Marvel Comics.</ref>  During the [[Dark Avengers]]' arrival in San Francisco to enforce martial law and squelch the anti-mutant riots occurring in the city, Xavier appears (back in his wheelchair) in the company of Norman Osborn and publicly denounces Cyclops' actions and urges him to turn himself in. However, this Xavier was revealed to be [[Mystique (comics)|Mystique]] who Osborn found to impersonate Xavier in public.<ref name="Uncanny X-Men #513">''Uncanny X-Men'' #513.

However, as Emma frees him of the Void's influence, a minute sliver of the entity itself remains in her mind. Xavier quickly tells her to remain in her diamond armor state to prevent the Void from gaining access to her psi-powers. Professor X is later seen with Emma Frost where Beast is recuperating.<ref>''Dark Avengers/Uncanny X-Men: Exodus''. Marvel Comics.</ref>

After what happened at ''Utopia'', Xavier has come to live on the risen Asteroid M, rechristened Utopia, along with the rest of the X-Men, X-Club, and mutant refugees and is also allowed to join the Utopia lead council (Cyclops, Storm, Namor, Iceman, Beast, Wolverine and Emma Frost). While he no longer continues to openly question every move that Cyclops makes, he is still concerned about some of his leadership decisions. Xavier had wanted to return to the mainland to clear his name, but in the aftermath of Osborn declaring Utopia as a mutant detention area, Cyclops refused to let him leave, stating that it would be a tactical advantage to have him as an ace in the hole in case the need arose. To that end, he has kept Xavier out of the field and instead relied on Emma Frost, Psylocke and the Stepford Cuckoos respectively for their own psionic talents.<ref>''Uncanny X-Men'' #515.

Xavier does not believe it, and attacks Magneto telepathically, causing Cyclops to force him to stand down.<ref>''Uncanny X-Men'' #516. Marvel Comics.</ref>  He later apologizes to Magneto for acting out of his old passions from their complicated relationship, which Magneto accepts.<ref>''Uncanny X-Men'' #520. Marvel Comics.</ref>
