The Rhino is the secondary, but true antagonist of Disney's James and the Giant Peach.
The Rhino is a giant black cloud that is shaped like a rhino with yellow eyes.
Powers & Abilities
The Rhino is made of clouds so it probably can't be harmed. It seems to have the ability to control the weather, because when it appears, a strong wind comes and a storm cloud appears, and when it arrives, lightning appears afterwards. It also uses fear as a weapon; the more a person fears it, the stronger it gets.
In fact, it represents James' fear.
In the movie, The Rhino came out of nowhere and gobbled up James' parents, forcing James to live with Aunt Spiker and Aunt Sponge. The two aunts used The Rhino to scare James. It is unknown whether The Rhino was once a real rhino when it killed James' parents, and if it is just a spirit haunting James (more likely the second one since Rhinos are herbivores and don't eat meat). When James and his insect friends finally reached New York, The Rhino appeared and tried to slow down their process. It was slowly coming towards the giant peach using the power of fear. When James mustered up the courage to say he's not afraid of The Rhino, it disappeared, but not before shooting a bolt of lightning at the giant peach.
In the book, The Rhino is a normal rhino that escaped from the London Zoo.
