Shenzi, Benzai, and Ed

Shenzi, Banzai, and Ed are among the sidekicks that were imprisoned on the Isle of the Lost. They are the parents of the Spotted Hyenas given to the children of the villains. They appear in the book The Isle of the Lost.

Before The Isle of the Lost
During the events of The Lion King, Shenzi, Banzai and Ed were loyal henchmen to Simba's evil uncle, Scar. They first appear in the Elephant Graveyard when they find Simba, Nala, and Zazu and try to attack them until Simba's father (Mufasa) comes to save them and attack the three Hyenas. Soon, Banzai comes up with the idea to kill Mufasa when he said this to Scar, "Yeah what are we supposed to do, kill Mufasa", which Scar agrees. To prepare Mufasa and Simba's death, the hyenas attack a giant pack of Wildebeest to chase off Simba. After Mufasa is killed by Scar, he tells the hyenas to attack Simba (since he survived the wildebeest attack). Shenzi, Banzai and Ed failed to kill Simba since he went through a dense thorn thicket they couldn’t follow him through, which the hyenas gave him a warning, "If you ever come back, we'll kill ya", after this, they later lied to Scar that Simba was dead (confident that he would die out in that desert anyway) and the Hyenas along with Scar take over Pride Rock. Years Later, Shenzi, Banzai and Ed were starving to death, since the lioness won't go hunting, Scar tells them to eat Zazu instead, by they disagree. After Simba's return, the hyenas get frightened of Scar since they lied to him about Simba being dead. During the battle, they're defeated by Pumbaa and when they were on their way to help Scar, they refuse since Scar tells Simba that, "It's the hyenas, who are the real enemy, it was their fault, it was their idea". After Scar's defeat, Shenzi, Banzai, and Ed and along with the surviving nine hyenas, attack and kill Scar.
