I only discovered this cartoon in 2021 during the Covid lockdown, and it was a very pleasant surprise for several reasons: it was presented as one long serial broken up into 16 chapters (at least for season 1), it features often gorgeous painted backdrops and solid animation, and had some pulpy adult themes. Pretty well every episode involves Flash, Dale and Zarkov visiting some new kingdom or meeting a new species, usually with a too-literal name like "Arboria" or "Frigia" . There's Hawkmen, Lionmen, Arborians (tree dwellers), giants, dinosaurs, etc. Ming is indeed merciless, Princess Aura a femme fatale, while all the local queens fall in love with Flash as Dale frets in the background. Well deserving of a DVD re-release.
