Vulkhor is the main villain from Jim Power in Mutant Planet. The ruler of Mutant Planet, Vulkhor came to Earth and kidnapped the president's daughter for whatever reason, taking her with him to the Mutant Planet. Jim Power, the country's best special agent, is immediately sent to rescue the president's daughter, using a transportation device which teleports him instantly to the Mutant Planet. Vulkhor sends his minions after Jim, who defeats them and ventures through the planet, killing Vulkhor and rescuing the daughter.
- Each version of the game gives a different reason for the kidnapping. Vulkhor either wants to turn the president's daughter into a mutant or is holding her for ransom in exchange for Earth's most powerful weapon.
