Mufasa is a majestic lion. He is the husband of Sarabi and the father of Simba. In the opening of the first film, the animals of Mufasa's kingdom arrive at Pride Rock to greet and honor the birth of his newborn son and their next king, Simba.

Mufasa's brother, Scar, is enraged that he has lost his place as Mufasa's immediate successor upon the birth of his nephew, and Mufasa scolds him for not being present at Simba's presentation.

Mufasa teaches his son the delicate balance of affecting all living things and takes him to a trip through the Pride Lands, but warns him not to go outside the lands' limits, especially the elephant graveyard. Simba disobeys his father and, along with his best friend Nala, is nearly killed by Scar's three hyena henchmen, but they are saved by Mufasa in the last minute. Mufasa is furious with Simba for deliberately disobeying him and putting Nala in danger. Simba tells him he was just trying to be brave like him. Mufasa tells Simba he's only brave when he has to be and his was scared because he thought he might lose him. Afterward, he tells Simba about the Great Kings of the Past looking down from the stars in the sky. He tells Simba if he ever feels alone, they will be there to guide him, and so will he.

Out of jealousy, Scar formulates a plan to kill his older brother and nephew so that he could be king. Scar's plan is partially fulfilled when he kills Mufasa after Mufasa saves Simba from a wildebeest stampede initiated by the hyenas under Scar's signal.

After Simba is all grown up, Mufasa's spirit appears and reminds him that he is his son and the rightful king and must take his place in the Circle of Life.

In the sequel, The Lion King II: Simba's Pride, Mufasa's spirit is present at the birth of his granddaughter, Kiara.
