I think Jean Grey is on of the most complicated fictional characters in comic books. I've lost count of the number of times she "died" and returned. She has the power of telepathy and telekinesis. She is also in love with Cyclops but attracted to Wolverine. It is a highly dramatic love triangle in the comic books and used well in the 1990's animated series and in the live-action movie trilogy. And it was not explored in X-men: Evolution since Logan was an adult while Cyclops and Jean were teenagers. She has also gone by various code names like Marvel Girl and Phoenix. For a time she was possessed (actually replaced) by an alien entity called Phoenix and was almost god-like. I have found two version of Jean in Mugen. Here is the chart:
|Phoenix by Comedy HaHa & Hsieh||5||6||7||http://www.sendspace.com/file/enb8dx|
|Dark Phoenix by Emanuele on GundamRX79 / ComedyHaha's Sprites||9||8||9||http://members.xoom.alice.it/tbaacm/w_i_p.htm|
I enjoyed playing with both characters. The thing is Dark Phoenix has a lot of over-the-top moves. They are a lot like the other Phoenix version but way more powerful.
