Texcatlipoca and Mictlantecuhtli took turns in commanding or possessing the demon monkey. After Barbossa was shot, Texcatlipoca ordered Jack to live on the far side of Isla de Muerta, away from the cursed treasure. The dead island had no food and little water, but Jack didn't need it. He was under the protection of the "heathen gods," as his former master so kindly put it, so Jack needed neither food nor water. After three years of nearly wasting away on Isla de Muerta, Jack received a visit from Mictlantecuhtli. The Lord of the Underworld ordered Jack to swim back to the unholy cove and take one of the medallions from the chest. He possessed the back of the monkey's mind to make sure nothing went wrong.

The monkey swam dutifully to the other side of the island and entered the cove. He made his way to the cave and entered it silently, barely breathing. The Aztec God possessing him had not been there in a long time, and it thrilled him. Jack gazed at the piles of treasure that his master's crew had plundered over the span of ten years. However, he was not interested in any of it, except for the stone chest that was on top of a mountain of golden coins, jewelry, and statues. At the bottom of the mountain was the corpse of Captain Barbossa. Amazingly, he did not look dead or rotten; on the contrary, he looked like he was merely lying there resting. Curiously, the monkey went over to the captain, just to make sure that he wasn't sleeping. He was surely dead. The monkey ignored his former master for the moment, and began hopping up the mountain. Almost instantly, he landed on the cursed chest of Cortés. He chirped softly and touched the gold with his tiny paws.

The glimmering medallions were cold, freezing almost. On the other side of the chest and through Jack's eyes, Mictlantecuhtli saw two coins with dried blood on them. He commanded the monkey telepathically to seize both of them. Jack crawled over to coins and stared at them for a moment. Then he snatched them up like lightning, jumped off the chest, and scampered under the moonlight.

He turned into a skeleton.

Both the Aztec God and the monkey screamed triumphantly.

Then, from behind him, Captain Barbossa said, "Fancy meetin' ye here, Jack."

The monkey turned around and saw his captain standing in the moonlight, a skeleton also. "Thank'ee, me faithful li'l monkey. Who knew th' curse could do sucha thing as this," continued the captain with a menacing grin, looking down at himself. He stepped out of the light for a moment and looked at his bloodstained shirt. "An' I thought he'd kill'd me." Barbossa stepped back into the moonlight and looked around the cave evilly. "Now… where be Sparrow?"

It was then that Mictlantecuhtli left the monkey's mind, leaving Jack to shrug stupidly. The monkey felt a presence at his left side, and looking up he saw the physical form of the Lord of the Underworld. He was a terrible sight to behold. He was a skeleton, similar to what Barbossa looked like, but his bones were paler and every few inches or so there were small droplets of blood clinging to his ghastly frame. He was clothed in an emerald green toga bordered with black trim. He wore a golden crown on his bare head. Possibly the most shocking feature about the God were his disturbing red eyes that were staring at Barbossa with more malignancy than the evil pirate himself could muster. Barbossa, in turn, was gazing at the God with a look of pure terror on his face.

"You will have your revenge on Jack Sparrow soon enough, Barbossa," Mictlantecuhtli hissed. His voice was like venom dropping from the fangs of a serpent, and both Jack and Barbossa flinched at the sound of it. "But until then, I have a little task for you." It was hard to tell whether or not he was smiling, as he had no skin to contort.

"I shall do wote'er ye ask me to, me Lord," Barbossa said, his voice full of fright and barely above a whisper.

Mictlantecuhtli's eyes became pools of bright fire and he rasped, "I know you will. Now, come. We must make haste to my kingdom. We must go to the Underworld."
