The Monster Fighters theme was introduced in 2012 who's story line is similar to the 1987 movie The Monster Squad, which features the same monsters. In the backstory, the monsters attempt to collect them to unleash doom on the Earth by eclipsing the Sun forever. A band of Monster Fighters, led by Dr. Rodney Rathbone, tries to find the stones before the evil Lord Vampyre uses them to eclipse the sun forever. The Monster Fighters were discontinued in 2012, the same year it was introduced.
