After Greystone, a member of Havok's X-Factor team, develops temporal insanity, he attempts to build a time machine to return to his timeline and be reunited with his mother who, in all probability, does not exist anymore. Havok attempts to stop him, but the machine explodes, supposedly killing both men. However, at the instant of Havok's death, a Havok from an alternate reality also dies after being shot in the chest by a Sentinel. Havok's spirit finds its way into his counterpart's body and he wakes up in the Mutant X Universe. Here, he is the leader of a mutant team of heroes dubbed "The Six" (who are altered versions of his friends from Earth-616), the husband of Madelyne Pryor, and the father of Scotty Summers.
