Hazbin Hotel Spin-off: Iron Man

Set four years before the opening of the Hazbin Hotel.

Vector, the Cyber Demon Overlord and proud member of the four Vees, is at the height of his power. His city of Cyberstan expands and grows stronger by the day, as does his own power. With allies like The Vees and the Fallen Archangel, Ramiel, Vector pushes through Hell to raise his power and expand his empire. The Cyber Demon has no plans of slowing down and as his strength grows, another coalition of Overlords is gathering strength for a fight against the four Vees. A fight that will force Vector to remember his life on Earth and force him to choose the man he'll be in Hell.

Important: Read 'Hazbin Hotel: The Judge' first as this is a prequel to that story so I'd suggest you read that first.
