Jax's Metal Arms are large, cybernetic enhancements that replace his forearms and hands, designed with a high-detail, realistic art style. The arms feature a combination of polished metallic surfaces with visible mechanical components, including pistons, hydraulic lines, and reinforced plating. The color scheme is primarily metallic silver with black accents, showcasing a battle-worn texture with scratches and dents that hint at intense combat use. The design is both functional and intimidating, with the hands ending in powerful, articulated fingers capable of crushing opponents.
