A tall blue jay who works with his friend Rigby at the park. Between the two, Mordecai is the more mature, although he will sometimes play along with the more enthusiastic Rigby's hijinks.
Also whenever Rigby's in danger or Mordecai's worried about him, he sometimes stretches out his wing and cries "Rigby!"
Can't Get Away With Nuthin': The main element of a lot of episodes is Mordecai and Rigby attempting to shirk some responsibility and usually doesn't resolve unless they own up to what they've done.
Characterization Marches On: Yeah, he still punches Rigby in the arm once in a while when he saids something jerkish or idiotic and would still punch him when they get into a physical fight(but occasionally and aka "Weekend at Benson's") but he became less abusive torwards Rigby in comparison to the earlier episodes(when's the last time you ever saw them play punchies??) Also helps that Mordecai KNOWS his best friend may die young!
Cheated Angle: He's almost never shown head-on, and even when he is, his head crest is still angled.
The Slacker: Doesn't appear so at first, but often joins in with Rigby's escapades for the sake of rivalry or just for the hell of it. "Just Set Up The Chairs" is a prime example. Since season two had started, he seems to be more inclined to go along with Rigby.
A much shorter raccoon and Mordecai's frequent coworker. Being energetic and immature, he's usually the one who instigates any sort of trouble that Mordecai or the other characters get into. He is a high school drop-out who never received his diploma, and Mordecai thinks that's pretty funny.Has a very tall, younger brother named Don, who is an accountant.
Adorkable: Not as much as Eileen but has his moments.
At one point he eats so much junk food his body literally quits on him.
Brilliant, but Lazy: Moreso than Mordecai. The only reason he hasn't been fired is because he's actually efficient when he gets a job done.
Butt Monkey: Possibly one of the best examples, every episode will result in some pain coming to him or even dying in some episodes. Add in his physical weakness where he can't retaliate and near everyone can beat him up and he's almost The Chew Toy.
Benson: First on the agenda is trophy talk. Who gets the trophy on what day? I think the schedule is more than fair.
(Everyone on the team is scheduled to have the trophy for two days each week, except Rigby who only has it one day.)
Can't Get Away With Nuthin': Along with Mordecai but Rigby mostly makes problems by trying to be cool or doing something petty that he thinks is irrelevant. Naturally, it will always come back to get him.
Catch Phrase: "Ohhhhhh!", "Check it" and "STOP TALKIIIING!".
Cheated Angle: He, too, is rarely seen from the front.
Death Is Cheap : Rigby has died at least three times (expelled from his own body, thrown into a time void, crushed during an arm wrestling match), being revived each time.
Funny Animal: See above. He digs through trash and runs on all fours when in a hurry.
Jerk with a Heart of Gold: Driven home in the hot dogs episode, where Rigby truly seems to care for Mordecai after they both get trapped in the freezer.
Generally speaking, it seems Rigby really likes Mordecai.
Also in the episode "A Bunch of Baby Ducks", where Rigby insists on keeping the ducks, and calls them his.
Another example is at the end of "Do Me a Solid" where Rigby destroys the only video evidence of the humiliating solid he made Mordecai do.
The Slacker: Though, in some instances (like "Death Punchies" or "Caffeinated Concert Tickets") he's shown to have all the ambition necessary to achieve his goal.
An anthropomorphic gumball machine, and Mordecai and Rigby's boss. Although he generally seems mildly annoyed, at the worst he can get really pissed if Mordecai and/or Rigby have messed something up.
And again in "Stick Hockey" when he arrives just in time to finish Mordecai and Rigby's stick hockey deathmatch and is revealed to be a master at the game.
Got yet another one in "Cool Bikes" when he saves Mordecai and Rigby's lives by attacking the judge that was sentencing them to death and aiding in their escape.
He got a small (yet awesome) one in "Karaoke Video". Mordecai and Rigby are attempting to steal the video of them dissing on their coworkers. Some brawls between the bars employees and them eventually turn into an all out bar brawl. Near the end it shows Benson hopelessly looking at the ridiculous warfare just as the tape lands in front of him. He picks it up curiously and the owner of the bar punches him in the face and orders him to give it back. He then smashes the karaoke tape right into the owner's face, knocking him out and destroying the tape in the process. He basically saved Mordecai and Rigby's necks from himself without even realizing it.
Benson: You want it?! FINE! TAKE IT THEN!
Catch Phrase: "You're FIRED!!" by itself, or in a sentence containing those words.
The Cavalry: The guys are losing to a physical manifestation of an Ear Worm that they're battling by playing a counter Ear Worm. When Benson arrives, Mordecai assumes he's there to yell at them for messing up the park with their battle. He is there to yell at them, but for forgetting a key part of an Ear Worm: the beat from the drums which he plays.
