Anthem is a pale 'human', with a grey turtleneck, dark pants, and brown shoes and hair. His eyes are mostly black, with only his pupils showing as white dots.
At birth, Anthem O. Apollo was cursed by a mysterious anomaly named Atathir. This being resents the correctness of humanity, and at one point broke the barrier between life and death and destroyed the entirety of Planet Earth in another universe. Over the course of his life, Anthem noticed changes to his body, slowly turning less and less human in appearance as time went on. This led to him being considered an outcast by everyone around him, and so he went into hiding at adulthood. He lived most of his life resenting the rest of humanity as part of Atathir’s plan to make the perfect weapon of universal destruction. Thankfully, Anthem did not go down that dark path thanks to his new friends.
Anthem would soon come face to face with boyfriend during the events of Rigatoni Rappin, in which he would have Shitass and Zavion as support during the encounter. Soon, he would be brought to Endgame, and now currently resides in the cave, along with his buddies.
