 Simonson, who had been writing the team comic "The Avengers", had gotten approval for Reed and Sue to join that team after Engelhart had written them out of "Fantastic Four".Yet by "The Avengers" #300, where they were scheduled to join the team, Simonson was told the characters were returning to "Fantastic Four".This led to Simonson quitting "The Avengers" after that issue.
