Shenzi, Banzai and Ed

This trio of hysterical hyenas are Scar's personal lackeys, and first appeared in The Lion King.

Shenzi
Shenzi is the female of the trio. She appears as the dominant one, seeming to be the most intelligent of the hyenas. She is constantly insulting the two males and resents the bumbling ones, although signs of friendship are shown. Her full name is Shenzi Marie Predatora Veldetta Jackalina Hyena.Her name means "savage", "pagan", "uncouth", or "barbarous". In the movie, she is voiced by Whoopi Goldberg and in Kingdom Hearts II, Tress McNeille.

Banzai
Banzai is the slyest of the group. Constantly hungry and moaning for food, he scuttles round the place for food. His name means 'skulk' or 'lurk'. In the movie and Kingdom Hearts II, he is voiced by Cheech Marin.

Ed
Ed appears as the least intelligent of the group. He is always smiling and laughs uncontrollably at anything. He never speaks at all, except for a minor part where he sings in Scar's Be Prepared. He is always the butt of jokes within the trio. He is voiced (if it can be called that) by Jim Cummings in the movie and the game.

Kingdom Hearts II
In the game, the trio are desperate for food and try and eat Sora, Donald and Goofy. They fail, but then try and eat Timon and Pumbaa. Sora and co. save the two friends by defeating the hyenas in a boss battle.

Later on in the game, the trio of hyenas are fought again for information on the source of Scar's ghosts. They know nothing of the ghosts, and taunt Simba about them. They are not seen again after that.

Trivia

 * Of all villains in the Kingdom Hearts history, Shenzi, Banzai, and Ed get the closest to killing Sora once and for all. The only reason they don't is because Banzai decides they should go see what Scar wants after he roars.
