A rescue mission to Universe 199999b became a battle against Mephisto, Onslaught, Apocalypse, and the Void, while Thor uncovered Immortus’s plot to erase the universe and threaten Loki. As the multiverse began collapsing, Thor fought the Time-Keepers and Valeria’s team faced an apparently unstoppable force with only seventy-two hours to survive.

• Wong warned Peter-B’s group that Mephisto was targeting them, but the demon soon attacked Kamar-Taj with corrupted versions of their allies and offered Peter-B a chance to change the past in exchange for his soul.
• Tony and the Avengers crossed into Universe 199999b to rescue Morgan, Peter, and Sentry Robert, then fought Mephisto, Wanda, Ghost Rider, Onslaught, Apocalypse, and the Void-controlled Sentries as the universe began collapsing.
• Kara, Dark Strange, Classic Loki, and Galacta joined the battle, but Mephisto’s arrival coincided with the erasure of the universe and the disappearance of several enemies.
• Thor defeated the Cancerverse heroes and a Kang variant, then traced the threat to Immortus, who was using the Eternity Crystal to erase Universe 199999b and remove Thor from existence.
• Thor resisted the Crystal’s erasure, destroyed Immortus’s forces, took the Crystal, and learned that Loki had drawn the attention of a greater threat at the end of time.
• The Time-Keepers blocked Thor from reaching Loki, so Thor killed Ast, Zath, and Vorth while Jean Grey escaped through a rift to help Loki.
• Valeria warned Emma that the multiverse was finished, and she, Reed, and Doom found that an expanding white force was erasing universes with no known way to stop it.
• With the multiverse’s destruction projected within seventy-two hours, Doom offered Valeria refuge in Latveria, but she refused to abandon Frost City, and Franklin said someone had gone to fight the force.
