Create a highly realistic visual depiction of an Obsidian Guard in action within a futuristic dieselpunk setting. The Obsidian Guard is shown in full motion, engaging in combat with powerful, advanced weapons and heavy armor that blends sleek futuristic design with rugged dieselpunk aesthetics. The armor is black with intricate metallic detailing, and the Guard's weaponry features a mix of mechanical and energy-based technology. The scene is set in a gritty, industrial environment, with the Obsidian Guard moving through smoke, debris, and explosions, showcasing their formidable combat prowess. The image should emphasize the dark, intense, and powerful nature of the Obsidian Guard as they dominate the battlefield.
