Cyberpunk-style robot arm warrior、shining armor with a silver and blue metallic body、mechanical arm with the left arm that can be transformed into a huge weapon、with a red optical sensor glowing coldly。The background is a dark city neon city、reflecting asphalt wet in the rain。CG rendering taken from a low angle while standing all over。
