The primary duty of the majordomo is to report on activity in the Pride Lands to the reigning monarch. They are especially vital to informing the monarch of emergencies, such as wildfires or stampedes. In addition, the majordomo is often tasked with caretaking the princes or princesses of the kingdom, as was a frequent duty of Zazu.
The majordomo is expected to retain utmost loyalty to the monarch, even at the expense of his life. Zazu demonstrates such a loyalty when he offers to give himself as tribute in place of Kion, the son of the reigning monarch Simba.
