One plot that comic publishing companies use in order to get fanboys to spend all of their money is to publish superhero team-ups. A team-up is when various superheroes from various comics all come together in one book. This requires patrons to buy an extra comic and it introduces them to new characters. Most comic nerds won’t be content with just that comic, but they will then be compelled to buy all the comics featuring the other superhero. This helps boost comic sales and prevents fanboys and their families from ever becoming homeowners.
