William Fowler

Fowler is a human from the Transformers: Prime continuity family.

Someone buy him a longer tie.

Special Agent William "Bill" Fowler is the type of guy that Theodore Galloway wishes he could be. He's the tough-talking, robot-dissing designated liaison between the United States government and the Autobots. And he doesn't need any military escort! He can pilot his own damn helicopter! Fowler is leery about trusting the Autobots to handle the Decepticons by themselves and doesn't believe that Earth can't handle its own mess, but for now, while he chews them out and slags them off, he's willing to let them have a chance.

“	Pretty big bearings... for a human.	”

Agent Fowler visited Autobot Central Command to chew the Autobots off over mass traffic accidents caused by several odd vehicles, and then demanded to know if this meant the Decepticons were back. When Optimus Prime confirmed this, Fowler stated it was time to "wake up" the Pentagon; he was notably unimpressed by Optimus's claim that only the Autobots could stop the Decepticons, clearly not believing it, but to avoid mass human casualties he agreed to give them a shot at sorting it out.

Bulkhead angrily told Fowler that the Autobots knew how to use appropriate force, but when the agent was gone he noted with respect that Fowler had bearings. Prime noted that Fowler's attitude was due to being afraid for his planet. Darkness Rising, Part 2

Another explosion had Fowler returning to the Autobot base, but found only Bulkhead there. When Miko's guitar gave away the kids, he announced he was going to take them into federal custody, but Bulkhead prevented him from phoning his superiors. He stormed out and took off in his helicopter, making a report by radio. Unfortunately the transmission was intercepted by the Decepticons, who captured him and dangled him from chains. Fowler proved difficult to interrogate, so Starscream got out an energon prod to soften him up. Darkness Rising, Part 3

Notes

• Which agency Fowler's a Special Agent for isn't stated; since he specifically refers to the Pentagon as who he'd talk to, he's presumably with a Department of Defense agency like the Defense Intelligence Agency or the Military Intelligence Corps.
• The Autobots refer to him as their liaison with "the outside world", though he appears to just represent the United States.
• Fowler must have one awesome rank if he can decide on his own whether or not the Pentagon is to go on full alert!
