My best guess is, according this comic’s author, the princesses only exist as romance objects for Mario and Luigi. Since Wario and Waluigi are a couple, there is no reason to give them princess sex objects. The princesses apparently are not character in their own right to get mirror versions of.
I don’t get it. There aren’t waprincesses because waluigi and wario are in a relationship? What?
