A dark, gritty illustration of Spider-Man and John Wick standing back to back in an urban alley at night. Spider-Man is wearing a sleek, tactical suit with elements of black leather and armor, his mask slightly cracked, revealing intense eyes. He stands confidently with his web-shooters visible, ready for action. John Wick, dressed in a black suit, stands calm and poised, holding a weapon in one hand, his other hand relaxed but ready. Both figures exude a grim determination, facing the criminal underworld. The scene is set in a shadowy, neon-lit city, with dark alleys and skyscrapers in the background, capturing a sense of vengeance, inner demons, and the line between justice and chaos.
