In each series, the "Revolution" issue represented a jump of six months after the previous issue's events. In most cases, "Revolution" also marked an attempt to send each title in a new creative direction, and to this end new creative teams were assigned to the titles. Many characters' costumes were redesigned, and a "Revolution" logo was printed along the right-hand side of each issue.
The excitement of the event was dampened by Marvel Comics' timing, as most of the series involved had launched with all or part of their new creative teams a month before the event, even though the "Revolution" logo was still printed on the May issues, and Uncanny X-Men did not join the "Revolution" event until its June 2000 issue. Furthermore, Claremont stated in later interviews that he had ghostwritten several issues of various X-Men titles before the event.
Furthermore, three of the titles involved in the event, (X-Man, X-Force, and Generation X), were rebranded to Counter-X. Writer Warren Ellis plotted the general direction for each of the Counter-X books, and co-wrote each title with Steven Grant on X-Man, Ian Edginton on X-Force, and Brian Wood on Generation X.
The "Revolution" event was poorly received by fans and critics, leading to Claremont leaving X-Men and Uncanny X-Men after nine months. The X-Men line of books were revamped again in July 2001 with Grant Morrison writing New X-Men, Joe Casey writing Uncanny X-Men, and Claremont writing the new title X-Treme X-Men.
