The advanced power armor Mk II,[Non-canon 1][1][2][3][4][5] often simply called Enclave power armor and nicknamed Black Devil armor by Brotherhood paladins[6][7] is a high-end model of power armor used exclusively by the Enclave Department of the Army and developed after the Great War and the destruction of the Enclave Oil Rig in 2241. It is composed entirely of lightweight composites rather than the usual combination of metal and composite plates found on the previous designation of advanced power armor, the MK I.[8]


The advanced power armor Mark II represents a significant upgrade over the older Mark I. It is composed entirely of lightweight ceramic composites, providing even more protection than the regular advanced power armor.[8] Unlike the Mark I, the Mark II features a large profile, and more effective, segmented armor plates to achieve a superior degree of protection, with the hump replaced with pauldrons that evoke old world power armor designs, such as the T-45. The helmet assembly retains the insectoid eyepiece arrangement of the Mark I helmet, but the overall shape has been changed to an even more insect-like appearance, with a reduced vertical profile.[9]

The suit was originally available in limited qualities. Following the destruction of the oil rig and the flight to the Capital Wasteland, the Enclave has designated the Mark II as its official service uniform and manufactured it en masse once it gained access to Raven Rock and Adams Air Force Base, eventually displacing the older, less protective Mark I suits entirely.[10]


The set consists of two pieces, the body armor, and helmet. Like all power armor, power armor training is required to equip it. It provides +1 Strength and -1 Agility. There is also a 5% increase to Radiation Resistance.





  1. The Lone Wanderer: "What do you make of the Enclave, Squire?"
    Arthur Maxson: "Y... You're asking me what I think of the Enclave? Well... The Brotherhood of Steel has actually faced the Enclave before. Back West. More than thirty years ago, according to our chronicles. Judging from those records, I'd say their soldiers are outfitted in Advanced Power Armor Mark II. It's... pretty strong. Better than our Power Armor. And some of their technology is amazing! Vertibirds! Plasma weapons that can turn a man to goo! Does... that help?"
    (Arthur Maxson's dialogue)
  2. The Lone Wanderer: "So... Any thoughts on the Enclave?"
    Bowditch: "They're sporting some pretty impressive Power Armor, I'll give them that. The Advanced Mark II. But that's all right. With a few modifications, our own armor will more than handle anything they throw at it."
    (Bowditch's dialogue)
  3. The Lone Wanderer: "Here's some Power Armor from the Enclave."
    Henry Casdin: "Well I'll be damned. The Advanced Power Armor Mark II. This is superb. Absolutely superb."
    (Casdin's dialogue)

  7. The Lone Wanderer: "So... Any thoughts on the Enclave?"
    Peabody: "So they have Plasma weapons! Bah! It's strong technology, I'll give you that, but limited in modability. I've already started removing the compensators on our laser weapons to cut through the Black Devil power armor of theirs. We'll drop them like any other meat, don't you worry."

  1. Fallout 3 Official Game Guide Game Of The Year Edition p. 130: "This is also known as Advanced Power Armor Mark 2. The Enclave sacrifice part of the Strength bonus, but there is less Agility penalty with this armor. It is also slightly more hard-wearing."
