Amy Santiago

<p><span>Chief </span><strong><span>Amy Santiago</span></strong><span> (portrayed by Melissa Fumero), is a main character in all eight seasons of the show. She started the series as a Detective at the 99th precinct, with the ultimate goal of becoming the youngest Captain in the NYPD. She was promoted to Sergeant in season 5 and became Commander of the Uniformed Officers at the 99. In the penultimate episode of the series, she far surpasses her original goal of Captain and is promoted to the rank of Chief, working on the new Police Reform Program she developed with her mentor and father figure, Deputy Commissioner Raymond Holt.</span></p><p style="text-align: start"><span>Amy is incredibly ambitious and driven, striving for perfection in nearly everything she does. She is also highly competitive, doing whatever it takes to win a bet or competition, often against her partner-turned-husband, Jake Peralta. At the end of the series, Jake becomes a stay-at-home father to their son Mac, whom she gave birth to in the season 7 finale Lights Out, so she can do her job without guilt or regret.</span></p>
