Revenants are UAC Military operatives that have been methodically transformed into demonic combatants through cybernetic augmentation and repeated Lazarus Wave exposure. The transformation begins by attaching a Multiple Launch Rocket Battery (MLRB) onto each shoulder of the patient, coupled to an Argent-charged neural biochip implanted at the base of the cerebral cortex. The MLRB allows the Revenant to both attack its target with multiple conventional rockets, and also to fire mobility boosters located under each MLRB.

During initial delevopment of the Revenant program, a curious side effect of Lazarus Wave exposure was discovered. The Argent Energy held within the plasmatic isotopes of the Lazarus Wave mutates ossein proteins, resulting in rapid skeletal growth. The expansion of the bone matter results in avulsion of the skin and connective tissue. The flesh is literally torn from the bones. As the skeleton continues to grow, the exposed internal organs begins to decompose. After several weeks of intense pain for the patient, the skeletal growth stops- resulting in a 3 meter beast comprised primarily of bone. The height varies depending on patient's original physiology. Despite this bizarre biological structure, the Revenant appears to bear no ill effects.
