A colossal, iridescent phoenix with feathered wings made of swirling cosmic dust, clashing with a massive, obsidian golem whose body is cracked with glowing, unstable energy, erupting from the cracked crimson desert floor of a distant, terraformed Mars in the far future, illuminated by the binary sunset and a supernova explosion in the background, rendered in the 'DemonFlux + tarot coffee' style with bold, inky linework, a palette of deep amethysts, fiery oranges, and electric blues, and layered, ethereal textures.
