Cop Rick shares the general appearance of Rick Sanchez, though he wears the Citadel police officer's uniform.
Cop Rick was shown to be a rarity among Ricks, in that he actually had a sense of honour and responsibility. He upheld a strong sense of justice, and took his job seriously, following codes of regulation and various protocols, going as far as to call out Cop Morty, who was his senior partner, out on his dishonest code violations.
Although initially sharing the ideas of mistreating Mortys as other Ricks, Cop Rick was thrown off by the sheer tenacity of Cop Morty and was left horrified by his actions against other Mortys in Mortytown, apparently leading him to "go soft." This behavior caused him to let his guard down and literally get stabbed in the back by another Morty. In spite of his initially shown disregard for Mortys, he continued to do his job honestly, regardless of if he was dealing with a Rick or a Morty, even showing a kinder side to Mortys, even though it resulted in him getting stabbed.
Upon meeting Big Morty at The Creepy Morty club, despite being offered a bribe to stay quiet, he held down the law and caused a shootout in the club. When Cop Morty killed Big Morty, Cop Rick was forced to kill his partner, and surrendered to the police, expecting and accepting punishment. Instead, he learned he had been cleared of all charges due to a change in parliament, leaving him disturbed that no justice had come from his recent adventure.
