Synopsis / Summary / Plot
In the opening page we get the disembodied voice of Havok talking to his daughter Katie again. It's a message left for her 16th birthday, but she's obviously much younger than that when we see her inside the comic. We learn that she's not a mutant. And that Hank (McCoy - Beast) is helping to hide her existence from Eimin and the mutants.
As Earth was destroyed last issue the surviving Apocalypse Twin Eimin ferried all mutants to safety in her space ark, to their new home Planet X. Wasp, now Katie's mother, was the only non-mutant on the Ark. Havok and Wasp are trying to find a way to change history and get Earth and humanity back. Havok leaves the message because they might not survive.
Now Havok is on the run from Blob and Pyro through a crowded mall. To get away he leaps through a window very high up in the air. Blob follows and they continue to fight as they fall. But then the flying Wasp rescues her husband. But shrinking him out of Blob's grasp has used up her remaining external Pym particles.
Blob is saved from hitting the ground by Magneto. Accompanied by Toad in an aircar. Magneto refers to them as his X-Force, as they fly after the fugitives.
The duo are expecting Beast to be able to send them back in time. Meanwhile they are intending to break into the Apocalypse Ark.
Magneto turns a building in front of them into amorphous arms to grab them. But Havok gets Wasp to restore him to full size in mid-air, and he destroys the arms with a blast of cosmic energy. Then he angles himself to land on Toad's aircar, and throws the enemy out of it. But Magneto has been towing Blob, and throws him at the car like a missile.
When the car hits the ground they're almost at the Ark. Havok and Wasp intend to blow up the Tachyon Dam that stops time travel into and out of this era. (When Wasp failed to kill Grim Reaper to achieve that goal last issue, Earth got destroyed and Reaper killed Captain America. She doesn't know that since then Havok took revenge by killing Reaper.)
Havok goes to use his cosmic blast on the Dam while Wasp stays behind to hold off Blob. Jan defeats Blob with the old stinger-inside-the-ear trick. But Magneto catches up with Havok and leaves him dangling from the edge of a roof. Until Wasp's sting knocks him down and she helps Alex up.
Then Havok does destroy the Tachyon Dam. The blast sends him flying, so he's not there to prevent Magneto capturing Jan in a small metal cage.
Alex returns to Beast's lab, and little Katie playing with her toys.
The purpose of breaking the Dam was to allow Immortus to send his promised help from the future. And to allow travel back in time to prevent the destruction of Earth (and the preceding deaths). But Henry McCoy reports that the Dam still exists in the past, so they can't go back there!
And Immortus doesn't show up. But instead Kang arrives with the characters he gathered from dying timelines in #14. And accompanied by Thor.
