On a day unlike any other, Earth's mightiest heroes must ban together to take down a threat no single hero can handle. But when even their combined strength fails, will they turn to a potentially greater threat for help?
Ten years ago, Franklin Hall was part of S.H.I.E.L.D.. He was tasked by Nick Fury to recreate the Super Soldier Serum. However, an experiment goes too far and turns Hall into Graviton. Graviton nearly killed everyone around him so Fury put him in the Raft where he could hurt no one.
With the security of the Raft, Vault, Big House, and Cube down, Graviton is able to escape. His first act is to seek revenge on Fury. Iron Man, Thor, Giant Man, and Wasp arrive to help but cannot stop the supervillain. They are soon joined by Hulk and together are able to stop Graviton. After saving Hulk from incarceration, the group decide to ban together to recapture the other escaped inmates.
