An adorable big black guy who once read the entire Urban dictionary in only 74 mins. so that he "could converse with the others uniformed officers" .
He's been the captain of Brooklyn 99 precint, a kind of Daddy figure for Jake Peralta and a loving husband to Kevin.
His worst enemy is Madeline Wuntch , for whom he has frequently travelled abroad "to look for new Wuntch insults" . She later demoted him from captain to cop, escalating season 7th in a crazy funny situation.
His robot personality has smoothed down more and more during the 8th seasons of the show and his straight alter-ego "Is a real dog!" (quote by Jake Peralta).
He's really loved by all the squad and makes a great character who loves to send criminals, alias. PUNKS, in prison.
Grandma: "Derek, did you steal 20 bucks from my wallet again?!"
Derek: "...nope"
Grandma: "I know you are lying, You, PUNK!"
Derek: "Gosh, you really sound like Captain Raymond Holt"
"There is nothing more intoxicating that the clear absence of a penis" - Captain Holt alter-ego.
