He was born like a normal baby, except for the fact that he weighed over three-hundred pounds. Although slightly heavier than an average seventy-five pound newborn, Isagi was a normal size. The Overlord soon learned of this unique child and decided to let him live, for a very selfish reason.

The Dark Overlord needed an heir to his power. He knew that he was nearly immortal, but he also knew that he wouldn't be around forever. He took the young Isagi from his parents and began to shape him into an Overlord's image - one of an utterly ruthless creature.

Isagi grew very quickly, but acted naively around others. At the age of fifteen, he was put through a series of tests developed by the Overlord.

The tests showed that little Isagi was much like the Overlord - highly intelligent, devoid of emotion, and possessing a weight of over two tons. Instead of acting highly emotional, slightly confused, and weighing under five hundred pounds like a normal Anterran teenager.

Isagi's powers were also clearly more powerful than any other Anterran's. The pattern had repeated itself, except for one ability. The tests didn't find Isagi immune to the Overlord's mental dominance, nor that he could stop the Overlord's control of others.

Isagi's immunity caused problems. Well, at least his immunity caused problems for the Dark Overlord's plans. Ever since the Overlord had been in power, he had wanted to rule the planets near his own.
