Cyborg monster from the murky depths, featuring elaborate mechanical details and eerie emerald eyes that pierce through the darkness, combining the menace of a half-fish, half-machine entity. Its skin, slick and glistening, reveals hints of metal beneath as it emerges from a misty, wetland backdrop. Rendered in Unreal Engine 4, it showcases a hyper-realistic, 3D model with dramatic, cinematic lighting that highlights its sinister presence.
