Top 50 Famous Regular Show Characters

Mordecai stands as one of the two main protagonists in the animated series "Regular Show." His enduring friendship with Rigby began in kindergarten, blossoming into an inseparable partnership as adults. The two friends work as groundskeepers at the city park, where Mordecai develops a crush on Margaret, a kind-hearted waitress.

Mordecai's romantic life takes an unexpected twist when he accidentally cheats on Margaret with CJ, another love interest, leading to a complicated love triangle. The emotional entanglement causes tension and heartbreak, ending with his breakup from CJ.

Though Mordecai usually comes across as relaxed and easygoing, he frequently demonstrates maturity, intelligence, and responsibility—especially when he and Rigby land in trouble. Despite his strong moral compass and kind nature, Mordecai, much like Rigby, often prefers relaxing with a cold soda instead of tackling hard work.

Pops, whose original name is Mega Kranus, is a transcendent being from Lolliland and holds a cosmic significance in the universe. Every universal cycle, he faces his villainous brother, Malum Kranus, in an epic battle that always ends in a stalemate, causing reality to repeatedly reset.

Upon his arrival on Earth, Pops was taken in by Mr. Maellard, who adopted him and sought to provide a semblance of normalcy. Although Pops is officially the park manager alongside Benson, his gentle, whimsical nature often finds him more at home among the staff rather than giving orders.

Known for his childlike innocence and infectious joy, Pops captivates everyone with his cheerful disposition and unique, elaborate manner of speaking. He treasures simple things, finds fascination in butterflies, and is particularly fond of his quirky car.

Despite his gentle and innocent character, Pops occasionally surprises those around him by standing his ground and demanding respect when he feels underappreciated or slighted.

Rigby is Mordecai's best friend and the younger brother of Don. As a teenager, Rigby often found himself in trouble and struggled with schoolwork, leading to ongoing disappointment from his parents. He and Mordecai were frequent targets of bullying by Jablonski, and eventually, Rigby decided to skip their high school prom.

Rigby dreamed of attending College University, but after being rejected, he faked a rejection letter to save face. Later, he was expelled following a disastrous time machine experiment. Despite being immature, impulsive, and sometimes disrespectful, Rigby ultimately cares deeply about his friends and strives to do what’s right when it truly matters.

He is extremely afraid of horror movies and is famous for his dramatic antics, like making his iconic "Shark Face" and yelling his catchphrase, "STOP TALKING!!!" After graduating, Rigby joined Mordecai as a groundskeeper at the Park, where the duo's wild adventures continued to unfold.

Skips, an immortal yeti, is renowned for his wisdom and gentle demeanor as a groundskeeper at Mr. Maellard's park in "Regular Show." Originally known as Walks, he was born sometime between the 18th and 19th centuries, bringing centuries of experience to his role.

In his younger days, Skips was adventurous and impulsive, often finding himself in trouble and relishing a wild lifestyle. However, his life took a turn when he met the love of his life, inspiring him to pursue more peaceful paths instead of confrontation.

After her passing, Skips became more reserved and introspective, using his vast knowledge from centuries of experience to help others. He is frequently sought after by the group when facing supernatural challenges thanks to his expertise.

Though Skips speaks sparingly, his actions significantly impact the team. He is often seen exercising or working in the golf cart garage, where his subtle sense of humor occasionally shines. The character is memorably voiced by Mark Hamill, adding depth and personality to Skips.

Eileen is a shy and introverted mole girl, known for her quirky and nerdy charm. She harbors an adorable crush on Rigby, a detail highlighted by Minty Lewis, and gradually develops confidence, particularly in the episode "Camping Can Be Cool," where she impresses Rigby by confidently starting a fire and sharing her constellation knowledge.

Exceptionally smart, Eileen consistently achieves straight As in her college classes. While she excels academically, she also has a cheerful, whimsical side, enjoying sea turtles and fun hobbies like rock polishing. A childhood mishap left her with a lingering fear of snow tubing.

