Mulan

Past Timeline
During the times of the war in the Aisha continent, Mulan's father was very sick so she enlisted in the army in his place. She dressed as a boy and hid her real identity in order for her father to not be sent to war. Despite the bullying and the physical differences, Mulan trained very hard to be an excellent swordsman and eventually she did become one.

She met Lu Bu in the war against Xiang Yu and helped him in the battlefield. Eventually her identity as a female was discovered and she was immediately kicked out of the army and her status of general was removed.

Season 2
She witnessed an army of Lu Bu and Guan Yu going into crisis and danger so Mulan accepted the power of destruction in order to awaken and save them. Lu Bu was thankful and decided to bring Mulan back to his army.

She's still an enemy of Xiang Yu.
