Maurice's origin story was briefly explained in the opening of "Requiem for a Wet Dream". According to Maurice, he was born when a blue alien comes to Earth and proceeds to have sex with the Earth, creating mountains, rivers, and volcanoes.
In "The Head Push", Maurice is having a conference with Connie. It is revealed that two have had a long history together. The Monsters had their first kiss together on Pangaea when the dinosaurs just left on their spaceship. With the dinosaurs gone, Maurice and Connie had the planet to themselves.
