A striking, futuristic logo for a YouTube channel called 'Marvel DC Hero Zone.' Incorporate elements from both Marvel and DC universes, with bold, metallic typography split into two: Marvel's half in red and blue tones, and DC's half in black and blue. Use subtle superhero symbols or silhouettes (like a shield, lightning bolt, or cape) within the background, with a cosmic or comic-book style. The design should have glowing highlights, clean lines, and a modern, professional look, capturing the essence of both superhero worlds.