Character Development: He's noticably more tolerent of Mordecai and Rigby after "Benson Be Gone", not getting as angry at them for when they mess up. He even came to their rescue in "This Is My Jam".
Also shows in "Jinxed" when he subverts his Rant Inducing Slight because they apologized for slacking off, where before he'd not have given them the time of day. He did lose it earlier in the episode when Rigby was intentionally enraging him trying to break his jinx, but Benson didn't take it out on Rigby and instead vented his rage elsewhere.
Newer episodes even had him lead the group in downtime activities, like a weekly game night and paying for everyone at a bar, even Mordecai and Rigby.
It's revealed in "Stick Hockey" that he used to be a champion stick hockey player until ten years prior to the episode when his apprentice Dave was killed in the final round of a tournament. Now he sees himself as a loser who wasted his life on stick hockey and now he's wasted his life in a dead-end job.
Hair-Trigger Temper: Has very explosive outbursts that often end with "...OR YOU'RE FIRED!!" Generally seems to be ready to blow his cool at the drop of a hat anyway.
"Think Positive" makes this trope literal. If he holds in his anger too long, he starts burning thing at his touch and destroying everything until he's let it out.
Jerk with a Heart of Gold: Not quite as much as Rigby, but there are a handful of times where it's hinted that he has a softer side. Although in his case, he's not so much a jerk as he is constantly displeased with Mordecai and Rigby's slacking and screw ups. The "jerk" side wanes somewhat after "Benson Be Gone".
On a couple of occasions Benson has claimed that he does something tough on Mordecai and Rigby out of concern for their future and wants to instill some sense of responsibility in a pair of irredeemable slackers.
It's still there, though, as seen in "Stick Hockey", where he throws out Mordecai and Rigby's stick hockey game (even though they finished all their jobs) just because he didn't think they'd finish (although he does regret his actions, and even helps get it back).
At the end he admits he did so because he was afraid that they'd end up wasting their lives playing the game like he felt he did with a part of his own.
No Indoor Voice: If you get him really mad, of course. "Think Positive" made it loud enough to make Mordecai and Rigby go deaf!
Calvin Wong's Formspring also spoiled (by accident) that he's a huge fan of rock music, in particular "Foghat, Hall and Oates, Asia, Toto, and Phil Collins."
Not So Stoic: As seen in his scene in the ending of "Mordecai and the Rigbys" where he nonetheless gives them both a standing ovation after their disastrous performance and Mordecai's speech.
Seen again in "This Is My Jam". He's initially angered by the omnipresent ear-worm, but willingly joins in on drums to help Mordecai's improvised band defeat it.
Papa Wolf: Despite his annoyance with the main duo and the rest of his employees at times, he's nonetheless very protective of them, evidenced in episodes such as "Benson Be Gone", or "Stick Hockey"
Perma Stubble: Word Of God is that his gumballs are supposed to resemble this, as a visual sign that he is over-worked.
Rant Inducing Slight: Benson doesn't get REALLY upset at Mordecai and Rigby until after whatever horrible situation they created has been resolved.
Decreased in number after "Benson Be Gone", after which it happens noticeably less often.
The Slacker: If you can believe it, even moreso than Mordecai and Rigby. In "Benson Be Gone," the two try to teach Benson it's okay to slack off a little as long as you get back to work, but Benson takes this as meaning it's perfectly fine not to work at all. If he doesn't have a constant stream of work, he won't work at all.
The son of the park's wealthy owner who's been sheltered all his life. He's a humanoid lollipop from Lolliland. He's mostly there to be comic relief. Also, Mordecai and Rigby can get away with almost anything around him because he doesn't know better. The episode "Dizzy" reveals that he has an extremely dysfunctional relationship with his father, who's as scary as Pops is kooky.
Born in the Wrong Century: Though, since he is from Lolliland, it's possible that his way of dress and behavior is normal where he's from.
Perhaps not- as seen in "Skips Vs. Technology", he's over 100 years old.
Character Overlap: He first appeared in a pre-Regular Show sketch that JG Quintel made.
In "Don", he believes lollipops are the same thing as money, and are therefore suitable for paying bills, which gets the park into some trouble. The exact same situation is the plotline for the aforementioned sketch.
He briefly appears in the other JG Quintel sketch (2 in the AM PM) as one of their hallucinated forms.
The Chick: Despite his many quirks, Pops is a sweet, gentle, child-like man who's the type to have a kind word for anyone when they need it, and to help a baby bird back into its nest.
Cloudcuckoolander: The prank call episode suggests that this may come from him being run over by a golf cart, followed by a cell phone-induced brain tumor.
