The Entity (Catto Boi)

The Entity is an unknown demonic being that only wants to torment whoever he pleases. His initial goal is to take over the world of Catto Boi, before trying to destroy it when he is unable to. He sometimes gets destroyed and kicked from Catto's world, but he manages to come back to life, and uses his warping skill to enter the phase world of Catto Boi, tormenting every single bit of it.
