The villain does something super illegal or evil but the hero that always goes after him doesn't come
He decides to wait for him but he still doesn't show
He looks for the hero and it's been a week and he starts to realize nobody is looking for him . Not his family, fans , friends nobody but him
He finds out everybody has been cirticizeing and making fun of him for letting the villain go which was just him.
He later finds him in a warehouse, dead hanging himself
(What happens next is up to the author but it would but I would've put )
He grabs a rope and ties it and sets it right beside the hero then says " well friend If you go away. I will join you ,and We will have more fun in the afterlife . Don't worry friend for I will always be there for you " and then jumps and hangs himself