As a child, Eileen participated in the "mole scouts" but decided to leave, wary of being called a "British dirtbag." Idealistic and driven, she even wrote "The Eileen Plan" in sixth grade—a manifesto envisioning herself as President and aspiring to eliminate peanut allergies.

During high school, Eileen was part of the pep squad but chose not to attend prom, highlighting her distinctive, relatable personality and independence.

Hi Five Ghost is a small, ghostly figure with a white, semi-transparent appearance reminiscent of a Pac-Man character. His most notable trait is a small arm and hand extending from the top of his head, giving him a unique look among the park crew.

Although typically quiet and often blending into the background, Hi Five Ghost stands out for his supportive, kind-hearted, and exceptionally logical demeanor. His calm approach helps balance the more chaotic personalities around him.

Hi Five Ghost is especially loyal to his best friend Muscle Man, frequently partnering with him in basketball games and various antics. While he maintains good relationships with Mordecai and Rigby, tensions can arise due to Muscle Man’s strong personality affecting the group dynamic.

Widely viewed as the most rational among the park employees—a quality highlighted by the resident scientist in the episode "The Button"—Hi Five Ghost also exhibits a sensitive side when it comes to matters of death, as seen in episodes like "Trucker Hall of Fame" and "The End of Muscle Man."

Mitch "Muscle Man" Sorrenstein is a green-skinned, heavyset humanoid who works as a groundskeeper at the Park with Mordecai, Rigby, and Hi Five Ghost. Despite his scruffy appearance and laid-back attitude, he's recognized by Benson for his hard work and often outperforms his coworkers on the job.

Known for his signature "My Mom!" jokes, Muscle Man loves pranking his colleagues but also shows a genuine caring side, especially towards his mother—something revealed in the episode "My Mom." His outsized ego is unmistakable, as seen in "Exit 9B," where he insists on having the largest signature among the crew.

Starla, Muscle Man's devoted girlfriend, means a lot to him—he dislikes being called "Mitch" by anyone except her. Once a competitive bodybuilder, Muscle Man earned his nickname by dominating events at the Power Tower, showcasing surprising strength beneath his relaxed exterior.

Benson's childhood was marked by a verbally abusive environment, which deeply influenced his quick temper and frequent outbursts as an adult. After leaving home, he excelled as a Stick Hockey Master and served as the drummer for the band Hair to the Throne. Unfortunately, despite his talent, he received no recognition and was eventually dismissed from the group.

Later, Benson became the manager of the Park, where he hired Mordecai and Rigby. Their constant slacking often pushes him to his limits, but his determination, athleticism, and unwavering focus help him maintain control and keep the Park running smoothly.

Benson is more than just his fiery temper—he’s proven himself capable in challenging situations, revealing a tough and resilient nature. Despite his strict demeanor, Benson is sociable and just, even rewarding his staff with time off during his rare good moods. Notably, he once appeared on a game show, but after a mishap involving a mispronounced word, he was eliminated and hilariously lost all his hair.

Margaret Smith emerges as one of the show's memorable characters, initially introduced as Mordecai's love interest. Their relationship takes a turn when Margaret leaves for college, driven by her ambition to attend Milton University—a dream she works hard to realize. After graduating with a journalism degree, Margaret embarks on an exciting career as a news reporter, exploring new places across the globe.

Margaret stands out for her kindness, sincerity, and steady presence. She is deeply passionate about both her work and academic pursuits. Throughout the series, she becomes entwined in a love triangle with Mordecai and CJ, but ultimately, she and Mordecai mutually decide to transition from romance to friendship, demonstrating emotional maturity.

As a recurring figure in Regular Show, Margaret significantly influences the storyline, particularly impacting Mordecai's development and personal journey over the course of the series.

Mr. Maellard stands out for his strict, greedy, and eccentric nature. He is quick to blame his employee Benson for problems at the park—often ignoring the true troublemakers, Mordecai and Rigby. His loud outbursts and impatience are a trademark part of his management style.

