The Pirate of Time Castle: Part One
A mysterious caped man appears on the 999, who stops a fight between two men and later rescues Tetsuro from another man. The 999 arrives at the planet Heavy Melder where Maetel and Tetsuro split up. Tetsuro wanders to a bar where the bartender tells him of the Time Castle, which is supposedly ruled by Captain Harlock. Tetsuro also meets Leryuzu, a singer who is sister to Ryuzu (episodes 7&8), who tells him that Maetel has headed to the Time Castle.

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.
