Unlike the other mobile fighters in the Gundam Fight, the Bolt Gundam is powered by a powerful "Victor Engine", which makes it the strongest mobile fighter in terms of raw strength. It complements its power with exceptionally strong armor that can shrug off most ordinary attacks. This combination of strength and durability suits Argo's fighting style, which relies heavily on enduring enemy blows to put him in a position to deliver overwhelmingly powerful counterattacks. Argo frequently uses the Bolt Gundam's durability to get face-to-face with his foes, allowing him to use his Gundam's superior strength to lift, crush, and throw his opponent.
The primary weapon of the Bolt Gundam is the Graviton Hammer, a flail-type weapon that consists of a dense spherical hammer that is manipulated via a beam chain. The weapon can be used in a variety of methods for both offense and defense and increases the Bolt Gundam's reach in melee combat, allowing it to utilize its physical strength at the maximum possible range. When not in use, the hammer portion is stored in the Gundam's left shoulder, while two beam emitter "hilts" are stored in recharge racks in the gauntlet-like armor on its forearms.
As with most melee-focused mobile fighters, the Bolt Gundam lacks a ranged weapon outside of the standard vulcan guns on its head.
In the events leading up to the Shinjuku arc, the Bolt Gundam is infected with DG Cells. Although it doesn't have any visible changes in the TV series, the manga adaptation Super-Class! Mobile Fighter G Gundam: Shinjuku/Undefeated of the East!, shows the Bolt Gundam with a new, mutated design that incorporates parts resembling the JDG-009X Death Army. The infected Bolt Gundam has noticeably heavier armor with its upper body greatly increased in size. It has enhanced strength, but is never seen using the Graviton Hammer.
