|~ Bori Khan's most famous quote.|
A Rouran warlord, Khan sought to annihilate China and kill the emperor in revenge for the death of his father. To achieve this end, he allied himself with a powerful witch, Xian Lang, who serves as the film's secondary antagonist. Khan takes the place of Shan Yu, the main antagonist of the animated film.
Bori Khan is established from the beginning to be an agile warlord, managing to kill, alongside his men, dozens of Chinese soldiers in rapid succession. Like Shan Yu, Khan is ruthless and bloodthirsty, stopping at nothing to ensure China and its people are conquered.
The similarities between the two stop there, however. Unlike Khan, Shan Yu never had any real reason or motivation for conquering China beyond lust for power. Khan, on the other hand, seeks to destroy the empire out of revenge for the murder of his father, implied to have been at the hands of China's emperor, though the exact circumstances are never explained. Additionally, Khan is shown to have a deep, open resentment to women and their roles in society, exemplified best by his horrid treatment of Xian Lang and his initial dismissal of Mulan as a "child". Shan Yu, by contrast, never showed any signs of sexism, but instead, showed surprise when Mulan revealed herself as the soldier who annihilated his army.
Böri Khan was the warrior leader of the Rourans. He entered the Palace and attacked the occupants along with his men and Xian Lang, who were attacking the warriors and killed them, but he was in a war fighting to face them back with his violent battle.
As Mulan was battling against him he was caught in an avalanche and the Rourans were defeated, but he escaped from the avalanche and she would against Xian Lang, after that he was shot dead. After Xian Lang's death, she would battle against Böri Khan. Mulan cut the rope and he fell down into the palace and he was killed by an arrow.
- Bori Khan is the first and so far only antagonist to replace another in a Disney Remake of a previous one.
- On top of being given a more fleshed out and sympathetic backstory than Shan Yu, Bori Khan also had more screen time than him and did more killings than his equivalent did in the original animated Mulan.
