Thunder Warriors

The Thunder Warriors, also sometimes referred to in ancient records as the Thunder Legion and the Thunder Regiments, and known in High Gothic as the Legio Cataegis, were the 20 regiments or legions of genetically-engineered, superhuman warriors of Terra created by the design of the Emperor of Mankind through alchemical augmentation, somatic gene-sculpting and muscle-grafting techniques. Their purpose was to unite the homeworld of Humanity beneath the Emperor’s rule during the Unification Wars on Terra in the late 29th and 30th Millenniums. They were the first gene-enhanced warriors created by the Emperor and served as the precursors to the present-day Space Marines.
