Midbus

"What?! Nobody pressed dance! You are broken!"

- 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 was tasked with guarding 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 gives unnecessarily long names to various weapons that he uses. Given his physical similarities to Bowser, he may have been created as a foil to the Koopa king.

Mario & Luigi: Bowser's Inside Story
When Bowser meets Fawful, he sends Midbus to battle him. During the battle, Fawful unintentionally teaches Bowser how to use his action commands on Midbus. Due to the effects of the Vacuum Mushroom, Bowser ended up getting weakened, and Midbus and Fawful abandon him, but not before telling him that they plan to take over his castle.

Later in the game, Fawful puts him in charge of Bowser's Castle, his now secondary base, along with Bowser's now brainwashed minions. When Bowser approaches the castle, Midbus makes it animate to attack him. In a scene of delicious irony, he lands the castle on top of Bowser. Bowser then becomes giant thanks to Mario and Luigi. Midbus fights Giant Bowser within his own castle. After being defeated, he retreats with the castle into a new area. He later drops an enormous iron ball on Bowser, but he is able to toss it back, preventing the castle from moving any further.

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, which Bowser can inhale. 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 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, furry 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. He can jump onto a gigantic snowball and try to roll over Bowser with it. There is a Bob-omb sticking out of it which Bowser must punch to make the snowball explode. After Midbus' HP is halved, he sometimes hides the Bob-omb so the player will have to remember where it is.

Midbus can also send Snawfuls out of his crown to attack Bowser. They can also throw little snowballs at Midbus to make him recover HP. Bowser can inhale them. Midbus also attacks by using snowballs. If he looks at the snowball, he won't throw it at Bowser, but if he looks at Bowser before throwing it, it will go towards him. Then, Midbus will attempt to punch him. It can be countered, as usual. Once again, he attacks by body slamming Bowser. 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, leaving only Fawful to contend with. 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 his body.
