Shenzi is one of the many hyenas that once obeyed the malicious Scar. She is also a part of a trio of hyenas with Banzai and Ed.
As an adolescent, Shenzi along with her friends surround a helpless baboon named Rafiki who arrived in the Pride Lands. King Ahadi comes to the rescue just in time, with his sons Mufasa and Taka close behind him where Ahadi chides the hyenas, telling them that they had already eaten. However one of the hyenas, Shenzi, tries to object, but is silenced by Ahadi and he chides at them for disrespecting the rules of the kingdom and orders them to leave Five Stones. After their failed hunt, the hyenas skulked at a distance from Pride Rock, complaining about Ahadi and his constant supervision. Banzai and Shenzi exchanged complaints about the king and advocated the ushering in of a new era, amusing that with Mufasa dead, they would be able to rule the Pride Lands. Later, Shenzi advises Taka to make himself look good by making Mufasa look bad. Taka has decided to incite a selfish buffalo named Boma to fight Mufasa. But the plan didn't turn out so well, and Taka's eye was wounded by the buffalo herd in the process, and hences the name "Scar" from then on. Next they are preparing to boil Zazu until Mufasa passes by, and scares the hyenas away.
