If any of you played all of the Paper Mario games, you probably had this thought (though I highly doubt it). As those who played Super Paper Mario, you know you can control 4 characters, Mario, Luigi, Peach, and Bowser. 3 out of the 4 were bosses, and also final bosses. In the first game, the first, and final, boss was obviously Bowser with the Star Rod. The second game was Peach possessed by the Shadow Queen. And last but not least Luigi fused with Dimentio to make Super Dimentio.
Notice where this is going? Every playable main character (save Mario) of the third Paper Mario was a final boss (willing or no), and two of them were recurring (Bowser and Luigi). So, if we continue this pattern, will the next final boss be Mario himself? To keep balance will he just be a final boss like Peach, not recurring?
Discuss this theory (I do not claim it as my own).
