Superhero and author graphic novels divide neatly into winners and losers, while manga are a bit more complicated.

Two superhero properties, Infinity Gauntlet and Infinity War, take the first and third spots on the May graphic novel chart.

Infinity Gauntlet dominated the May graphic novel chart, with the second highest sales this year.

This week's home entertainment offerings include a rare ambitious misfire from Disney, Ana Duvernay's A Wrinkle in Time, a disparate bunch of crime films including the Bruce Willis Death Wish and the indie black comedy Thoroughbreds, plus the latest season of South Park and the complete run of the Hulu adult animated superhero comedy series The Awesomes.

New titles dominate the Superhero chart, but the Manga and Author lists are all over the map.

While superhero titles are the lowest selling category in the book channel, there’s an interesting difference this month between the charts.

These are estimates of the sales on graphic novels by Diamond U.S. to comic specialty stores during April 2018.

Eight out of the top 20 are superhero, showing that the genre continues to be popular whether it's coming from America or Japan.

The drop-off from the top two slots is sharper.

For the second month in a row, Black Panther graphic novels dominate the March superheroes chart, taking up seven of the 20 slots.
