Space pirates, and a mantle full of skulls
The Crossbone Gundam is what happens when the Universal Century gets a pirate story. The XM-X1 is small, fast and covered in skull motifs, and the Full Cloth version wraps it in a heavy layered mantle that works as both armour and a statement. From the Mobile Suit Crossbone Gundam manga, and one of the most distinctive silhouettes Bandai has put into Master Grade.
The detail that sells it: the skulls on the mantle come off and mount on the hands, so the suit can punch with them.
Build difficulty
A full-sized Master Grade with a big accessory count. The assembly itself is snap-fit with no glue required, but there is a lot of it, and the mantle sections plus the weapon load make this a longer sitting than a standard MG. Best suited to a builder who has finished a Master Grade or two. Not a first MG.
Technical highlights
The weapon list is the headline and it is genuinely long: the Muramasa blaster, the Zanbuster, the peacock smasher beam crossbow, a screw whip, the brand marker beam shield, beam sabres, heat daggers and a buster gun. The Full Cloth mantle layers over the core X-1 frame, and the whole thing can be displayed with the mantle off to show the much leaner suit underneath. Stickers and marking sheets are included.
What makes this kit special
-
Detachable mantle skulls that become fists: lift the skulls off the Full Cloth mantle and mount them on the hands as boxing gloves.
-
Full Cloth mantle over a core suit: display it cloaked, or strip the mantle and show the bare Crossbone X-1 underneath.
-
Peacock smasher: the multi-barrel beam crossbow, and easily the most unusual weapon in the box.
-
Muramasa blaster and Zanbuster: two large signature weapons, both with their own presence on a shelf.
-
Screw whip and heat daggers: a genuinely deep accessory set for one kit.
-
Beam effect parts: included for the Zanbuster and the brand marker beam shield.

Compatible accessories
No display base is included with the kit. With the mantle on and the larger weapons deployed, a stand makes the difference between a static pose and a proper action display. Pair it with the Bandai Action Base 4, the standard 1/100 display stand.

What to watch for
This kit has a mixed reputation and it is worth knowing what that reputation is. The complaints that circulate are that the mantle makes it stiff to pose and that it is prone to toppling. Against that, a builder who actually finished it reported the build as completely fine and said it was nowhere near the brick they had been led to expect. So the picture is genuinely split rather than settled, and I would not present the criticism as established fact.
What is not in dispute is the physics. The Full Cloth mantle is a lot of plastic hanging off the shoulders and back, and the larger weapons add more. Expect to think about balance, and expect a stand to help.
Builder tips: build the core X-1 first and have a look at it before you commit the mantle, because the bare suit is a genuinely good display in its own right. Fit the mantle sections dry before you seat them fully. If you are posing it with the Muramasa blaster out, put it on a stand rather than fighting the balance on the shelf.
Build notes
No glue and no paint required. Nippers, a hobby knife, sanding sticks and tweezers for the smaller skull parts. Budget four to six hours across a couple of sessions given the mantle and the weapon count. Recommended age 15 and over.
