An LBX model is composed of three core components, the Core Skeleton, its Armor Frames, and the Core Parts. Each player can equip a variety of armor frame types to create their own "Customized Set", and random weaponry that determines its maximum performance.
The 'Core Skeleton' (コアスケレトン Koa Sukereton) is the anatomy figure made of Nanotechnology-based metal and high-resinated plastics. To protect it from sophisticated external damage, they are covered in a temporary armor default set called Cover Pads before purchase as sold separetly with the Armor Frames. The hollow space on the chest is the 'Core Box' (コアボックス Koa Bokkusu) where the key components (memory, CPU, battery, motor and extra-parts) to power it for movement.
Due to the aforementioned amount of high technology used in its development, an LBX is not affordable for the budget figures of a child. Even so, it is evident that there are plenty of ways that children get a hold of these state-of-the-art pieces of technology. It is speculated that perhaps society has advanced to a point where such technology has become somewhat cheaper than in the past.
The Core Skeleton is covered in a variety of parts called 'Armor Frames' (アーマーフレーム Aamaa Fureimu). A full frame set is composed of 5 parts for the head, torso, arms and legs. The frame parts are organized to their corresponding set of frame catalogues below and ranged in different grades. ( = Normal Grade, = High Grade, = Master Grade)
- Fighter-type Knight Frames (ナイトフレーム)
- Masculine-type Brawler Frames (ブロウラーフレーム)
- Feminine-type Strider Frames (ストライダーフレーム)
- Anthropomorphic Wild Frames (ワイルトフレーム)
- Tank-treaded Panzer Frames (パンツァーフレーム)
- Over 3,000 parts introduced since Danball Senki BOOST.
- Over 7,000 parts introduced since Danball Senki W (PSP).
- In the games, leveling up/increasing an armor frame's AC will deplete the Maintenance Gauge a bit after battle.
- The Preset Parts in W replace the extra weapons skills in Danball Senki BOOST, thus they are found randomly by 2 methods:
- Like the extra skills, the number of parts preset in an armor frame are determined by grade (HG = 1 part, MG = 2 parts)
- Not found in all shops within the game, they can be randomly obtained from enemy drops and Capsule Toys.
