Fighting Duke with Mai can be hard. However, if you keep using her combos, such as Super
Deadly Ninja Bees and Windwill Waster and do not allow Duke to power up any of his most
devastating attacks, you will defeat him. Note: This may require a lot of practice;
use practice mode until you are skilled with Mai's combos. Defeating Duke in story mode
