Black Cockroach

Black Cockroach was a cosmic entity known throughout the universe for his neverending cruelty and hatred for all that is happy. He was a powerful adversary that Momoiro Clover Z faced at Kodomo Matsuri 2013, where he interrupted their concert, and set his motion the chain of events that would lead to The Referee's life debt to Momoclo.

History
No one really knows the origins of Black Cockroach. Some argue that he was created as the embodiment of all that is impure in mankind, and others say he was once a prince, who was corrupted by the dark powers of the universe. What is known is that he was feared by all, and that wherever he went he left only death in his wake. Black Cockroach was responsible for the disappearance of cosmic entity Teletama, and kept him imprisoned for over one hundred years, fruitlessly attempting to corrupt him.

Events of Kodomo Matsuri 2013
In 2013 Momoiro Clover Z held a concert for children, wanting to bring joy to the youngest ones. Black Cockroach saw this, and was disgusted by this blatant display of happiness and carefreeness, and thus he vowed to burn the stage to the ground, along with everyone present. He had not, however, counted on just how powerful the girls of Momorio Clover Z were. When he first appeared on stage with his cronies The Ref, in a typical idiotic display of heroism (most likely hoping to win fame and glory), stormed up on the stage in order to stop Black Cockroach. Being no more than a puny mortal, he was easily swatted aside, and just before Black Cockroach was about to deal the killing blow Momoclo arrived to the scene and distracted him. This allowed The Ref to make his escape, and giving him a life debt to Momoclo. After a fierce battle Black Cockroach was temporarily beaten, but he returned in a second attempt at disrupting the show. In the end he was defeated, and his demise led to the release of Teletama, as well as a successful concert.
