Keeping tabs on all of Marvel's superheros is pretty challenging work -- the company has been publishing comics for 75 years. Over 2,500 characters have lived in its pages, spanning more than 3,000 individual issues over more than 440 series. How did I know all that? Well, I stole the stats from Ultimate 75th, a student-made website that pilfer's Marvel's own database to celebrate 75 years of comics. Students at the Hétic school in France built the site in just four days using the REST API used on Marvel's official site. This allowed the group to pull comic and character data directly from the publisher's database. The result is impressive, but it isn't perfect.
