Recent teaser images for 'X-Men: Regenesis' confirm that X-Factor #230 sees former team member Havok join the book's roster, something David has been working towards for some time.
"[Editorial] said that Havok was in play and would I be interested in bringing him into X-Factor," David told Newsarama. "The timing of it was ideal, it fit perfectly with other developments in the series."
David also commented on Rictor regaining the use of his mutant powers, a development that occurred outside of X-Factor in the current miniseries Avengers: The Children's Crusade.
"It will have considerable impact, yes, particularly on Rictor and Shatterstar's relationship," David confirmed. "Shatterstar is going to wonder whether Rictor hooked up with him simply because, between being abandoned by Rahne and losing his powers, Rictor felt vulnerable.
"Except Rahne returned and now his powers are back and Shatterstar, who's more or less been the dominant one in the relationship, is going to start feeling uncertain and even vulnerable."
The writer promised X-Factor will start to become more integrated with the rest of the Marvel Universe in the wake of the current X-Men: Schism event.
X-Factor #225 will be published on September 21
