The witch who has been supporting Kro-Tan successfully resurrects the true King of Mongo, unveiling herself as his Queen and regaining her youthful appearance. They imprison Kro-Tan and subsequently trap the Defenders using a powerful spell. However, the King turns against his Queen. In captivity, Kro-Tan informs his allies about the King’s resurgence, prompting the Phantom to boost his powers and liberate the Defenders. Their confrontation with the King is cut short when Kshin’s earlier discovery of mystical creatures leads to a melodious chant that causes the King's defeat once more. Ming is restored and furiously takes his son away for retribution.
