Harold Attinger is a former CIA agent. He is the Commander and the Founder of the Cemetery Wind operation unit and the main antagonist in Age of Extinction.
He’s lived his life in the shadows for 30 years (1987-2016) in the service of his country, and he likes to be unremarkable yet very efficient. Hell-bent on eliminating the presence of the Transformers on Earth, he mercilessly stalks human mechanic Cade Yeager and his daughter Tessa, due to their alliance with the Autobots. He works alongside a Transformer bounty hunter for the duration of the movie. He is given the Seed, a Cybertronian bomb built by the Creators that is able to turn the surrounding landscape into Transformium, an unstable metal the transformers are made of, by Lockdown after he captures Optimus Prime. Attinger attempts to give the Seed to Joyce in return for his payment, but Joyce leaves the scene, knowing that Galvatron wants that Seed to rebuild his army. At the end of the film, Galvatron seemingly retreats as his army is destroyed and Lockdown returns to fight Optimus. Attinger notifies Lockdown of the situation, the location of the Autobots and the Seed they have stolen. He corners Cade with a gun while Optimus fights Lockdown and he rants about how it takes patience to make a man and to work in the shadows to protect all humans. He claims that there are no good aliens or bad aliens, it's just the humans and them. He says to Yeager, "You chose them" and is about to shoot Yeager, but is quickly shot in the chest by Optimus, killing him on impact and avenging the deaths of the Autobots he had killed.
