The Zodiac(Team)

The Original Avengers of Earth's Ancient Past
Created by The Kree Empire to win an ancient inter-galactic war, The Zodiac were the result of experiments by Kree Scientist and Yakkub of Attilian to try to create Eternals (Ancient Super Powered Humans) from an even more distant past of The Kree. Trapping wild humans on Earth, the Kree used their blood to transform the humans in hopes that they would become the army they needed. The Zodiac strangely seem to be counterparts to the current Avengers, though this might have been intentional as Zodiac translates to "The Avengers" in Kree. Though in Greek it means circle of little animals, but not all the symbols are animals.

Greek Zodiakos "Circle of Little Animals"

Many of these created Eternals still exist as Corrupted Eternals, who keep their life force going by consuming the bodies of others or taking hosts to maintain them. Hydra/Alveaus took Grant Ward as it's host, before it's destruction. The current host of Merrikan is Apocalypse(Evan Rockford). Cytorrak's host is the Juggernaut, Cain Marko.
