Epic Shonen Crossover Poster

A hyper-detailed cinematic anime crossover poster featuring 4 legendary shonen-inspired heroes charging forward in a single epic battle composition under a dramatic apocalyptic sky. The scene is wide, symmetrical, and explosively energetic, with a glowing break in the storm clouds at the top center sending intense golden sun rays downward across the characters. From left to right: a blond ninja-inspired teenage hero in an orange-and-black outfit with a forehead protector, crouched in an attack stance and forming a glowing spinning energy orb in one hand, surrounded by orange chakra flames and several floating black spheres behind him; a muscular black-haired martial artist in an orange gi at left-center, twisting mid-strike while charging a bright blue energy sphere in his hand, wrapped in crackling blue aura and electric arcs; a lean pirate-inspired young man at right-center wearing a straw hat, sleeveless red vest, blue shorts, and sandals, lunging forward with a fierce grin, one arm extended, with white steam-like energy curling around his body; a dark-haired swordsman at far right in a flowing black-and-red checkered haori, drawing or swinging a katana with a sweeping arc of fiery red-orange energy around him. The background is a chaotic fantasy battlefield of shattered rock, sparks, lightning, embers, molten light, and swirling elemental effects, with orange fire dominating the left and right edges, cool blue energy concentrated around the martial artist, and white vapor around the pirate hero. Use extreme contrast, ultra-saturated colors, sharp inked anime linework, painterly textures, dynamic foreshortening, intense motion blur in the effects, and premium poster-quality rendering. Add a massive title across the bottom foreground reading [headline text] in oversized distressed brush lettering, bright yellow-gold with thick black shadows and rough torn edges, partially overlapping the characters and debris. Make it feel like a blockbuster key art poster for [franchise theme], with thunderous energy, heroic rivalry, and unstoppable momentum.
