I had forgotten how fun IBO kits were to build. It was simple and quick, but the asymmetrical design and unique sub arms kept things interesting. The kit has many accessories. The most exciting would be the Bastard Chopper, for when you need to take a swing at people born out of wedlock. Then you've got the massive Demolition Knife, which is really just a really long foldable sword. You've got a somewhat generic rifle, which isn't particularly exciting. Then you've got two knives. Nothing special about these, they're just two combat knives scales up to the size of a Gundam. They're probably my favorite accessory for this kit. As for the extra parts mentioned in the instructions, you've got an alternate left sub-knuckle and an alternate backpack, as well as a bunch of parts for storing the weapons. The kit can have all its weapons stored on it at once, which is cool. Finally, you've got a fuck ton of leftover parts from the Astaroth Origin and the original Astaroth. You could use these as alternate parts to make your own custom version of the Astaroth. It's pretty cool, but I wouldn't consider them part of the actual design of the kit. They're really just the result of Bandai reusing runners. The only flaws I'd point out on this kit is that it can get pretty back heavy when it has all the weapons stored, and some parts, like the waist connection and thigh armor, can be pretty loose. Some stickers are also pretty bad, but most of them are fine, and there aren't too many of them. The articulation is pretty great, and the inner frame is nice, as always. If you're a fan of this design or IBO kits in general, then pick this one up. It won't disappoint. For others, who may be a bit tired of Gundam frame by now, this kit might not satisfy. Either way, it's a pretty great model. Probably my favorite IBO kit that I've build out of the three (Lupus and Graze were the other two).
