Prof. Svengalie (villain, introduction, death); Tao (villain, introduction); hunchback (villain, introduction); army of robots (villains, introductions)
Professor Svengalie creates an army of giant robots and sends them to destroy bridges. He captures Torch and Toro and places them in a large glass bowl. The author of this story seems to think that an atom smasher literally destroys any atoms it comes into contact with, as Torch and Toro rock the glass bowl into the atom smasher and it is destroyed. When Professor Svengalie tries to ax murder Toro, he stumbles into the atom smasher and is killed.
