The Rhino is the secondary antagonist of James and the Giant Peach.
The Rhino is the cause of death of 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 friends finally reached New York, the Rhino appeared and tried to slow down their progress. 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 ultimately dissolved, but not before shooting a bolt of lightning at the giant peach.
