The Great Chief Cicropros
The 999 stops at an abandoned artificial colony world. Tetsuro is pleased with its appearance but Maetel is puzzled that the colony looks quite different than it did on her last visit. They investigate further, and are set upon by a terrified mob of physically identical men. Maetel recognizes their face as being that of the colony's architect, Dr. Cyclops.

Galaxy Express 999
After witnessing the death of his mother and being left for dead at the hands of Count Mecha, ten-year old Tetsuro Hoshino is awakened by a mysterious woman, Maetal. In exchange for only his company, Maetal offers him the ride of his life on the Galaxy Express 999. It is said that those who travel aboard the legendary train to the end of the line can receive a free mechanical body and with it, immortality.
Impoverished and alone, Tetsuro leaps at the opportunity and joins Maetal on a quest that will span the cosmos. As the Galaxy Express 999 makes its way across our solar system and beyond, Tetsuro is drawn deeper into a dangerous universe where peril lurks at every stop.
