Why does Mario still have his Italian accent

[Mount Wario]

He's barely been in Italy throughout his life. No one in the Mushroom Kingdom even speaks Italian. I don't even know why he can speak the language so fluidly.

 

[Ray Trace]

Maybe he was raised in a community with Italian speakers who have the accent? I mean, he had the accent as Baby Mario too.

 

[Mount Wario]

Unless he were to be uncle Mario from Ass Creed 2, I don't think so. Who else speaks italian besides him and his brother there?

 

[Czario]

I guess he grew up in a section of Brooklyn with a lot of people who had come from Italy or whose parents had come from there.

 

[Mcmadness]

You may as well ask why any of the characters speak the language they do. It's a moot point.

 

[LeftyGreenMario]

It's part of Mario's character. He looks like a silly cartoon man, why not give him a silly, playful voice too?

My headcanon is that the little Mushroom village where Mario and Luigi were raised in after the events of Yoshi's Island were prominently Italian speakers,

 

[Vivian]

My dad's side of the family is Italian and I can assure you, it's not a normal Italian accent.

Also that seeming random gibberish he says in the M&L games are definitely not Italian.

 

[Thomas the Tank Engine]

My headcanon is that he's just putting the accent on to fit character.

Naturally, his real accent is RP.
