There are no good robots or bad robots, Yeager! There's only us and them. And you chose them.
Who: Harold Attinger (Kelsey Grammer)
Note: A businessman who arranges a deal with the bounty hunter Lockdown to kill Autobots and Decepticons alike so they may have possession of a Cybertronian artifact called the Seed, which is capable of terraforming any environment into "Transformium". Throughout the film, he antagonizes Cade Yeager so that he may capture Optimus Prime, alive or dead. As Optimus fights Lockdown in Hong Kong, Attinger confronts Yeager telling him that Cade is essentially betraying humanity by siding with the Autobots. As revenge for Attinger being responsible for the death of his friend Ratchet, Optimus shoots Attinger with his cannon, and kills him to protect Cade.
