A thin, wiry man named Professor Nafsu had finally done what seemed impossible: invent an Elixir of Life! One good quaff of the Elixir could make a man immortal. The potion was invented so that astronauts could survive trips into space requiring hundreds of years to complete. But word of the miraculous invention fell upon greedy ears. Evil interests sought to acquire the formula for their own selfish ends. One day, Professor Nafsu was kidnapped by rocket ship to a remote tropical island where a masked business tycoon, posing as high priest of Order of Bali, sought to wrest the formula from him. The plot failed, thanks to Astro Boy… and to a harmless little bottle of castor oil!
