Unicron let out a roar that could be heard clear across the Galaxy. Lilith had failed, and this god was the source of that failure. He figured he would have to do things himself. "You have failed me, creature!" Unicron said to Lilith. She was bathed in red light, and given excruciating pain as her atoms were one by one erased from existence. He would deal with Bob as soon as he got rid of his unworthy servant.

Optimus looked at the giant planet that was Unicron. "Unicron, leave this universe at once" He said, his voice tiny compared to the gods. Unicron ignored him, and continued erasing Lilith.
