@professorrespect: Didn't Batman once say something about Plastic Man surviving in pieces on the ocean floor for a great length of time?
I believe the quote goes something like this:
"Plastic Man survived for 3,000 years as little more than crumbs scattered across the Atlantic. If that doesn't give you an idea of the level of power he hides behind that smile of his, then you're brain-dead."
-Batman to Atom
Did this happen? I haven't read the story in question, so it's just hearsay for me.
Also, if this is War of Jewels Morgoth, then he's a lot weaker there. Fingolfin was able to challenge him, and even granting that he's one of the greatest Elven warriors, that's still well below Morgoth at his mightiest.
