Astro Boy: Tetsuwan Atom - episode 35 - 06 Dec, 2003

While wandering in the space-time labyrinth, Rock is saved by the Firebird and returns to Earth. The Firebird is trying to see how Rock would use his power. After returning to Phoenix Island, where ancient ruins lie, Rock uses his supernatural powers to manipulate Dr. Lyon, a scholar who lives on the island, to bring Atom and Dr. Ochanomizu to the island under the pretense that they are there for research. Unaware of this, Atom and Ochanomizu arrive on the island. They go to investigate the ruins with Professor Atami, but he suddenly locks Dr. Ochanomizu in an ancient prison. Atami is a disguised version of Rock. In order to become a super human again, Rock uses Atom. In order to save Dr. Ochanomizu, Atom has no choice but to do as he is told. Finally, the door to become a super human appears in front of Rock. (Source: Wikipedia)
