Gunpla Custom Build : HG 1/144 Gustav Karl: ZS Specification by @habafore

The HG 1/144 Gustav Karl: ZS Specification, masterfully customized by the Gunpla builder @habafore, stands as an exemplary model of unique modification and intricate detailing.

The Gustav Karl [Zs Specification] custom build has been completed as an all-out heavy firepower project. This time, the builder pushed the concept to its limit, creating a missile-laden assault machine that fully embraces overwhelming force.

The base Gustav Karl is already known for its mass and battlefield durability, but this version amplifies that identity. Missile launchers are mounted across the frame in dense clusters, reinforcing the philosophy that victory comes through sheer volume of fire.

The primary weapon is a heavy gatling gun, further strengthening its suppressive combat role. Rather than balancing the loadout with traditional melee options, the design deliberately rejects close-combat specialization. This machine exists to dominate from mid to long range.

Additional Armament

• Heavy Gatling (main weapon)
• Multiple missile pods across the body
• Buster Anchors mounted on the chest and rear

The addition of Buster Anchors provides a mechanical accent and utility element, but the core identity remains centered on ranged destruction.

While high-mobility builds have their appeal, this project intentionally celebrates heavy armor and concentrated firepower. Every element feels purposeful and aligned with the theme: load it up, reinforce it, and let it unleash everything at once.

The result is a Gustav Karl that embodies excess in the best possible way—dense, imposing, and unapologetically built around fire superiority.
