I think that WW should appear skilled, and in that top tier of fantasy warriors, but I don't want to see too much obvious Eastern Martial Arts influence, even though it is of course going to be in there somewhere in the mix. I would say that her ability to fly also plays a part in how you present her in combat on the big screen. If she isn't going to fly then I say merge some conservative use of wire work and parkor. She should sort of be like Cap in TWS times ten, considering that she is many times stronger than Cap is, so the moves would not only be skillful and fluid looking but also pack concrete shattering power if any should make contact. I think she should have a style that has lots of throws and locks, but also be a dynamic one, where she can handle multiple attackers, so some good straight forward and not to flowery striking too. Something that is supposed to give the vibe of her having learned some kind of Combat Pankration or the like. Against normal human foes she should be able to subdue them without hesitation using some kind of joint or body lock as her go to move. I would like to see her use her environment as well. I don't see WW as being on the same exact level of invulnerability or strength as Superman, and as such, I could see her using her surroundings to her advantage a lot, like picking up debris to chuck at her equally powerful foes, or using one vehicle as a battering ram against another vehicle. If she has a weapon available and the situation calls for it, she should have that aspect integrated into her fighting, not just as a hand held weapon, but utilizing her strength she could also use them as a ranged attack tool by throwing say a sword or shield. I think that for a superhuman, we should see her level of concentration and skill come out as she fights, especially against opponents like Cheetah or Giganta or First Born who can match her in physicality. Perhaps, given the connection to Mythical heroes of Western Culture, perhaps her fighting can also have a bit of swash buckling flare as well?
