Brooklyn Nine-Nine: 10 Best Characters Only In One Episode
2. Jack Danger
Of course Jake Peralta was excited to work with someone named Jack Danger. It's exactly the kind of thing he became a cop for, but all that excitement went away when he found out it's actually pronounced Donger. His disappointment went even further when he actually started working with the guy.
Played by Ed Helms, Danger is an obnoxious agent for the United States Postal Inspection Service, and has an ego far too big for the job he does. He looks down on Jake, believing that he outranks him, refuses to use email in any scenario, and completely denies the true meaning of the phrase 'going postal'.
'Jackie' even goes so far as to call 'USPIS' Benjamin Franklin's greatest achievement, the crown jewel of the law enforcement system, and the nation's first defence in the war on terror. Not only was he insanely annoying, he physically stopped Jake from chasing a criminal because he wouldn't have been the one to arrest him, then blamed him for not doing his job properly.
Of all the people Peralta has come into contact with, no one has infuriated him more than Donger, which makes it so much more fun to watch.
