Synopsis for "Everything Is Sinister! (Part 1)"
Two tourists stand at the feet of the Dreaming Celestial. A man reads some things from a pamphlet about San Francisco in the company of a woman. Suddenly, Mr. Sinister appears and kills the woman. The man begs for his life, but Sinister kills him anyway, saying that he is only human. He then disappears through a portal.
During the next day at Utopia, Scott and Emma attend to a meeting with Magneto, Danger, Colossus, Magik, Storm and Namor. As they take seats, Danger informs Colossus that Doctor Nemesis reinforced his chair in case his other self should make an appearance. Scott says that despite the schism with the Westchester school, their overall situation has not changed and mutant prejudice is still a major issue. Scott has chosen them to be his "Extinction Team" so that they can prove that mutants are necessary for humanity's survival. Storm expresses skepticism at the idea, but Scott replies that the team must do their best to remain the good guys.
During week one, the diverse X-Teams continue their usual activities.
In week two, Scott and Emma receive an emergency call from Abigail Brand and go to the Peak. Brand tells them that the Dreaming Celestial's energy signature has radically changed and the X-Men have to investigate. She also says that she was going to contact the Avengers next, but Cyclops tells her not to, stating that they are not prepared for that kind of emergencies.
Extinction Team is teleported by Magik to the Dreaming Celestial, and suddenly, the Celestial's head separates from its body, taking the form of Sinister's head. Emma telepathically connects Scott's mind to that of Sinister. Scott asks Sinister what he wants, and Sinister replies that he wants the same as Scott. Then, the Celestial head releases an energy blast from its diamond at Emma, however, Emma changes into her diamond form to protect herself.
Then, Emma calls Namor for help, and Namor swiftly brings the head down. Suddenly, a swarm of battle-bots appears and attacks the X-Men. One robot blasts Colossus to another part of the city, while another blows Emma's arm off. Cyclops tells Hope to mimic Emma's telepathy to communicate a message. Cyclops instructs Magik to help Colossus and the reserves to contain the robots.
Magik reaches Colossus, who transforms into the Juggernaut. Colossus uses one of Magik's portals to return to the battle.
Doctor Nemesis tells the X-Men that the Celestial is dividing itself in micro-Celestials because it lacks an electro-magnetic structure. Magneto uses his powers to stabilize the Celestial and maintain its natural state. Danger locates the Celestial's head in the Palace of Fine Arts.
There, Sinister has used the head to transform everyone in the city into duplicates of himself.
