===Deadly Genesis===
Xavier returns when Cyclops' and Havok's long-lost brother, [[Vulcan (Marvel Comics)|Vulcan]],<ref name="Deadly Genesis #1-5"/> is revived by the Collective energy released as a result of the "House of M" incident. Vulcan then attacks the X-Men. Xavier, now depowered but able to walk in the wake of "House of M", reveals that he had gathered and trained another team of X-Men (this one composed of students of [[Moira MacTaggert|Dr. Moira MacTaggert]]) sometime between the original team and the new X-Men team introduced in ''Giant Size X-Men'' #1. This team included Vulcan as a member. Like the "Giant Size" X-Men team, McTaggert's former students were sent to rescue the original X-Men from Krakoa, the living island. However, after rescuing Cyclops, McTaggert's former students were seemingly killed. Upon Cyclops' return, Xavier removed Cyclops' memories of the death of Vulcan and his teammates and began assembling the "Giant Size" X-Men. Vulcan skirmishes with the X-Men and eventually flees into space.

In spite of Cyclops' feelings, Xavier forms a new team including [[Havok (comics)|Havok]] and [[Darwin (comics)|Darwin]], the lone other survivors of Moira's students.<ref>''Uncanny X-Men'' #475</ref> Xavier seeks to confront Vulcan before he can enact his vengeance against the Shi'ar empire, which killed Vulcan's mother. While en route to the Shi'ar homeworld, Xavier is abducted and is later thrown into the [[M'Kraan Crystal]] by Vulcan. Darwin follows Xavier into the crystal and pulls Xavier out. This somehow restores Xavier's lost telepathy. With help from his longtime lover, Lilandra, Xavier escapes back to Earth with several of his X-Men.

Upon Xavier's return to Earth, as seen in the ''[[World War Hulk]]'' storyline, he begins to search for lost mutants such as Magneto. Charles' search for more mutants is interrupted by the [[Hulk]], who was sent into extraterrestrial exile by [[Illuminati (comics)|the Illuminati]], a group of powerful superbeings to which Xavier belongs. Xavier had no part in (and did not know of) the Hulk exile decision, but Xavier admits to Hulk that he would have concurred to a temporary exile so [[Hulk|Bruce Banner]] could be cured of transforming into the Hulk. However, he also tells the Hulk he would not have agreed to permanent exile. Xavier attempts to surrender to the Hulk, but after viewing the X-Mansion's large graveyard dedicated to post-M-Day mutant deaths, The Hulk concludes the mutants have suffered enough and leaves the Mansion grounds on his own accord. While the X-Men tend to the wounded, Cyclops finally forgives Professor X.
