Beast Boy's parents, Mark and Marie Logan, were geneticists that would travel the jungles of the world to study their wildlife. Beast Boy was brought up in the jungles of Brazil, Africa, India, and several other places. The Logans particularly became interested in a rare species of green monkeys, but the day they finally found them, something terrible happened. Beast Boy was bitten by one of the monkeys and contracted a serious illness called Sakutia. To save him, his parents attempted to cure him with a new serum. His skin, hair, and eyes turned green, and he was also bestowed with shape-shifting abilities.
