A pretty good history on Wario and his Japanese self.
This article was discussed in another thread. But Im gonna go ahead and quote this from the second point it makes since youre so insistent on making it the ultimate source:
In general, the U.S. interpretation of Wario focuses mostly Wario’s greed and wickedness. In the Japanese version of promotional materials, the focus is on Wario being the clumsy anti-hero
Notice how the focus here is interpretatons and promotional materials?
You got the actual game. Then there's how the countries chose to advertise it.
As in, what's in the game leaves room for both. That's what Wario SHOWS, not what they TELL you about him. its like writing 101 godammit
Hell, if that doesnt cut it for you, im gonna use this as a source, from the guys involved in Shake It's development.
Tsukawaki: After I’d played a bunch of the games in the series, I thought Wario was pretty manly. He’s so uncool that he ends up being extremely cool. Depending on the game, he can be coarse—farting and doing stuff like that, but I didn’t want to show that side of him. As much as possible, I wanted to show a macho Wario, one who is masculine and tough. I asked the animators to emphasize strongly his manly characteristics. We built up this image step-by-step during the animation process.
Japanese people reaching the American conclusion because they played the games themselves? Didnt they watch the advertising!?
...See, they played the actual games to reach a conclusion about how to make Shake It Wario, that's why he works so well. The problem with Smash Wario is that it feels like Sakurai went by the common Japan interpretation of him and didn't do any research beyond that. I don't mind him going for a different interpretation, but in a game that's supposed to celebrate the characters of Nintendo, he shouldn't be so biased by a shallow viewpoint.
I think Shy Guy meant to say it was never in his moveset or important part of the gameplay. I'd call it an idle habit that shows his lack of manners rather than him purposefully being gross.wario scratch his butt when you idle on climbing a ladder in WL3
There's no denying it's part of his character, but it's too small in comparison to others to be the made as the main focus.
