Fictional Team Biography
The Sinister Society were created by Will Magnus to destroy his brother, Magneto and his creations, the Magnetic Men. But, disgusted by the ugly robotic forms bestowed upon them by Magnus, the Sinister Society instead rebelled against their master and set out on their own, hoping to find a way to make themselves look more human, like the Magnetic Men.
After capturing the Magnetic Men and trying to remove their Magnetometers in an attempt to achieve their goal, the Sinister Society eventually joined forces with Magneto, realizing they had a common enemy in Will Magnus.
