Mortamor

Mortamor is the true antagonist and final boss of the Super Famicom and Nintendo DS videogame Dragon Quest VI. He is the master of the Four Dread Fiends: Murdaw, Jamirus, Gracos and '''Dhuran. ''' He sent them to seal four strategic locations in the Dream World that he considered a threat to his plans, he also terrorized the Real World inhabitants with monsters because he desired to conquer both worlds.

Despite having multiple forms, they often resemble red demon-like creatures. His first form is an old man that uses yellow spheres to attack and cast spells. His second form is a burly red demon with massive defense and strength. Finally, he will cast away that last body and break apart a dimensional barrier to come out strongest form: A giant demon-like head with a pair of disembodied hands that, judging by its entrance, could have his body anchored in another dimension.

Mortamor is the master of the Dread Realm, a dimension set apart from the Dream and the Real worlds, there are some unfortunate souls that ended there one way or another and are suffering by his schemes and tortured by its demon minions. The sages Benjamin and Isaac who represent a threat to him, are among these people. Peggy Sue cannot transform into Pegasus while in this world.
