The [[New X-Men (2004 series)|New X-Men]] team decided to raid the headquarters of the [[Purifiers (Marvel Comics)|Purifiers]] in Washington, D.C., but were forced to retreat. [[Pixie (X-Men)|Pixie]] teleported them back to the mansion in a rush, but the entire team was scattered between D.C. and Westchester. Iceman, after recovering from his injuries, volunteered to go look for them and was given telepathic directions by [[Emma Frost]].<ref>''New X-Men'' #45</ref>

Iceman was successful in finding the New X-Men, most of them injured. On the way back, they found that the [[Sentinel Squad O*N*E|O*N*E* Sentinels]] guarding the [[Xavier Institute for Higher Learning|Xavier Institute]] had become infected by nano-Sentinels and attacked the school. Iceman and New X-Man [[X-23]] helped out in the battle with the O*N*E* Sentinels. With the help of [[Dust (comics)|Dust]] and X-23, the X-Men were able to survive this battle but the nano-Sentinel infected human escaped.<ref>''The Uncanny X-Men'' #493</ref>

Soon, Iceman participated in the final battle against the Marauders, the [[Acolytes (comics)|Acolytes]], and [[Predator X (Marvel Comics)|Predator X]]. He was one of the X-Men who came running in to fight Predator X after it swallowed [[Wolverine (character)|Wolverine]] whole. However, he also witnesses his mentor, Professor Xavier, "killed" by Bishop's bullet, which was not meant for him.<ref>''X-Men'' #207</ref>
