S1·E50 The Prince Dethroned (5)

The witch who's aided Kro-Tan from the start manages to revive the original King of Mongo, and is revealed to be his Queen while having her youth restored. They lock Kro-Tan away and later do the same with the Defenders via a magical transportation. The King then disposes of his Queen. In the cell, Kro-Tan reveals that the King has returned, and the Phantom, after enhancing his strength, frees the Defenders.

The showdown with the King is interrupted by the arrival of the creatures Kshin discovered earlier, whose singing brings about his downfall once again. Ming is restored, and angrily takes his son off for punishment.
