I'm not going into detailed spoilers in this one but the long and short is
-The heroes manage to break out White Skull
-The battles between the inverted heroes and villains continues
- Deadpool manages to change Apocalypse's mind and he helps the heroes. Thor is chasing Loki on the moon until they run until mjolnir and Loki manages to wield it and beat Thor down (ugh!)
- The battle on Earth rages on until Scarlet Witch, Quicksilver and Dr Voodoo appear on the scene. Doom, Wanda and White Skull work together to reverse the inversion but Iron man has devised a force field to protect himself. However, he covers up Havok and Sabertooth too both of whom stay inverted.
- Loki is reverted and he can't lift mjolnir again while Havok kidnaps the Wasp and forces her to transport both of them into the microverse. Meanwhile, Stark, Doom and Red Skull escape.
- A news broadcast shows a video where the Axis of villains take responsibility for the actions of the inverted X-men and Avengers. It's explained they did this while inverted to prevent the blame from falling on the Avengers and the X-men.
- The issue ends with Sabretooth writing a letter about how good he now is and how he's going to try be a better person.
