9. Shenzi, Banzai & Ed The Lion King
Who Are They?: A trio of hyenas who act as Scars lieutenants and help him to murder Mufasa.
Why Are They So Horrible?: Although they ally with Scar mainly to improve their lot in life, theyre still pretty damn evil. When Simba is a cub, they try to murder him twice (and try to kill Nala and Zazu at the same time), and theyre directly responsible for the wildebeest stampede that Scar lures Mufasa to in order to kill him. They also fight on Scars side along with all of the other hyenas during the battle of Pride Rock and presumably injure a few lionesses in the process. Their only saving grace is that they kill Scar and eat his corpse, though that was an act of revenge after he tried to blame them for Mufasas death rather than serving a greater good.
What Happens To Them?: Their last appearance in The Lion King is leading a pack of hyenas in ripping Scar to shreds, and the sequel briefly mentions that the hyenas abandoned their home in the elephant graveyard at some point after Simba became king, meaning that they survived and had the foresight to run like Hell rather than mess with Simba again.
