The Deathclaw is a fictional reptilian species from the post-apocalyptic Fallout video game franchise. They were created by humans as biological weapons prior to the series' in-universe nuclear war. Escaping into the wild afterwards, they went on to thrive in the nuclear wasteland, becoming apex predators. Known as one of the Fallout series' most recognizable and iconic elements, Deathclaws were praised by critics for their design and the fear they induce in the player due to their immense power. As a result of their popularity, numerous mods were created for Fallout series games with the Deathclaw as a central theme, either to tame the creatures as a pet or use them in combat, concepts which were later added as an official feature.

The Chief and the Arbiter are captured during their separate missions on Delta Halo, or Installation 05, by a Gravemind, which resides in the bowels of the ancient Forerunner ringworld, where the Flood creature forges an alliance between the two foes in order to stop the activation of the ringworld — an event which would destroy all sentient life in the galaxy, and, therefore, starve the Flood to death.
