- Iron Avengers - A team of robots built to replicate the powers of their counterparts to destroy Ultron. They were turned against their creator.
The team formed to deal with threats too great for any one hero. They were based out of the Avengers Mansion and used the Quinjet to travel. They eventually brought peace and many of them settled down to find love and have children. However, Iron Man's creation, Ultron, arrived and killed all but Clint, Tony, and Vision. Tony took the children to a hideout and raised them, Vision was his spy, and Clint raised his son while forming the Scavengers. Tony built the Iron Avengers to deal with Ultron. Ultron discovered the children and captured Iron Man. The children went to Ultra City, found Francis, and saved Tony. They then left to the desert to have Hulk help them. Hulk defeated the Iron Avengers and Ultron. The team then went back to Ultra City to defeat Ultron's robots.
The team was largely based off the team of Ultimate Avengers and Ultimate Avengers II. The producers felt that the audiences viewing Next Avengers: Heroes of Tomorrow would be familiar with that team because of the earlier features.
