Wonder Woman and Black Panther

Both Civil War and Batman v Superman introduce characters who have been long overdue for their turns on the big screen.
Batman v Superman has the first appearance of Wonder Woman, a 5,000-year-old princess of the Amazons. She doesn’t want to get involved in the big fight at first, but somehow she is convinced that it will be for the better.
In the same way, T’Challa is basically forced to involve himself in the fight, after his father is killed and Bucky is framed for the murder.

Another similarity between these two characters is that we still don’t know how their powers work. Of course, comics readers might know a bit more! T’Challa fights Bucky (who is, basically, superhuman) without his suit. And does Wonder Woman fly or does she leap?
There are actually quite a few unknowns about both of these characters. I didn’t expect to find out a great deal about them, anyway, because both of these movies are just teases (from a specific point of view).
