A vibrant fantasy illustration of a white unicorn with a rainbow mane and glowing horn facing off against a fire-breathing black dragon in a mystical forest.

Generate me a depiction of a mystical unicorn, white in colour, has a colourful rainbow mane swishing from side-to-side like trees in the wind. On her bottom, a pink hairy tail sways furiously and her hooved legs kicking angrily. Her magenta, glowing horn shines and charges at an infuriated black dragon with glowing red eyes flickering like lights. His giant wings with blood-red membranes and 3 digits flutter while floating in the air. His gaping jaws breath steaming-hot fire, damaging the unicorn slightly. He has fierce claws, sharp spikes and a swishing tail. On the right, behind the dragon, a fiery landscape swirls above like a flaming-hot storm churning in the sky. On the left, near the unicorn, a mystical landscape filled with lush foliage, glowing electric-blue bulb-plants, wild grasses and red butterfly-like leaves appear. The brutal battleground's ground is filled with more lush foliage, glowing blue rocks and more. See more
