Apopolapse Bloon, the Warbringer, inserted a microchip into Ironbloon's suit when he wasn't looking to corrupt his Vibranium Core, causing mass brain damage as well as corruption to Ironbloon. Now he sweeps from the skies, slaying monkeys, destroying machines, and detonating buildings. (Please note that I only know of Iron Man tracely, and as such, the skills may be slightly off.)
