AI Prompt for Dark Anime Villains Crossover Poster - Generative Art and Royalty-Free Key Art

"A dark, cinematic anime villain poster in an ultra-detailed gothic horror style, arranged as a single dramatic collage against a ruined infernal city. Use a wide landscape composition with a black, crimson, and electric violet palette, heavy smoke, ash, embers, magical lightning, and chaotic painterly energy. Feature 4 major villain figures. In the center foreground, a massive obese pirate emperor with a huge grin, wild black beard, open red captain coat, bare scarred chest and belly, layered necklaces, belt, and multiple pistols tucked at his waist, holding 2 flintlock pistols outward in a triumphant pose. Behind him at upper center, a tall pink muscular demon-like humanoid with a smooth head and a single curled head tentacle, standing with arms slightly spread, glowing with purple aura and lightning. On the left foreground, a pale long-haired Japanese swordsman in loose light robes, head bowed slightly, surrounded by a giant coiled serpent rising behind him with open mouth; add the vertical Japanese text "大蛇丸" near this figure and the vertical text "魔人ブウ" near the upper-center figure. On the right, a tall elegant demon lord in layered dark kimono-like robes, long flowing hair, calm sinister posture, framed by 8 smaller dark red moons plus 1 large full red moon above the head, for a total of 9 moons; add the vertical Japanese text "黒ひげ" near the pirate and "鬼舞辻無惨" near the right figure. The background should be a hellish apocalypse of shattered towers, burning ruins, and shadowy architecture fading into smoke. At the bottom, place huge aggressive brush-painted title text reading {argument name="headline text" default="RISE OF VILLAINS"} in blood red with magenta highlights, rough torn edges, and glowing texture. Make the whole image feel like an epic crossover key art poster, extremely high contrast, ominous, supernatural, and menacing."
