Do you prefer Zero era Joanna or classic Agent Dark?
Keeping in mind that originally in the N64 game, Jo was supposed to have red hair, but the limited pallete and hardware of the system wouldn't allow it, so they went with brown. The XBLA remake obviously kept the brown hair as a 'legacy', if you will.
I was always a huge fan of the n64/xbla games and her commanding, yet beautiful look, and didn't take to well to the red hair.
Then I played Zero, and read the books and comic series, and fell in love, so to speak, with the younger redhead. In my opinion, her best look is with her red hair while suited up in the full Carrington Institute blue/black combat gear.
What do you think? Also, post fan art, I guess.
