After being sucked into the Dead Universe, Nova was chosen to be the host for the Darkness, an otherworldly counterpart of the Matrix of Leadership which worked by transforming the inhabitants of the Dead Universe into undead wielders of anti-life. Upon merging, Nova was reborn as the sinister and extremely powerful Nemesis Prime. He now sees it as his mission to fulfil the Darkness' imperative by expanding the Dead Universe's hold into the living realm.

Nemesis may seem to hold sway over both his troops and the Darkness, but nothing could be further from the truth. The powerful Galvatron sees the Darkness as his rightful inheritance. And then, there is the fear. The fear that the Darkness has more in common with the Matrix than Nemesis is comfortable with. He feels he has earned this power, and isn't willing to see it follow its natural path. It is for this reason he must eliminate Optimus Prime. And it is for this reason he fears to face his successor.
