Nimrod is a fictional character that appears in comic books published by Marvel Comics. The character first appeared in Uncanny X-Men #191 (March 1985), and was created by writer Chris Claremont and artist John Romita, Jr. Hailing from the “Days of Future Past” timeline, Nimrod is a powerful, virtually indestructible descendant of the robotic mutant-hunting Sentinels. His name is derived from the Nimrod described in Genesis 10:8-9 as “a mighty hunter before the Lord.”
Nimrod is the most advanced form of Sentinel robot. Nimrod can convert his outward appearance to resemble that of an ordinary human being. Nimrod can also reconstruct himself so as to make improvements in his robotic form and internal systems that will make him a more formidable opponent. Even when smashed to pieces, Nimrod can reintegrate the portions of his body to become whole again. Apparently Nimrod’s electronic consciousness can somehow exist independently of his physical body, at least temporarily. Physically Nimrod is categorized in the “Official Handbook of the Marvel Universe” as possessing “Class 100” strength because Nimrod could engage the Juggernaut in hand-to-hand combat.
Nimrod contains highly advanced computer systems as well as scanning devices that make it possible for him to determine whether a human being is a superhuman or not; if they are, he can determine the nature of their superhuman abilities. Like present day Sentinels, Nimrod can draw upon devices and systems within his robotic body in order to cope with or neutralize an opponent’s superhuman power once he has determined the nature of that power.
Nimrod is capable of projecting energy blasts, magnetic energy to levitate material, create force fields, and can teleport. Nimrod has a weakness for elemental attacks such as lightning or extreme cold.
