Synopsis
In #10 Baron Zemo and his new Masters Of Evil found the Thunderbolts' Arctic base and captured Winter Soldier/Bucky Barnes. Last issue Kobik, the little girl who is a Cosmic Cube, took her friend Bucky back to the WWII past to show him the new version she created during Avengers Standoff. Lots of events didn't happen the way he remembers them, and most importantly his mentor Captain America/Steve Rogers was an agent of Hydra. Kobik hoped that Bucky would join Hydra too, and then they could continue to be great friends. When it didn't work that way she had a tantrum.
Now outside the base semi-conscious Atlas is freezing to death. His friend Jolt returned from Counter-Earth in #10 and now she jolts his heart back to work. They stagger back to the base and find it busted wide open with Kobik hovering in the air and screaming/crying.
Bucky drops from the sky at the feet of Zemo and some of his villains. Which now includes Fixer and Moonstone who have switched sides. Bucky and Zemo start to fight.
The other 2 Tbolts, Mach-X and Songbird, are surrounded by Wrecker and his Wrecking Crew. As they fight Mach-X tries to convince the villains that they can't trust Zemo. But then Thunderball breaks Songbird's ribs.
Kobik has whipped up a whirling storm which has already whisked Klaw away. Whiplash saves himself by tethering his whip to the ground, and Man-Killer is hanging on to his foot. But he kicks her free and she gets zapped by a bolt of lightning.
Jolt zaps Tiger Shark as Atlas tries to talk Kobik down. Fixer realises the Cube is starting to tear reality apart. He thinks he may be able to figure a way to fix things.
The Wrecking Crew beat on Mach-X while Wrecker prepares to kill Songbird with his crowbar. But then the Ghost phases out of a wall and sticks a bomb on his back. We learn that he's here to hack Fixer's computer system, but he can't do that if this battle destroys everything.
Winter Soldier wins his fight with Baron Zemo. But then Moonstone zaps him in the back. This is a bit much for Fixer, but Karla says Bucky's tactic of befriending Kobik didn't work. She's too dangerous to leave loose.
Atlas somehow has Kobik in a force bubble. Jolt is trying to siphon off her energy but there's too much. Fixer has created an array of force projectors which he fires at Kobik. There's a large explosion. Kobik says she just wanted everyone to be happy. And then she explodes.
Zemo KO's Bucky and gathers his remaining crew. The Wrecking group break free of some rubble and claim Mach-X is dead. (Although I think I saw him being blown free with Songbird.) Fixer has bad news for Zemo - the Cosmic Cube has broken into pieces and the fragments have been widely scattered. Zemo orders him to track and retrieve them. Atlas also survived. Zemo welcomes him (back) the the MOE, and the eternal follower Erik falls in line. He gets to carry the unconscious Barnes.
After they've gone Songbird struggles out of a snowdrift. But she can't find Mach-X, so she trudges off into the snowscape. Behind her Ghost phases out of the snow. He finds and pockets Jolt whose energy body has shrunk.
