Zeta Gundam’s transformation relies on two key technologies: the Movable Frame and Gundarium alloy.
The frame itself can extend and slide. Lightweight, high-rigidity Gundarium armor panels attached to it are pulled inward, allowing the machine to change shape in about 0.5 seconds thanks to magnet coating.
Because the change is so fast, the suit is less vulnerable during transformation. Integrating the shield into the outer armor also increases overall rigidity.
