This coming month, a new add-on well thats what I think - named Skull Booster will be released - But before that let's take a look at the 14th HGBF Model kit "Cross Bone Gundam Maoh which appeared later in the series.
The XM-X9999 Crossbone Gundam Maoh (クロスボーンガンダム魔王 Kurosubōn Gandamu Maō?) is a mobile suit from the anime series, Gundam Build Fighters, and is a variant of the XM-X1 Crossbone Gundam X-1. The Gunpla is built and primary piloted by Mao Yasaka.
Reference: Gundam Wikia
One thing I really loved about the HGBF Model Line was their fancy box art - here we see X-Bone Maoh showing us a handful of it's chest cannon.
Upon completion, let's review what we have: first we have of course the X-Bone Maoh kit which was of course small but not as small as F91. Colour scheme was a little dull and boring but comparing to X-Bone original scheme I think with a little enhancing this one is better. Then we have a pair of peace sign hands - Maoh Yasaka's Master signature stance and some Triggering Hands. Then We have a large amount of Beam Blades, a pirate gun and a couple of daggers.
Up Front - Just like I stated before the color scheme was a little dull although the the particle light recharge scheme that were compsoed of stickers was somehow cool. And btw, that scheme has an available marker so might want to change that with those.
At Left Side - See, the Bone Backpack doesn;'t seem to be detachable so the Bone Booster that will be released is somehow questionable and a little different from what this kit already have.
Back - And Emphasizing on the X-Bone Back Pack that is yes the same as the original Crossbone but with the Bluish Particle Charge scheme.
Right Side - and have you noticed the Gun size on her side skirt? it's enormous right? haha but cool~
One of the coolest things you get in this kit are these Peace Signs which I beleive Maoh Yasaka's Massters Signature psoe which he inherited. Reminds me of Nobell though....
Bone Blades - which are yes can be change according to your hearts desire, can be a sword, a jur or even a spear.
Skull Chest - what most customizers want fromt his kit. Even me, this is one of the things that made me like this kit more. And would you even believe that up until now, I don't have Gundam X Maoh - and prefered tog et this one first because of it's skull chest.
Up close, the Skull opens its mouth and with just a little playful iamgination, imagine it shoots a large plavsky beam.
Under it's foot, are dagger slots that I have no idea what for. Do real pirates put these kind of stuff?
Then it has those cool daggers that looks like the daggers of Asuma in Naruto.
And who say's it can't spar with The O? it can also hold up to four beam sabers, 2 in the back and 2 in the hands.
Let's not forget this enormously big Pirate's Gun. It's Unique though since crossbones are the only one who has this type of Gun....
...Just don't think of real pirates, becuase if you do - you'll realize aren't those guns reloaded manually with gun powders?
Then It's Pirate Sword. One thing I really don't like about crossbone is the proportionality of it's weapons - this weapon seems too big for crossbone too.
Well what the heck - looks cool anyway.
And as a finalization - the pirate gun and sword can be combined together to form this odd looking machine gun rifle thing.
To sum everything up - The kit was never half bad, it doesn't lack any articulation and has bunch load of weapons that I'm sure you will find cool. Again, the scheme seems dull and needs a little polishing, the Skull Chest gimmick is still cool.
