Nimrod is a fictional character appearing in American comic books published by Marvel Comics. The character first appeared in The 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 biblical figure described in Genesis as a "mighty hunter". Source: Wikipedia (en)
