Adamantine

Most people in the Trickroom universe, upon learning that deities can be killed, don't try to actually DO it. Adamantine is not most people.

Adamantine spend their teenage years seeking out information on God, also known as the First Deity, the one who performed the Great Trick to anthropomorphize billions of animals to the level of intelligent species, and upon reaching adulthood, went on a journey to kill them. However, when the other deities learned of this, Adamantine was struck by a trick that scrambled all aspects of their identity–gender, memories, personality, etc.–and now they have to go on a journey of self discovery to find out who they are.

Then they can kill God.
