Deathclaws are a large, agile and strong species of mutant Jackson's Chameleon[1] created through genetic engineering, with the addition of DNA of various other species.[2] However, due to mutation, they have lost their color-changing ability. The deathclaws were originally created before the Great War by the United States Military in order to replace humans during high risk, close combat, and search-and-destroy missions.[2] Later on, when the Master was building his army, the Master had sought to improve upon their design to make them more lethal; however, before he could use his experiments to his own ends, the Master's experimental deathclaws escaped in the Fialer Earth to propagate through the continent. Deathclaws are also exported from Fialer Earth to be used in gladiatorial combat.
