- The first of the Aqueos, created by the Great Old Ones using Sh'g'th tissue, a formless substance used to create unholy life, circa 18,000 BC, after the sinking of Atlantis and Deviant Lemuria.
- elderly vampire Aqueos (vampirized Atlanteans, Lemurians, and other undersea people), who eventually gain a more piscine form, sprouting tails, patagial rowth between limbs, and eventually bloat, rendering verbal comunication and motion difficult, seemingly impossible, and causing them to depend on others for feeding.
They, and their eldritch energy radiation power-boost to Aqueos warriors/drones, were documented in an obscure footnote about the old vamp-races, in the darkest of the dark books, the Necronomicon, believed to be one of many imperfect copies of the ancient writings etched on the walls of R'llyeh.
The knowledge of the Old Ones was passed down, from an Aqueos to its Aqueos spawn.
In the midst of the war betweeen the X-Men and the Vampire Nation, the Shallow Peace between Atlantis and the Aqueos was broken after Namor led a party in Black Smokers' Trench to retrieve Dracula's head, and fought the Aqueos, led by Namor's grandfather Thakorr.
In order to annihilate the Aqueos by using a separation charm, Namor led a party (including Abira and the Tridents) into R'llyeh. Namor and Abira entered the Tomb where they prepared the charm in front of the ancient Aqueos, unable to move, as Namor was going to sacrifice himself, as the spell required all of the blood of a king. The tentative was interrupted by Thakorr.
The ancients witnessed their fight. Having discovered the Necronomicon information about the Old Ones' eldritch energy radiation power-boost to the Aqueos drones/warriors, Young X-Man Loa (Alani Ryan) and Logomancer arrived in the battle, and cancelled out the power-boost using a simple static spell. Abira and Namor finally defeated Thakorr, and used him to power the charm. It was mostly succeful, though some Aqueos survived it. The ancient Aqueos were seemingly all destroyed.
Powers and Abilities
Eldritch Energy Radiation Power-Boost: The ancient Aqueos radiated eldritch energy, which gave a power-boost to near Aqueos' warriors/drones.
- R'llyeh, the Aqueos city, was known as the "Seventh World of the Ancients", according to Zartra in the Lemurian Witch-Scrolls. It is unclear if that name is a reference to the ancient Aqueos, or to another group, possibly the ancient "things", the beings from the stars (Great Old Ones) who created the Aqueos.
