Magna Charge is descended from the great Ultron robot race, but was mysteriously created with a giant magnetic head.
This proved problematic, as his peers were all metal and were constantly drawn to him.
As a result, Magna Charge was exiled to a distant island, where he eventually learned to control his magnetic powers. After years of training, he returns home to demonstrate his abilities, but finds everything completely destroyed.
While searching for answers, Magna Charge caught the attention of Master Eon, who realized that Ultron's sole soldier was a perfect candidate for the Skylanders.
