Morrigan Aensland is very vain, and lives for little more than the excitement of battle, although her endings in the games as well as various media show that Morrigan slowly takes up more of her responsibility seriously. She appears as a beautiful woman with long, light green hair, and bat-like wings on her back and the sides of her head. She is a versatile fighter, having a wide range of physical and magical attacks.
Although Demitri would seem to fill the spot, it is often suggested and implied that Morrigan is the main character of the Darkstalkers series, due to her importance in the overall story as well as her many appearances outside of her own game series. She may even be considered the protagonist or something of an anti-hero, since despite her demonic appearance and nature, she is not evil. She is a woman with a lovely figure. Her measurements are: 86-56-83 (B-W-H).
Now, did you intend this to be end of game Alan Wake? If so, Morrigan poses no threat to him unless he allows it. He literally has the power of a writer writing a story. The battle would go however he damn well wants it to.
