Create a 3D model of an action figure named "Skull Crusher." Design him with exaggerated musculature in a sturdy, multi-jointed body. He has a fierce, oversized smiling face with sharp teeth and large eyes, wearing a torn leather jacket with vibrant, graffiti-like patterns. His pants are tattered cargo style, complemented by combat boots with skull embellishments. Use a vibrant, chaotic color palette reflecting 80s and 90s pop surrealism.
