The advanced power armor Mk II, often simply called Enclave power armor and nicknamed Black Devil armor by Brotherhood paladins is a power armor model used exclusively by the Enclave military forces, developed after the Great War to rival that of the Brotherhood of Steel. It is composed entirely of lightweight composites rather than the usual combination of metal and composite plates. Its design is substantially different from the earlier model using the same designation, but using a different helmet, and lighter materials.
