Mr. B

Mr. Bug, known simply as Mr. B, is the eponymous antagonist of Pikmin: Wrath of Mr. B. He rose to power on PNF-404 by creating an army of mind-controlled bugs to take the planet over with and force the Pikmin to do his bidding, which Olimar would not allow. Olimar eventually confronts Mr. B in his fortress, converted from an old car, complete with traps and guards. Furious, Mr. B calls upon the Mother Dweevil to destroy Olimar and his Pikmin friends. After his defeat, Mr. B is revealed to be Louie, who developed the ability to control bugs with his mind and decided to use it to stop anyone from pushing him around anymore. He is then sent to Hocotate Federal Prison for his crimes. Mr. B's name and appearance are derived from those of the Super Paper Mario antagonist Mr. L.
