No matter how curious Sunny was about what would happen if he and Nephis woke up one day and decided to battle to the death, he had to admit that he was badly matched against her dark copy here in the Underworld.
If he was wielding all his powers… he honestly did not know what the outcome would be. Sunny was an immensely powerful being himself, but his true strength lay elsewhere. His Shadows were immensely powerful, and he commanded a deathless legion of shades. He was also a master of sorcery. Of course, if his Domain were to be included, then Neph's had to be included as well.
Which meant that the question wasn't really who would win in a fight, him or Nephis. The question was who would win in a war — Sunny and his legion or Nephis and all of humanity.
