Megalodon and Leviathan in a Dark Underwater Battle

16:9 Cinematic Dark Realistic Underwater Footage. In the pitch-black depths of the ocean, a massive, terrifying 20-meter-long megalodon, its sharp teeth bared, is ferociously tearing at a matte black, heavily armored sci-fi vehicle (its appearance is reminiscent of two BvS10 all-terrain vehicles docked at their rear). Not far away, a massive, ferocious Leviathan whale is ambushing the megalodon with a deadly attack. Electric blue sparks erupt from the truck's armor. Underwater bubbles, blood mist, the dark, murky depths, extremely detailed skin textures, dynamic lighting, 8K resolution. --ar 16:9