He rarely shows appreciation for his staff, often calling Benson demeaning names and reserving gratitude for rare moments, typically at the end of an episode. However, underneath his tough exterior, Mr. Maellard reveals genuine care for his adopted son Pops, offering support and guidance as Pops matures.

Mr. Maellard’s quirks shine in episodes like “Maellard’s Package,” where he reacts dramatically—even to minor events like receiving a sandwich. Despite his many flaws, his love for family runs deep, shown by his heartfelt grief for Pops during the Dome’s three-year disappearance and at his son’s funeral.

CJ, also known as Cloudy Jay, is a memorable recurring character in Regular Show. Voiced by Linda Cardellini, she begins as Mordecai's girlfriend; however, their relationship becomes complicated by a love triangle with his ex, Margaret, leading to an eventual breakup.

Easygoing and cool, CJ is an expert at blending wit with charm. She shares Mordecai's love for video games, rock music, and playful antics, often teasing those around her in a fun and lighthearted manner. Her sense of independence makes her truly stand out.

CJ excels at mini-golf, though she initially disliked the game due to her father's overly competitive attitude. This changes after she finally beats him in the episode “Daddy Issues,” overcoming her resentment and gaining confidence.

As a cloud-based being, CJ has the unique ability to transform into a storm cloud, unleashing rain, lightning, and powerful winds when provoked. Although usually friendly, her temper can get the best of her, especially when upset or acting on incomplete information. She is depicted with white skin, billowy cloud-like hair, and typically wears a red-orange and white-striped tank top, brown shorts, and black boots.

The Baby Ducks are a delightful group of four yellow ducklings first discovered by Mordecai and Rigby at the park fountain in the episode "A Bunch of Baby Ducks." After they imprint on the duo, the ducklings instantly form a strong bond, leading Mordecai and Rigby to take responsibility for their care.

Initially, Benson orders Mordecai and Rigby to clean the fountain and remove the ducks. Despite efforts to relocate them to a pet shelter, the duo ends up keeping them, as the shelter refuses. The Baby Ducks later reveal their worth by helping defeat Giant Susan with Mordecai and Rigby.

Throughout later episodes, the Baby Ducks display extraordinary abilities, such as overcoming aggressive geese and merging into a powerful, giant duck-shaped form to protect their friends. Visually, they appear identical: all have bright yellow feathers, orange beaks and feet, and prominent black eyes.

Thomas, whose real name is Nikolai, endured a difficult childhood after being abandoned in Kyiv. He was soon adopted and raised by Russia, who trained him to become a dedicated operative. Later, he was sent to the United States to infiltrate the Park, posing as an intern named Thomas.

Despite being the frequent target of pranks and often mistreated by his peers, Thomas persevered and eventually earned a permanent position at the Park. Throughout this period, he kept his true identity as a Russian spy—sent to claim the Park for Russia—hidden from everyone.

Everything changed when Thomas learned that Russia planned to destroy the Park and harm its inhabitants. Choosing to protect his newfound friends instead of completing his mission, he betrayed Russia and saved the Park. This decision forced him into hiding, where he now lives undercover but occasionally returns to visit his friends in disguise.

Typically laid-back and unflappable, Thomas is known for his awkwardly timed questions, but he shows unwavering loyalty to the Park and considers the crew his closest friends.

Death stands out as a striking character in Regular Show, representing the iconic Grim Reaper tasked with guiding souls to the afterlife. He is frequently portrayed as cruel, ruthless, and even sadistic, seemingly taking pleasure in the more intimidating aspects of his job.

Despite this harsh facade, Death shows unexpectedly noble qualities, such as honoring agreements and expressing genuine affection for his wife and son. His appearance is skeletal and gaunt, with pale greenish-white skin and hollow, haunting eye sockets, emphasizing his undead nature.

Death’s style is unmistakable—he wears British biker gear, sunglasses, a helmet, and carries a knapsack, enhancing his memorable presence. He makes his debut in the episode "Over The Top," originally taking Rigby’s soul but later striking a deal that restores Rigby to life.

