One day, excitable Mr. Pompous was relaxing at home when suddenly a mysterious ship crashed through his front door. Clearly the ship was something from the future. A door opened and out stepped a boy in strange garb. His was not a space ship from another planet, he announced, it was a Time Machine from the 23rd Century! The boy was Teddy Tyme and had come searching for his Father. The shame of it: his Father was a brilliant scientist, who had perfected a Time Machine not for Good, but for Evil; for the man was using the machine to travel back to prehistoric times. From each age, he would seize plants, animals-even primitive people! – then place them on display for profit in his own era! Shocked at hearing the story, Mr. Pompous and Astro Boy decide to join Teddy in his travel back through time. They hurtle backward through the eons, back at last to the Ice Age. Here they are ambushed by a curious tribe of tailed human beings, who take them prisoner. Here, too, they meet Teddy’s greedy Father. Showing Father Tyme the folly of his ways, and escaping the wrath of the prehistoric people, becomes perhaps the most unique challenge of Astro Boy’s amazing career!
