He mostly lives for simply having a good time and relaxing, which he achieves occasionally through selfish acts like lying or cheating. Rigby is hyperactive and extremely mischievous, which sometimes puts him at odds with Mordecai. He has been best friends with Mordecai since childhood and is more prone to slacking off than Mordecai is. Rigby (voiced by William Salyers) is a 23-year-old anthropomorphic brown raccoon who works as a groundskeeper at The Park.

Head writer Matt Price, on Reddit, gave her the name Stef when asked about it, and writer Owen Dennis stated on Tumblr that there had not been previous plans to give a name to the character. Mordecai's wife was not given a name in the show. He opens a successful exhibition and meets a bat woman whom he eventually marries and starts a family. In the epilogue to 'A Regular Epic Final Battle', Mordecai quits The Park, parts ways with Rigby, moves to New York City, and returns to making art. He is shown to have an outgoing mom, who embarrasses him around his girlfriends and also made a highlight reel of Mordecai's most embarrassing moments, as seen in 'Maxin' and Relaxin''. In the episode 'Camping Can Be Cool', it is revealed that he attended art school before being employed at The Park however, he did not finish school due to his bad portrait skills, which were revealed in the episode 'Bad Portrait'. He eventually decides to take a break from dating in 'Dumped at the Altar', after his relationship with CJ didn't work out. CJ and Mordecai's relationship is strained due to CJ seeing Mordecai and Margaret having fun together on several occasions. Mordecai later bumps into CJ at a New Year's Eve party and they start dating soon after. Mordecai and Margaret finally begin to date in the fourth season until Margaret decides to leave for college, thus ending their relationship and causing Mordecai to go into a depression. Though the two have a lot in common they part ways at the end of the episode. He attempts to date other people in 'Yes Dude Yes' and meets CJ. Mordecai had many failed attempts at starting a relationship with her due to either his own nerves or Margaret having a boyfriend at the time. Mordecai would often hang out with her, along with Rigby and Eileen Roberts. Mordecai's romantic life is the subject of several episodes, particularly his crush on Margaret Smith, a cardinal who worked as a waitress at a local coffee shop. However, he is usually quick to apologize to others if he has hurt them and occasionally takes the lead in fixing a situation. He can sometimes become caught up in his emotions, often letting them get the better of him. Mordecai loves to play video games and is a better player than Rigby, he also demonstrates decent strength, such as carrying large boulders, fighting the death bear, never getting hurt by Rigby's punches, and being able to punch Rigby across an entire room with ease. However, Mordecai usually sides with his friend, occasionally going along with Rigby's attempts to get out of work and the two generally stick together through their adventures. Even though Mordecai dislikes his job, he is often willing to put up with it begrudgingly as opposed to Rigby, who is more open about his hatred towards his job and prone to avoid work as much as possible. Mordecai is more conscientious, intelligent, responsible, and mature about his actions than Rigby is, which sometimes leads to him opposing Rigby when he is the cause of some kind of chaotic problem, albeit unintentionally. He has been best friends with Rigby ever since childhood. Quintel) is a 23-year-old anthropomorphic blue jay who works as a groundskeeper at The Park.
