Dynamite Entertainment, who published the Red Sonja comic books at the time, collaborated with animation studio Shout! Factory to produce this motion comic, which takes the script of Gail Simone and the original art of Walter Geovani and Jenny Frison, then adds small bits of motion that can kind of, sort of be called a cartoon. It’s kind of like the way Grantray-Lawrence Animation did The Marvel Super Heroes in the 60s with a bit more tech.
If you’ve only seen the live-action Red Sonja, this is closer to the comic book version of the She-Devil with a Sword. Our heroine (Misty Lee, the magician wife of animator Paul Dini) comes back to a kingdom to pay back the blood debt to the king who freed her from the slave pit, but finds herself battling Annisia, a woman who she once considered her sister.
While the animation is rough and this wouldn’t be the story I’d introduce new readers to when it comes to Red Sonja, it’s nice to see this character getting any media mentions after decades of a rumored film.
You can watch this on Tubi.
