Jack Kirby/Joe Sinnot line style animated. You can also see elements of John Buscema's run with Stan Lee in The Silver Surfer's first solo series. (1968?). I remember this show as a kid, unfortunately I believe it only lasted 1 season. I haven't investigated it yet, Im wondering if it had something to do with Marvel's Bankruptcy issues around that time.
Ha, the Kree soldiers look like Captain Marvel's original design,
