Mario

Mario is a primary antagonist in Smush Bros and a henchman of Princess Peach. He is first mentioned in Chapter 1 as having disappeared to retrieve eggs. Mario next appears on Ridley's Planet, disguised as Dark Samus. There he kills Ridley and attempts to assassinate Luigi. He is stopped by Zero Suit Samus, giving Luigi time to escape before he killed her.

Mario leads Peach's army to attack The Vault during Chapter 10, now wearing a purple hat. There he prepares to fight Luigi again, but is transformed into Sonic when Wario breaks The Prophecy. Mario knew about The Prophecy and The Egg, being the first to remark that Wario has broken it by fusing with The Egg.
