William "Bill" Fowler

Special Agent Willian "Bill" Fowler was a former Army Ranger before the Transformers arrived on Earth. Now he's the tough-talking, robot-dissing designated liaison between the United States government and the Autobots, who's got the guts to face down the Decepticons himself. And he doesn't need any military escort! He can pilot his own damn helicopter and jet!

Though Fowler is leery about trusting the Autobots to handle the Decepticons by themselves and believes that Earth can defend itself, he seems to accept them after they saved his guts. He's come to appreciate what they can do, and all the other times they've helped him out. Thus, when the Autobots need air support or a hand with some red tape, Fowler leaps into action. If there's anyone you'd call a soldier, it's him.

He is also in charge of Unit:E.
