Brock Lee is a supporting antagonist in Casper: A Spirited Beginning.
Brock Lee along with his friends, Leon, and Danny, Jennifer constantly bully Chris Carson, for his love of the supernatural. However Jennifer changed her tone later in the film. The boys almost got Chris in trouble, when the water balloon they tried to drop on him landed on the school principal by accident and got detention. He had another detention when Casper appeared and tried to stealth use a fire extinguisher on him and got the principal covered in it. This lead him and his friends to capture Chris and have him locked up in the Applegate Mansion unaware that a bomb was planted by Bill Case. After the bombing is thwarted, Jennifer told the boys that Chris almost died because of them. Rather than feel guilt for their actions, Brock and his friends thought it was cool. The boys eventually get their comeuppance in the end, when Chris had the Ghostly Trio scare them off by also giving them each a mega wedgie and have them hang on a tree as Brock and his friends scream in fear, pain and agony.
