guess it's likely they're the same. Their names and physical characteristics are similar enough to Mario and Luigi's to indicate a shared nationality/heritage, and the Wario series has never been a stranger to ambiguously Italian or Italian American characters like those in Wario Master of Disguise.
But what do you think? Is Wario Italian or Italian American like Mario and Luigi are?
