Iron Man realized that if anything happened to the entire Avengers team that the world would need another group of Earth's mightiest heroes. He looked through the files of various superheroes and chose a team he thought would work well together.
One day, Kang came from the future in another attempt to conqueror the planet. This time he seemingly killed the entire Avengers and Iron Man's protocols went into affect. JARVIS gathered the chosen team. Together they fought Kang. Spider-Man found that the Avengers were in a temporal void and released them. The two teams defeated Kang.
