Mario following the rules of Madokaverse. The question is, would the Star Spirits be entirely against Kyubey or be Incubators themselves? Though it does give me an image of Geno being like Homura (and a rebel, if we're going with the Star Spirits = Incubators idea), starting out adorable and naive like Twink from Paper Mario, then slowly growing more serious and Star Piece-focused with each failed timeline.
