Robert Kirkman (The Walking Dead) had the most volumes on the chart of the Top 20 Author Graphic Novels in the book channel for the full year 2017 with six, according to information provided to ICv2 by NPD BookScan.  Brian K. Vaughan was second, with five volumes (Saga and Paper Girls).

Combined with the first volume of Monstress, that gave Image 12 volumes of the Top 20, a dominant performance in the category.

Congressman John Lewis had the third most volumes in the Top 20, with three products featuring his memoir (March).

Six of the Top 20 were essentially one-offs, self-contained stories that had nothing to do with any other titles on the list or off.

We define our "author" graphic novel category as featuring creator-owned or -controlled properties.

This chart of the Top 20 Superhero Graphic Novels from NPD BookScan for the full year 2017 is one manifestation of a new deal between ICv2 and NPD (see "ICv2 to Publish NPD BookScan Graphic Novel Bestseller Charts").

NPD BookScan collects weekly point-of-sale data on print books from over 16,000 locations including e-tailers, chains, mass merchandisers, independent bookstores, and more.  NPD BookScan covers approximately 85% of the U.S. trade print book market.  The ranks on this chart are based on piece sales. Some publishers classify titles that are primarily text, or art books, as graphic novels; we've removed those titles from the ranking above.
