Yangyang is a free 4-Star Aero character in Wuthering Waves who is unlocked right from the start of the main story. Players would be forgiven for thinking that, being a free 4-Star, she falls into the same category as Chixia, a sub-par character only meant to be played to get through the early parts of the story. No, instead, Yangyang is one of the most useful units in the game, specializing in crowd control and providing energy to her teammates.
