Radium Rebel

Radium Rebel, real name unknown, is a pirate radio host incel spreading Nazi ideals and other such horribly misguided views in the form of a green goop kaiju created by The Boy Who Cried Godzilla. He debuts in the Council of Creators: Side Stories episode The Creators Battle Intolerance.

Appearance
Radium Rebel is a strange skull-like object with red eyes secreting a body of putrid green goop. When he is enraged enough, he produces enough grease to grow a wispy neckbeard.

History
After a lifetime of being scorned by girls with boyfriends not giving nice guys like him a chance, he became a hateful advocate for each type of person having their own national homeland, and revoking of the rights of women to combat the gigantic Jewish conspiracy. He began to operate a pirate radio station to spread his lies, which caught the attention of the Council of Creators, whose varying sexualities and ties of friendship made Radium Rebel shrink away to nothing.

Trivia

 * as acknowledged in the episode, he is a stand-in for general negativity in the world, and how it can only be truly combated with kindness and tolerance.
