Affiche Crossover Épique d'Anime Shonen

A cinematic anime crossover poster featuring four shonen-inspired heroes charging forward in a single battle composition under an apocalyptic sky. Wide, symmetrical, dynamic composition with a glowing break in storm clouds at top center casting golden sun rays downward. From left to right: a blond ninja teenage hero in orange and black with a forehead protector, crouched in an attack stance forming a spinning energy orb, surrounded by orange chakra flames and floating black spheres; a muscular black-haired martial artist in an orange gi, twisting mid-strike while charging a bright blue energy sphere wrapped in crackling blue electricity; a lean pirate young man in a straw hat, sleeveless red vest, blue shorts, lunging forward with a fierce grin, one arm extended, surrounded by curling white steam; a dark-haired swordsman in a black-and-red checkered haori swinging a katana with a sweeping arc of fiery red-orange energy. The setting is a shattered rock fantasy battlefield filled with embers, sparks, lightning, and swirling elemental effects. Style: sharp inked anime linework, painterly textures, dynamic foreshortening, saturated colors, extreme contrast, blockbuster theatrical key art. Across the bottom foreground, massive distressed brush lettering reads "[SHONEN LEGENDS]" in bright yellow-gold with heavy black drop shadows and rough torn edges, partially overlapping debris, themed around [legendary shonen anime crossover].
