Mario & Yoshi: Mushroom Kingdom Heroes
Mari-Robo's debut appearence is in the 2017 game Mario & Yoshi: Mushroom Kingdom Heroes. He first appears as the boss of World 4, Geartropolis. According to the Gearmos in the city, Mari-Robo has been dictating them so they could make traps in the factory he rests in to keep Mario and Yoshi from getting the 5th Star Key. During the fight against him, Mari-robo flies around the arena, shooting cannon blasts and occasionally throwing bombs at the duo. To defeat him, Mario must pick up the bombs (or Yoshi can eat the bombs) and throw them at the robot. Mario can also just use his own bombs as Bomb Mario to defeat him. Once that is repeated 4 times, Mari-Robo starts malfunctioning and falls off the stage, dropping the Star Key.
At the end, when the book turns to the page for World 4, Mari-Robo is seen badly damaged, with Gearmos celebrting around him.
Despite this, on one of the levels of Star Carnival, the secret world, Mari-Robo is seen again, this time with an upgrade. His color seems to be changed, making him resemble Fire Mario. His jetpack generates stronger fire, and his cannon blasts are a lot bigger, making his attacks harder to dodge. Mario and Yoshi can't attack him, as he is in the background, so they can only run away and dodge his attacks. However, at the end, he gets crushed by a rock, possibly destroying him for good.
He is set to appear in future ChaoticYoshi games.
Mari-Robo greatly resembles Mario, with a few notable differences. His "skin" is metal-colored, his shirt and cap are darker than Mario's red, his overalls are black (similar to the NES sprite of Mario in Super Mario Bros. 3), and his gloves are black as well. He also has an arm cannon, and a jetpack. He appears to be made of metal, as if Mario tries to jump on him, he bounces off with a metallic "clank" noise.
