Nuwa

Nu Wa was a playable character in Dynasty Warriors 3. Not much is known about her, and why she was put only in that particular game, but in Chinese Mythology, she was the sister and wife of Fu Xi, and the first empress of China, and also said to secretly be a Serpent Goddess. She weilds a rapier and small shield, the latter of which is similar to Huang Gai's. She is unlocked by clearing the Musou modes of all female characters (not including Zhu Rong and Diao Chan as they didn't get musou modes until DW3:XL.) Like Fu Xi, she is only available for play in Free Mode.

In Warriors Orochi 2 She appears only because the Demon Lord, Orochi has been resurrected. She rushes to the aid of the kingdom of Wei to ensure that the Serpent King is once again defeated. She seems to have some previous connection to the Orochi.

At the same time she wishes to test and observe Cao Cao as she is worried that he could be as much a threat as Orochi if he falls down that path.
