It all goes back to Yatterman.
Also, curse Miyamoto for depriving us from a Doronjo-style villainess.
Not content with crushing Paper Mario originality against heroic employee Kensuke Tanabe's wishes, he also took Wapeach from us before seeing the designs. Wario got screwed!
And this is the same Miyamoto that didn't let Mario do the peace sign for 20 years because it was too childish.
Man's got a hate boner for everything he created.
