First the basics: It's a realistic story, in a "Batman realism" sense. I'm thinking Tim Burton-Batman realism. (with the Joker dying in the end of the movie, and ignoring all the comics books that said he survived.) So anyway, in the story, this world is created in the image of Heaven and all that. Or Heaven created in the image of this world, if you prefer. But there is also another world created in the image of Hell. The two worlds are hid from each other, so no one can know about them. If you know your Lovecraft, you know about the Ancient Ones putting a Veil over mankind to hide themselves, as the human brain is too weak to see behind the Veil. If the Veil is liften, humans would go crazy, or something like that. Aaaaanyway, we have one Guardian protecting the city. She is made from a the genetically best parents from both worlds. (one from each world, of course.) She has lived alone her entire life to protect the city. In short, her face is more feral than humans, she has yellow eyes and sharp teeth. Not unlike a wolf, in many ways, but no so much that she can't pass for human if she puts on sunglasses and a hat. There's also a Hunter, working very much like the Guardian. The difference is the Hunter travels wherever she's needed, all over the country. Even all over the planet, in theory. The one I need help with is a third character. The Guardian and Hunter both go on the hunt for a great evil lurking in the city, and the hunt takes them to a woman called Nyki. She is from the other world, and while she looks human "enough", she is more a reptile (no tail, though) than human. She also have yellow eyes and sharp teeth like the Guardian, but her hands and feet are reptile-like, and her skin can change color like a chameleon. It turns out the great evil the Guardian and Hunter are chasing came from Nyki's world, and she chased it all the way over to our world to try and stop it. But she knows she doesn't belong here, and she knows she can't go back. But that's pretty much all I know about her. I could use some advice on how to make her "better". The Guardian use close combat most of the time, and the Hunter is excellent with firearms. There's also a human cop involved, but she's more of a thinker-type. If you know DC Universe or Smallville, she'll evolve and become a Watchtower-type. That leaves Nyki. I want her different from the other three, but all four will eventually start a team together. Nyki's ability to alter her skin makes her near-invisible in some situations if she stands still, so I'm thinking she can be a spy, assassin or something like that. Any ideas?
