Plot
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.[3] 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.[4]
At first he tries to convince the others of the Six to help him return to his universe. They all still believe him to be the Havok of their universe and insist that he is lying about coming from another dimension as a way of getting back at Madelyne for some unspecified injury. Havok ultimately gives up and decides to take on his counterpart's place in this universe.[5] Scotty, who has precognitive powers, realizes that Havok is telling the truth, and addresses him as "Alex" instead of "Dad". The two quickly form a bond.[6]
A demon-possessed Madelyne sets plans to take over the world. She takes control of all members of the Six except Havok. Scotty is warned of her doings by his precognitive power, and Havok takes him and his nanny, Elektra, into hiding.[7] For months Madelyne wages war against the rest of the world while trying to open a gateway to allow a full demonic invasion. Scotty finally stops her by exorcising the Goblin Entity from her mind.[8]
The destruction caused by Madelyne serves as a spark to ignite the seething anti-mutant sentiment in the United States, and new president Graydon Creed tasks terrorist leader Nick Fury with rounding up mutants into prison camps; though the public explanation is that this is for their protection, mutants taken into the camps are immediately killed. Havok has Elektra take Scotty into hiding, while the remaining members of the Six, supplemented by new members Gambit and Captain America, set about rescuing mutants from Nick Fury's troops.[9]
At the end of the series, the Goblin Entity, Dracula, and the Beyonder converge their efforts to destroy Earth. Almost all of the heroes die in the epic battle. Havok, discovering that he is the home for the Nexus of Realities, a force of nature that binds all realities (Omniverse), uses it to wield an omniversal level of power to stop the Goblin Entity, which had merged with the Beyonder. He then fights with the possessed Madelyne and harnesses the power of the Nexus of All Realities and with a thought eliminates the Goblin Entity throughout the Omniverse. He then teleports Madelyne to her alternate universe with her son, Scotty. Fearing that somebody would attempt to use the power of the Nexus of All Realities to reshape, destroy, or alter the Omniverse; he then becomes one with the Nexus of All Realities to prevent anyone from getting this power, except himself.
