Marchionne

One of the main characters from Mario: The Music Box ARC.

Described as pretty serious and unemotional, Marchionne spent most of his life inside, reading books and studying.

He is also considered as a past version of Mario.

"Then...prove it to me. Prove to me that you're determined! Uccidimi! Show me that pride! If you are not committed enough, then I shall kill you where you stand!"
-Marchionne, Insane Route
