#either he calls himself ''Wario'' because Mario got well known and he wanted to ride that wave of popularity

Okay okay! !!! What if!!! .... What if Wario's background in the Movie-Verse is a reverse-isekai.

Wario's a prolific swindler who's been banned from more kingdoms than he can count. After his hundreth failed scam his long-time partner (soon-to-be Waluigi) ditches him, and Wario is left at the end of his rope and a little exhausted with the whole rigamarole.

Then he takes a wrong turn in a busted warp pipe and ends up in Brooklyn. He looks around at the abrasive behavior, streets littered with garbage, advance-fee loans, phishing scams... rental escalation... minimum wage rates... health insurance... and is like "oh, these are my people!!!"

He quickly makes himself at home and becomes fast acquainted with the ins and outs of underhanded business. At first he attempts to hide his physical differences, but soon decides to make his odd appearance part of his branding as he builds his own companies upon the fine line between "legal" and "illegal." Every so often he'll visit his old world to try out some of the "tricks" he's learned until one day, inevitably, he and Mario end up crossing paths.
