are an enormously large, agile, and strong species of genetically engineered reptiles. They are substantially larger than a human, and have large and dangerous claws. It is claimed that they were originally derived from mixed animal stock DNA (mostly Jackson's Chameleons) before the Great War
to replace humans during close-combat search-and-destroy missions and later refined by the Master
, using genetic manipulation, but the accounts of their origins vary. Although they do not have vocal chords, the deathclaws seem to be able mimic human speech much the same as a parrot does, although normal deathclaws aren't intelligent enough to be capable of real speech.
