Ubbshubboth

Ubbshuboth, The Demiurge, The Selfish Source, an ancient Yagathian entity who is the source of all selfishness, hatred, lust, and immorality.

He conspired to be the head of the Outer Dimensions and overthrow the Astral Masters who he hates because of his jealousy and thirst for the ultimate power.

Mythology
"'Floating through space and time the Demiurge divulges his bitterness and selfishness across the Universe...Ubbshubboth is fuming with selfishness as he can never grasp kindness and empathy for anything...The Astral Masters fought against this contentious mass of pure hate and lust...'"

Ubbshubboth can be either cunning or evil at different times depending on the situation and its reproduction is hindered by the Astral Masters so it will not give birth to an abomination that could potentially destroy the entire Universe.

He becomes a cunning being when trying to give birth to unsuccessful offspring and evil when looking for selfishness and depravity in which he gains power.
