Years after the Battle of Manhattan, Earth's Mightiest Heroes have gone their separate ways and faded from memory. Many have started families and left their old lives behind them. But with the world once again in danger, who will protect it?
The Avengers' children - all as different as night and day - form the Generation. They seek to protect humanity, and together learn to bypass obstacles, overcome fears, and let go of what is dear to them.
The incident with Loki is over, but ever since then, trouble has been brewing in the dark. Just when the world needs them most, the Earth's mightiest heroes aren't available... but their children are.
