“Ah, sweet monsieur! 'Elp me! I need 'elp! Helpez-moi, s'il vous plait!”
Broque Monsieur is a block character in Mario & Luigi: Bowser's Inside Story speaking English with a thick French accent and able to speak French itself. According to the Japanese official site, he is the Mushroom Kingdom's leading block collector; he is also a collector of block-shaped kittens called Blitties. Broque Monsieur owns a block-shaped dog named Broggy, and manages a store where Bowser can shop at to get healing items.
 Mario & Luigi: Bowser's Inside Story
An unknown period of time before Broque Monsieur's first appearance, he and Broque Madame dated, but have since separated. This is revealed when Mario and Luigi chat with her.
He is first shown to be stuck on an island while Bowser walks past. He yells for Bowser's help, who only does it for a prize offered by Broque, the Vacuum Block. Broque tells Bowser to grab the rope and pull. At first, Bowser cannot pull the island any closer, but with the help of Mario and Luigi on the inside of his arms, he pulls the island back to the shore. Broque then fights Bowser to help him master the Vacuum Block technique.
He is shown in a battle against Bowser. He explains the "vacuum" command to Bowser. He fights by using items he gets out of ? Blocks. Sometimes he uses a mushroom to recover 30 HP and sometimes he uses a Mega Mushroom and makes himself giant. To counter Broque's colossal attack, the player has to make Bowser punch Broque just as he's about to ram into him. Doing this will make Broque's body be knocked far away from the battle field. While Broque's body is trying to get to his head, Bowser can punch it for extra coins. When being battled, he rotates his head to make himself look more fierce.
Broque also runs his own shop where he sells items for Bowser. He also has some shops around the Mushroom Kingdom in the shape of a block. He owns two different shops. One for gear, mained by Broggy, and one for items such as Syrup. Through the block-shaped shops called "Shop Blocks", Broque Monsieur can release "Negative Ions" to heal Bowser completely at the cost of 10 coins, much like Royal Mushroom Tea for Mario and Luigi.
While Broque is amicable towards Bowser, he has a strong dislike of Mario because he considers Mario's habit of breaking blocks and lowering their "value" to be abhorrent. Because of this, Broque will refuse to sell items to the brothers and impolitely insist they leave his shop immediately and never come back (though he will immediately apologize for his rudeness). Additionally, the Mario Bros.' hammer is not strong enough to hit a Shop Block, thus eliminating the other method of shopping through Broque Monsieur.
 Mario & Luigi: Dream Team
Broque Monsieur is confirmed to return in Mario & Luigi: Dream Team. He is seen welcoming Mario, Luigi, and Peach to Pi'illo Island. Not much else is known about his role in the game.
