Design a high-energy, futuristic poster for an energy drink called 'CoCo'. The can should be sleek, metallic, and tropical-themed, with glowing neon accents in green and electric blue. Include splashes of coconut water and lightning effects to symbolize energy. The background should have an urban, cyberpunk night vibe with motion blur to create a sense of speed. Bold, modern typography should display the name 'CoCo' with a tagline like 'Pure Power. Natural Boost.' Use dramatic lighting and contrast for a powerful, eye-catching look.
