–Excerpt from Nicholas's dossier
With the help of technological expert Grant Collier, he makes use of sophisticated 3D imaging technology (in whose initial development, and in the programming of whose control computer, he is believed to have assisted) that can quickly synthesize realistic latex masks based on photographs of an individual.
