given a new uniform, designed by Kane and colorist Michelle Robinson, and greater abilities. An added plot feature was the introduction of sidekick Rick Jones. Jones and Marvel "shared molecules" allowing only one to exist in the real world at a time. Thomas stated that the intent of the change was to create a more science-fiction oriented update that was reminiscent of Fawcett Comics's original Captain Marvel, who similarly had an alter-ego that could not co-exist with the superhero. The change, however, was not successful, and the series was published only intermittently from 1969. It was initially canceled with issue #21 (August 1970), though the character appeared in the Kree-Skrull War storyline in Avengers #89 – 97 (June 1971 – March 1972), also written by Thomas. The Captain Marvel series recommenced with issue #22 (September 1972). Plotter and artist Jim Starlin decided to revamp the character with issue #25 (March 1973). Comics historian Les Daniels noted that "In a brief stint with Marvel, which included work on two characters [Captain Marvel and Adam Warlock] that had previously never quite made their mark, Starlin managed to build a considerable cult following." A spin-off series, Ms. Marvel, was launched in 1977, but sales remained modest, and the series was published on only a bimonthly basis until it was ultimately canceled in 1979. The continued publication, however, kept the trademark current. This had the effect of requiring DC Comics, which in the meantime licensed the original Fawcett Captain Marvel for publication, to print its new comics under the trademark Shazam! Comics historian Don Markstein states, "Marvel didn't seem to quite know what to do with him—but they did put his comic out every other month through most of the 1970s, if only to maintain their trademark on his name." When Captain Marvel was cancelled with issue #62 (May 1979), there were five as-yet unpublished issues already complete or near-complete. The series Marvel Spotlight was revived for the express purpose of publishing them (specifically, in issues #1-4 and 8). Starlin wrote Mar-Vell's death in Marvel's first graphic novel, The Death of Captain Marvel (1982). Following the character's death, Marvel published several comics with new characters taking up the "Captain Marvel" moniker, thereby maintaining their trademark on the name. The character returned, although not in a living capacity, in storylines in Silver Surfer vol. 3 #63 (March 1992) and Captain Marvel vol. 5, #5 (March
