| Dr. Broome
| Supervillain Information
Dr. Broome is an evil scientist and a supervillain.
Radioactive Man once encountered Dr. Broome but he got away. It was later revealed that he used the Trans-Spatial Stairclimber to escape to 100 years in the past. When in the past, a robot, Shootin' Irons, came out of nowhere, Dr. Broome fixed him up and put him in a time capsule with the orders to kill Radioactive Man 100 years in the future. Eventually, the effects of the Trans-Spatial Stairclimber wore off and Dr. Broome went back to his present.
Radioactive Man reprogrammed Shootin' Irons and had him take him to the lair of Dr. Broome and Dr. Crab, who Broome was working with. Radioactive Man and Fallout Boy then defeated the pair of villains.
Dr. Broome's Trans-Spatial Stairclimber was being held at an abandoned government cheese warehouse. Someone stole it from the top-secret government lab and used it to bring Radioactive Ape, Radioactive Man-Beta, Radioactive Boy and Glowy to their universe.
