The Cavity Demon is the main antagonist of the Season One episode, Meatball Party.


This monster lived in Raven's tooth and was unleashed after the Titans eventually pressured Raven into eating Cyborg's meatball. The meatball had cybernetics in it and they cracked Raven's tooth, unleashing the demon. It would attack and devour anyone (especially Beast Boy) whenever Raven opened her mouth and eventually devoured him. The Titans take Raven to the dentist and it attacks two dentists and devours Robin. It later devours Starfire after Cyborg enrages Raven with another meatball party. Cyborg willingly allows Raven to eat him and the monster is finally revealed. It's victims are shrunk inside Raven's mouth and are overwhelmed by the monster. Cyborg finally defeats the monster by sealing Raven's tooth crack with meatballs, trapping it and presumably banishing it from her.


The demon can attack whenever Raven has her mouth open and cannot when it's closed. When it drags victims into it's mouth they shrink down and confront the demon. It is also strong enough to defeat the Titans and withstand their attacks.It has even enabled itself to bond with hosts,assume humanoid form,gain absolute conditon,and Extreme evil Anti-God Power!!!

The [EVIL] is a Creature or Being of unimaginable and unfathomable power, Not even Gods or Otherworldly beings can ever hold a candle to it's true power or form. Death even fears the [EVIL] as it's life-force is like a never ending reservoir of energy that is truly limitless, Demons cower in it's presence and Angel can't even look it in the eyes. As the name [EVIL] suggests, This creature or Being is the true embodiment of the Omniverse.

However the [EVIL] doesn't fight for a cause, But for something to do out of boredom. Since it can foresee the future nothing can surprise it anymore and fights to just pass the time. The [EVIL] isn't bound by the laws and rules of Reality, because it is far bigger than reality itself. With it's unlimited knowledge and powers, Itt can and will do anything it wants and absolutely nothing and no one can stop it!!!
