Le Bougne (pronounced Le Bw-Ag-Nu) is a French guy who hates foreigners. He is basically racist. He will scream out names and create cyclones to absorb them and carry them off to Jorgey knows where.
He once had it in for a boy called Ledoong, and he became a French teacher just to get to him. He stood at the front of the classroom and screamed his name, making a cyclone, by going "Leeeeeeeeeeeeeeeeeduuuuuuuuuuuung!"
Ledoong was able to resist the cyclone however, and took up the Risk Dagger, impaling Le Bougne with it. Le Bougne then had to crawl away to attend to his injuries.
The Maths Mafia offered him a position in their inner circle, which he accepted. He know serves as their hunter-killer. All he needs is a name, and then they are dead.
Le Bougne himself, however, met his match during the War on the Maths Mafia - after being dispatched to aid Chosen Juan in a battle against Mr. Rage, Le Bougne arrived on the scene of the Duel for the Golden Crossbow only to be hit with a stray bolt from the Golden Crossbow itself, awarding Mr. Rage with the 'Sticks and Stones' medal he had been lusting after this whole time.
