A 4:5 portrait of a terrifying cyberpunk nano-tech berserker in mid-transformation. The central figure is a muscular, gender-ambiguous person with dark olive skin, their body partially consumed by a swarm of metallic nanobots. Their left arm has fully transformed into a massive, shape-shifting weapon. The character's face shows a mix of rage and ecstasy, with one normal eye and one glowing mechanical eye. They wear tattered combat fatigues, revealing more nanobot-infested skin. The background depicts a ruined laboratory with sparking equipment. Foreground elements include swirling nanobot tendrils. Lighting: harsh, contrasting light from multiple broken light sources. Style: hyper-detailed digital illustration with photorealistic textures. Camera settings: f/2.2, 1/320s, ISO 500, 35mm lens. Photoshop effects: microscopic detail enhancements, dynamic motion blur, and atmospheric haze. No unrealistic muscle bulges, no symmetrical nanobot patterns, no static posing.
