I have a feeling that they are similar in power. Lord of Nightmare (Slayers) against Lucifer Morningstar (DC/parts of Vertigo). Who do you think wins? If there is a winner...
Battles with omnipotent beings involved (Lord of Nightmares in this case) aren't allowed here.
I love Lucifer Morningstar, but the Lord of Nightmares wins horribly.
Omnipotent battles are not allow
@Sonata can lock this?
It's been a long road...