Crouching Moron, Hidden Badass: In "Really Real Wrestling" it turns out he used to wrestle. Turns out he's pretty good at it too.
Pointy-Haired Boss: He's extremely negligent and a more than a few episodes stem at least in part to him letting something happen or trusting Mordecai and Rigby too much. He also has a problem with failing to see how much Mordecai and Rigby fail as employees.
Genius Bruiser: At times Skips seems to be able to improvise very quickly, as seen in "The Power" near the end. Likewise, his quick thinking brings about the avatar by which Rigby destroys the Destroyer of Worlds.
Meaningful Rename: He always skips rather than walking. It turns out his real name is not Skips, but Walks. He changed it because he got tired of everybody asking him why he skips everywhere instead of walking.
Mr. Fixit: According to "Skips vs. Technology", he's in charge of basically any repair work needed around the park, a role he fills quite well... at least, when it comes to physical stuff. Fixing a malfunctioning computer seems to be a bit beyond him.
My God, What Have I Done?: Gets this in "Over The Top" after killing Rigby. He's so guilty that he puts his eternal soul on the line to win Rigby's soul back from Death.
Seen It All: Very few things seem to faze him and he somehow knows just how to deal with all the insanely weird things the park has to deal with. Justifed possibly due to Older than They Look.
The Smart Guy: Fills this role whenever Muscle Man has The Big Guy role. He can fix almost anything (except computers), and comes off as the wisest of the team.
Gag Boobs: Muscle Man's bitch tits. He even got smacked in the face with them in one episode.
Genre Savvy: "This is the future, bros. There's gotta be a time machine!"
He was right.
Jerkass: Originally, Muscle Man was a Jerkass to Mordecai and Rigby, culminating in My Mom. However, he's become a nicer person since then, willingly working with Mordecai and Rigby in "The Night Owl".
Jerk with a Heart of Gold: Although he's still an immature idiot, he's never mean towards women. Plus, he recently started to willingly work with Mordecai and Rigby and view them as friends.
Karma Houdini: They slack off worse than Mordecai and Rigby, but Benson trusts them more because they actually bother to tell him when they're going on break.
The Quiet One: High-Five Ghost spoke only one full sentence in the entire first season. The episode "Muscle Woman" has High-Fives talk more than usual due to Muscle Man isolating himself, implying that he usually doesn't talk because Muscle Man just does all the talking for him.
As a recent episode shows, apparently he doesn't talk because he's Jinxed and Muscleman will punch him if he ever talks around him. Rigby broke his jinx and afterwards he talks much more often.
Screw the Rules, I Have Connections!: As one episode shows, Muscle Man has a lot of friends around town. Heck, a police officer chases afters him just to tell him how awesome he is.
Talk to the Fist: In "Night Owl", after returning to the past after the title character froze him, High-Five, Mordecai, and Rigby for several hundred years, the Night Owl starts chewing them out for ruining his plan. So Muscle Man knocks him out cold mid-rant.
A red-breasted robin who works at a coffee shop. Mordecai has a crush on her.
All Girls Want Bad Boys: The only time Margaret has shown to have an interest in Mordecai was when he "blew her off" (Mordecai at the time was suffering a Heroic BSOD from seeing Pops naked).
Interspecies Romance: Three of her boyfriends so far have been humans (one of which was apparently a giant), and she almost went on a date with Rigby in an alternate timeline.
Ms. Fanservice: She tends to dress rather provocatively.
Non-Mammal Mammaries: "Lady pecs", in Mordecai's words. She even gets to show a little sideboob in the concert episode, and cleavage in others.
Pink Girl, Blue Boy: Pink Girl to Mordecai's Blue Boy. (Technically, she's bright red, but it still qualifies)
The Smurfette Principle: In the entire first season, she was in only three episodes (one of which was only via dream sequence) and had less than three minutes' screen time combined. However, she's gotten a lot more screen time in season 2.
What Does She See in Him?: All of the men she seems to date are obnoxious jerks, who seem to irritate her. Except for Rigby, who she really likes.
Margaret: Ugh, what boyfriend? I'm not seeing anyone right now. Guys are jerks.
Mordecai: Gah, I know, right? Guys are the worst! (Flashes Rigby a silent "Ohhhhhh!")
Eileen
Voiced by: Minty Lewis
An adorably sweet mole girl who works at the coffee shop with Margaret. Has a crush on Rigby.
Action Survivor: Proves herself to be one of these in "Camping Can Be Cool". Without her, Mordecai, Margaret and Rigby would probaby not have made it out of those woods alive...
And in "Camping Can Be Cool" she admits to going through a phase where she got lost in the woods a lot the previous year, as well as playing with several snakes.
