The Wreckers are a group of Autobots in the 2011 film Transformers: Dark of the Moon and disbanded before Transformers: Age of Extinction and they returned as minor protagonists in Transformers: The Last Knight.
Dark of the Moon (2011)
The Wreckers, Leadfoot, Roadbuster and Topspin were a trio of engineering geniuses who came to Earth aboard the Autobot spaceship Xantium. The Wreckers rarely left the secret Autobot launch facility at Cape Canaveral, partially because caring for the ship dominated their time, and partially because they were assholes. The Wreckers helped engineer the Autobots' feigned exile from Earth and assassination by Starscream, and later participated in the battle for Chicago. They proved effective, if vicious, fighters, dismantling their fair share of Decepticons, challenging Shockwave and rescuing Optimus Prime from an embarrassing situation. All three of them would continue fighting and would be among the surviving Autobots, accepting Earth as their true home.
Age of Extinction (2014)
After the Battle of Chicago, Harold Attinger formed a secret faction of the CIA known as "Cemetery Wind" to hunt down all Transformers regardless of faction. Leadfoot was among the many casualties of the hunt, and his death was revealed to the surviving Autobots by Cade Yeager. Hound sadly took off his hat in respect for his fallen friend and Optimus Prime vowed to kill the person responsible for Leadfoot and Ratchet's deaths. If Roadbuster and Topspin survived or not.
The Last Knight (2017)
In the years after the Battle of Chicago, Roadbuster and Topspin were given sanctuary in Cuba with Seymour Simmons. Frankly, they like to pester him to go to the Beach or play Volleyball for fun.
