Batman, clad in a gritty, high-tech Batsuit, unleashes a flurry of martial arts moves against Spider-Man, who wears a sleek, high-detailed Spidey suit, amidst a fantastical, ruined Gotham City metropolis at dusk, with intricate stone carvings, Gothic spires, and mystical, ethereal energy emanating from the environment. The two superheroes clash, with webs entangling Bat-equipment, in a stunning, high-octane, 8k resolution splash screen depicting the DC and Marvel universes in a gritty, photorealistic light, reminiscent of the styles of Simon Stalenhag, Loish, and Ash Thorp, blending contrasting, high-contrast colors with deep, rich tones, highlighted by Unreal Engine 5's cutting-edge, real-time rendering capabilities.
