In 2005, I self-published four issues of Ninja Wolf along with some other sweet minicomics. (They're all still available for a buck apiece, so if you're interested, send me an email.)
Anyway, this illustration is NOT featured in any of the Ninja Wolf issues. It was done on an oversized art board just for fun, and once I started drawing it, I knew that "Ninja Wolf in Space" had to be the title (and plot) of the first Ninja Wolf movie. So think of this as a teaser for such a film, coming your way no later than 2026.
