So, if it comes to pass, I'm thinking of my fourth character. Of course I have a list of characters to choose from, so once again I'm conducting a poll.
1. Gabriel 'Sylar' Gray; of Heroes fame. He would of course be on Niflheim's side. Those who watch Heroes know that this man is infamous for taking abilities; and they will also know that he has the ability of empathetic mimicry (the ability to absorb the abilities of others simply by being around them, and forming some sort of empathetic connection to them.)
Sylar could no doubt be considered a threat to Asgard because of his 'hunger' for power. Unfortunately he'd be a threat to Niflheim for that exact same reason.
2. Walter Kovaks aka Rorschach; of Watchmen fame. I would be pulling him from the graphic novel; right, with that out of the way; Rorschach would be on Asgard's site, purely for the fact that he believes that there is good and evil in this world, and evil must be punished. He believes that good and evil are separate and should never intermingle; he's a misanthrope who actually wants to see innocence prevail.
He has no supernatural abilities, but he's extremely resourceful; having at one point killed a man with a toilet.
He would be the character who would interrogate members of Niflheim for information using some extremely harsh methods.
3. Mark Hopkins; another OC of mine. He comes from the same world as Flauros and Raziel, but has no connection to them. In his world, Mark was an extremist right winged fundamentalist Christian. He would however be on Niflheim's side, and for a good reason. Mark is notorious for being a grand hypocrite. In his world, all humans were supposed to have abilities, but that didn't happen because of the fall.
However, a select number (12 to be exact) were born with a certain ability that awakens only when a traumatic, or significant event happens to them. Mark's ability is one: to see aura's and determine who has power(s) two: the ability to absorb powers.
How does this make him a hypocrite? Mark believes that anyone who has a supernatural ability is either a witch, a warlock, or a demon. He's taken at least three abilities, and uses them himself.
Personality wise, Mark will piss everyone off I imagine. He'll insist that Lucifer is Satan, will imply that Metatron is actually a demon (because Metatron is mentioned only in the writings sanctioned by Satan.) He'll debate by tossing out Bible verses (that usually have little to do with the debate at hand.) and will constantly ignore the facts presented to him.
4. Michael Dillion aka IX; another OC for Niflheim. Has the ability of vocal persuasion, and vocal mimicry (the ability to alter his voice to perfectly match/sound like someone else.) He was the lead vocalist of a death/gore metal band.
He's a Christian turned atheist, and sees himself as a self appointed 'angel of Judgment'.
