You listen. Peach, gone. Lord Fawful, new ruler. Now, no need of you. Lord Fawful says sleep. NOW YOU SLEEP!
~ Midbus to Bowser

Midbus is the right-hand of Fawful and the secondary antagonist of Mario & Luigi: Bowser's Inside Story. He is a strong, pig-like creature with two big tusks, an armadillo back with a line of spikes and cuffs like Bowser's, but with small spikes. He is not that bright, this seen in his sentences that don't make sense usually. He is first seen when Bowser regains consciousness in Cavi Cape after he inhales Mario, Luigi, Peach, and the inhabitants at Princess Peach Toadstool's Castle. He is the first battle Bowser has in the game.


After finding out that Fawful is the person who fed him the Lucky Shroom and wants to conquer the Mushroom Kingdom, Bowser quickly attacks him. Midbus enters and pushes him back, saying that he is foolish. Bowser does not like what he hears and the battle commences. During the battle, Fawful gives a tutorial and alerts Midbus about Bowser's attacks. After Bowser takes a hit from Midbus, he feels cruddy from swallowing the Lucky Shroom. Midbus sees how weak Bowser is and exclaims that its pointless, and says he should challenge him again when he gets stronger. Fawful then tells Bowser that he will now take over his castle first, then carry out the rest of his plan. They leave headed toward his castle, with Bowser following all the way. He then confronts Midbus inside Bowser Castle during Fawful's performance where he and Midbus were fighting in a cage. When Midbus is defeated, Fawful then uses the Boos to make Bowser chubby by forcing him to eat a lot of the food Fawful made for whoever won the battle. Midbus is then seen along with Fawful when he changes his plan by getting Princess Peach out of Bowser's body in order to get the Dark Star. He then provides a treadmill below Bowser and then walks away as Fawful was struggling to carry Princess Peach, making Fawful angrilly call out Midbus for help. When Bowser finally explores the depths of Peach's Castle (which Fawful now controls), he confronts Midbus for the final time. However, Fawful upgrades Midbus to a stronger version of himself known as "Blizzard Midbus". When Blizzard Midbus is defeated, his entire body except the head freezes up. You can access the Airway when this occurs. After Fawful and the Dark Star's defeat, it is unknown what happens to Midbus afterwards.


Midbus is shown to be dimwitted as he is shown to speak in sentences in poor English, but is full of pride as he was a rival towards Bowser in terms of strength. He is also shown to be very gluttonous as a pig as he was shown to be eating food thrown by the crowd watching him and Bowser fight. He was also loyal to Fawful and very protective towards him. However, in the end, his persistence became his undoing.


Midbus has the appearance of the combination between a boar and an armadillo. He is pink with a boar face, black horns on the side of his forehead, and a light yellow backside. He can also curl into a ball similarly to an armadillo. When transformed into Blizzard Midbus, he turns blue in color, and his backside grows a fur coat, like a mammoth. He also gains a crown to shoot out Snawfuls to help him fight against Bowser and regain health.


You. No longer Needed. Here, you taste defeat.
Sense is for the weak! You listen. Peach, gone. Lord Fawful, new ruler. Now, no need of you. Lord Fawful says sleep. NOW YOU SLEEP!
You are weak. Most weak. It does not end here. Work on your skills.
You have come. As I expected. Now it is time. Now we will fight! Then you will lose! Then you will cry!
He is very round. I am amused!
Now you face hot wrath. The hot wrath of my freezing blizzard attack! Here your long journey ends!
Though I fall here, none beat Lord Fawful. Now he will finish you!
