Afterward, writer Howard Mackie injected more political and espionage elements into the series, a trend that culminated in the team's secession from government sponsorship. Multiple Man and Strong Guy appear again at the same time. Despite Forge managing to fix Strong Guy's problems, he does not rejoin the team. The popularity of X-Factor continued to dwindle and Mystique and Sabretooth, two popular X-Men villains, failed to draw in more readers.
