During the late 80’s, sales of The Fantastic Four had been struggling, so Steve Englehart decided to make radical changes. He felt the title had become stale with the normal makeup of Reed, Sue, Ben, and Johnny, so in issue #308 Reed and Sue retired and were replaced with the Thing’s new girlfriend, Sharon Ventura, and Johnny Storm’s former love, Crystal. The changes increased readership through issue #321. At this point, Marvel made decisions about another Englehart comic, West Coast Avengers, that he disagreed with, and in protest he changed his byline to S.F.X. Englehart (S.F.X. is the abbreviation for Simple Sound Effects). In issue #326, Englehart was told to bring Reed and Sue back and undo the other changes he had made. This caused Englehart to take his name entirely off the book. He used the pseudonym John Harkness, which he had created years before for work he didn’t want to be associated with. According to Englehart, the run from #326 through his last issue, #332, was “one of the most painful stretches of [his] career.” Writer-artist Walt Simonson took over as writer with #334 (December 1989), and three issues later began pencilling and inking as well. With brief inking exceptions, two fill-in issues, and a three-issue stint drawn by Arthur Adams, Simonson remained in all three positions through #354 (July 1991).
