A low-angle maritime shot captures two colossal primordial entities: Cthulhu and Hastur, clashing their massives fists in a tempestuous sea. Cthulhu, a towering winged leviathan with writhing tentacle tendrils, scaly hide, and glowing emerald eyes, looms leftward with its immense forelimb drawn back for a strike. Hastur, a massive amorphous shape cloaked in tattered robes with skeletal protrusions and piercing yellow eyes, looms rightward making contact with Cthulhu. The backdrop features a volatile ocean with towering waves, black storm clouds, lightning flashes, and a dark cloudy night sky; rain streaks through the air and mist rises from crashing water surfaces. Mature anime-style rendering presents glossy high-finish surfaces, subtle skin gradients, warm highlights, controlled color harmony, smooth brushwork, and soft, sensual lighting under stormy conditions.
