While Gar was placed in a trance by Goode Goggles, an illusion of Monkey manifested itself in his mind. Monkey claimed he was actually a monkey god responsible for giving Beast Boy his powers, which he said were in part magical rather than solely the result of the Martian blood transfusion.
Greg Weisman has stated that Monkey was the writers's way of introducing the concept of The Red into Earth-16. In the comics, The Red is a mystical force connecting all animal life. Though he is not sure if they will ever directly call it The Red, he felt there needed to be more to Beast Boy's origin to explain why his shape-shifting defied conservation of mass, unlike typical Martian shape-shifting.
