Limelights real name is Lemuel Lighter. He was mad because when he was in a play with three celebrities a long time ago, they all became famous and he didn't. He thought that by kidnapping them he would become famous and broadcast it to the world so everyone would know who he was. The ninjas defeat him and his workers in the end and rescue the hostages that he kidnapped.
He used a machine and was using lights to nearly blind the ninjas but Owen gave them sunglasses so they could see and defeat him.
