An ancient Inhuman who led a group known as The Mayapan. This was a fellowship of Inhumans who posed as Mayan deities some 1000 years ago. These individuals began as citizens of the ancient Mayan Empire who had wondered off to a secluded section of the countryside. They came across a spring that was connected to a subterranean cache of Terrigen Crystals. They drank from the spring, exposing themselves to the Terrigen. The Terrigen-infused waters proved fatally poisonous for most of these individuals, but for a small handful of them it triggered Terrigenesis. Ixchel led this group and assumed the role of the Jaguar Goddess. She possessed magical abilities as well as enhanced strength and durability. The Mayapan ultimately returned home and used their newfound powers to take over the Mayan Empire, demanding that they be worshiped as gods and that a series of pyramids be constructed for them. The Mayan people eventually rebelled against these Inhuman overlords and somehow managed to defeat and destroy the Mayapan.
Ixchel, the last surviving member of these Inhumans, fled into an astral realm along with the disembodied life essences of her fellow Mayapan. She remained there in stasis for over a thousand years until she was awoken by a fissure cracked into the astral realm, accidentally created by the super-beings, She-Hulk and A-Bomb. Released, Ixchel manifested a giant ziggurat in the middle of the Canadian Rockies. She drained the life-force from She-Hulk, Lyra, and A-Bomb, using the energies to reincarnate her fellow Mayapan. The Red Hulk and Alpha Flight investigated the creation of this Mayan Pyramid and engaged the Mayapan in a tremendous battle. The Red Hulk was ultimately victorious and was able to restore She-Hulk and the others, forcing the Mayapan to again flee to the astral realm. This was the last that the Mayapan have been seen from and it is presumed that they continue to be imprisoned on an astral plane.
