Merlock is a major antagonist in the Kingdom Hearts Unlimited Saga, first appearing in "The Keyblade Wars" playing half of the role of Luxu, Apprentice of Master Solego. He goes on to appear in "The Journey", "A Year of Misery", and "Return of the Keyblade", assisting Maleficent with her plans involving the Princesses of Heart by serving as one of the leading members of the Elite Dominion, while also secretly enacting his own schemes to fulfill the will of Chernabog in opposition to Darth Sidious' faction.
Merlock desires the powers of the Djinn lamps in order to harvest their magic and make himself more powerful than them to prolong his evil immortality. This is because he is actually one of a few surviving notable individuals from the Age of Legend, an ancient era that came after the Age of Chaos fell, but before the divisive catastrophe of the Keyblade War. As such, he has seen many vast empires rise and fall, partly through his own influence, and it is his research into the study of the twelve magic elements of the universe that helped Palpatine gain his needed knowledge of the past for his own evil ends.
Appearance and Abilities
Merlock is an anthropomorphic wolf. He possesses a green magic talisman that gives him magic powers, which include the ability to turn into (non anthropomorphic) animals, including a hawk, a beetle, a gryphon, a bear, and a mountain lion. When placed on a genie's magic lamp, the talisman grants Merlock an unlimited number of wishes to be granted, instead of the usual three.
At some point in the past, Merlock was the minor jinn Gene's master, and was granted immortality as his first wish. When he had possessed the lamp, some of the sorcerer's wishes that were unwillingly granted by the Genie included his own immortality, the destruction of Atlantis (which was caused partially by the combined efforts of both him, the Ethereal, and the Heart of Atlantis itself) and the eruption of Mount Vesuvius that wiped out Pompeii.
