monokuma
Monokuma is the main antagonist of Danganronpa, and serves as the mascot for the whole franchise. He is the mastermind of the "killing class" that forced his "students" to kill each other for survival.
He is a robotic teddy bear with a distinctive split coloring; the right side is white and friendly, while the left side is black and sports an evil grin.
He is voiced by Ooyama Nobuyo until 2016, and by TARAKO until 2024.
