Jump and shoot.
Wonder Woman actually has a really good post-minigun game, which is a problem because it's your only safe ender off of b13. She can check you with b1 and make you guess if you sit still, and if you jump up, forward or back you eat b2. Backdash is the best option as she has to make a read to punish it. WoWo gets a good 41-45% for punishing it and even if she doesn't, you're only backing yourself into the corner. She can walk in pretty freely and punish or parry your zoning attempts so it's difficult to keep her out for very long. You can also end with MB minigun which is a better option if you're willing to spend a meter, but you won't always have that.
