Frame Arms Girl Greifen Barracuda is presented as a striking hybrid of armored mecha and bishoujo styling. The main armor is colored Hexa Blue, closely matching the Dual Spiral Crusher Set and Bulkarm Alpha, while joints and the Excannon are finished in gunmetal for contrast and upgrade-friendly customization. The kit features a fully detachable beret, a clear red helmet, and modified hair parts designed to fit beneath the helmet. It includes interchangeable hands in multiple poses, poseable fingers, and deployable sub-arm claws that open and close. It comes with Weapon Unit43 Excannon with a turret and torpedo system, and is designed for easy assembly with pre-printed face parts and 3mm joints.

Greifen Barracuda is the underwater combat specialist of the Frame Arms Girl line. Originally a Frame Arms mech created by Tomotake Kinoshita, she was reimagined as a bishoujo hero by Kinoshita for the Frame Arms Girl project. In the stories and kit lore, she thrives in aquatic theatres, wielding the Excannon and other weapon systems adapted to her light, agile frame. Her design emphasizes precision and adaptability, with a power suit that can rearrange into different armaments, allowing for fast bursts of speed or heavy suppressive fire. The pre-printed face parts capture her keen focus and wary charm—Looking Forward, Looking Right, and Winking—while the modular hair and helmet options let fans customize her pilot’s look. As a kit, Greifen integrates with parts from M.S.G and other Frame Arms products, encouraging cross-kit customization.
