Midbus

"Go be trashy in this trash hole with this trash robot forever!"

- Midbus

Midbus is a brawny, unintelligent, anthropomorphic pig in Mario & Luigi: Bowser's Inside Story. In lieu of working to conquer his own kingdom, he is a minion of Fawful, who robotized and guarded Bowser's Castle, as well as fighting Bowser three times. Akin to his master's tendency to speak in Engrish, Midbus speaks in broken sentences that make little sense, and give unnecessarily long names to various weapons that he uses.

Mario & Luigi: Bowser's Inside Story
When Bowser meets Fawful, he sends Midbus to battle him. Fawful teaches Bowser how to use his action commands on Midbus. Soon Bowser gets weakened by Midbus.

Later in the game, he made Bowser's Castle animate. He lands the castle on top of Bowser. Bowser then becomes giant thanks to Mario and Luigi. Midbus fights Giant Bowser with the castle. After being defeated, he retreats with the castle into a new area.

When Bowser reaches the castle, he realizes it's been completely changed by Fawful. Bowser finds out that he made a piece of Bowser's castle into a gigantic auditorium with a big stage at the end of it. Fawful is seen hosting some kind of show or act. When Bowser is about to fight Fawful, he sends Midbus to battle him again in a cage match. In this battle, Midbus attacks in various ways. He can attack by trying to body slam Bowser or tackling into him. He can also punch and do other various attacks. When he attacks Bowser perfectly, food and coins will be thrown to him. Midbus can then eat the food to recover HP. Bowser can do the same thing by doing a good move on Midbus, though he will only gain coins. After Bowser finally defeats Midbus, he is rewarded with a banquet feast. He gets overstuffed though and gets stuck in the floor.

Later in the game, Fawful and Midbus see Bowser stuck. Midbus brings out a treadmill, which Bowser falls onto and uses to make himself normal-sized again.

In Princess Peach's Castle, Midbus makes a trash monster to attack the Mario Bros. so they can't pass to rescue Bowser who is knocked out. After the defeat, he goes into another area of Princess Peach's Castle.

Blizzard Midbus
When Bowser meets with Midbus again, Fawful powers up Midbus, changing him into Blizzard Midbus. In this form, Midbus is completely blue, with a brown back, wearing a crown, and is a lot stronger than before. Bowser has to battle Midbus in this form, which is difficult since Midbus can now use ice attacks, thanks to the power-up. He can jump onto a gigantic snowball and try to roll over Bowser with it. There is a Bob-Omb stuck in it. Bowser has to punch the Bob-Omb to make the snowball explode and make Midbus lose HP. Midbus can also send Fawful Snowmen out of his crown to attack Bowser. They can also throw little snowballs at Midbus to make him recover HP. Midbus also attacks by using ice powers and once again, body slamming into him. Bowser's Fire Breath can cause a lot of damage to Midbus. After Midbus is defeated once again, he gets frozen in a gigantic block of ice. He then begins pumping out an infinite stream of frosty gas from his snout. Bowser needs to use the gas to help the Mario Brothers progress inside of Bowser's body.