While Death’s form and actions can be fearsome, his character reflects the universal symbol of the reaper: a neutral force diligently carrying out his cosmic responsibilities.

The God of Basketball is a larger-than-life character who makes his home on the moon and wields incredible basketball-themed powers. He's depicted as approachable and friendly, connecting easily with the main characters, Mordecai and Rigby, and even offers to mentor them in the ways of basketball.

When Mordecai and Rigby face challenges in learning the game, the God of Basketball steps in and uses his supernatural talents to instantly elevate their skills. He reappears later in the series, generously granting his powers to Skips during a desperate moment to help save The Park.

With his towering height, the God of Basketball is instantly recognizable thanks to his unique head—a basketball with expressive human features, including a mouth, eyes, and nose. Dressed in a number "1" jersey, bright orange shorts, and long white socks, his distinct look complements his legendary status on the court.

Techmo is a standout supporting character in Regular Show, celebrated for his expertise in tackling digital threats and aiding the main characters against computer glitches and high-tech foes. With his striking green skin, bionic eye, robotic arm, and distinctive white hair, Techmo is instantly recognizable, especially with his torn-sleeved black jacket.

He is further defined by his signature samurai sword, tube socks, and penny loafers. Once a fighter in the American War armed with a wooden arm, Techmo later emerges as a skilled Technomancer. He plays a pivotal role in assisting Mordecai, Rigby, and Skips to defeat the menacing Error 220 in "Skips vs. Technology," and joins the fight against villains in both "Exit 9B" and "Regular Show: The Movie."

In the episode "A Skips in Time," Techmo helps the crew capture a timenado, enabling them to rescue the present-day Skips. He makes his final appearance in the series finale, offering a warm welcome to Skips upon his return from space, leaving a lasting impact on fans of the series.

Garrett Bobby Ferguson Sr., also known as G.B.F. or Giant Bearded Face, stands out as a prominent antagonist in Regular Show. He is best recognized as the main adversary of Mordecai and Rigby, making his first appearance in Season 2's episode, "High Score."

During his introduction, Garrett cheats to keep his title as the universe’s top scorer in the arcade game "Broken Bonez." Ultimately, Mordecai and Rigby outwit him, ending his reign. He later returns in the episode "Exit 9B," brought back by his son alongside a coalition of former villains, only to express clear disappointment in his son's revival tactics.

Garrett also makes a short cameo in "Can You Ear Me Now?," where he appears as a resentful witness, giving testimony against Mordecai and Rigby for having destroyed him not once, but twice.

He remains a fan-favorite character thanks to his massive beard and his show-stopping, explosive defeat, securing his place as one of the series’ most iconic villains.

Don is Rigby's younger brother, who makes his entrance at the park when Pops' quirky attempt to pay taxes with lollipops leads to a tax audit crisis. Mordecai suggests bringing Don onboard, knowing his accounting skills could help resolve the situation.

Rigby, however, is less than thrilled. He's always felt overshadowed by Don, a feeling rooted in childhood moments—like when Don inadvertently stole the spotlight at Rigby's own sixth birthday. Don's easygoing nature and charm immediately win over everyone at the park, further highlighting Rigby’s insecurities.

These feelings of resentment eventually boil over, causing Don to leave in frustration. But when the audit spirals out of control and the park faces possible destruction, Rigby and Mordecai understand they truly need Don’s help. This sparks a heartfelt reconciliation.

Don’s financial expertise saves the day: he completes the audit, restoring everything to normal. Before heading off, he leaves everyone laughing with his signature line, "an accountant's work is never done," ensuring his presence is fondly remembered.

The Halloween Wizard stands out as a menacing and deeply disturbed figure in Regular Show. Exhibiting intensely antisocial behavior, he secludes himself in a spooky mansion with only his cat for company, purposefully shunning any form of social contact.

Driven by a vengeful streak, he delights in delivering ruthless punishment to anyone who angers him. His sadistic personality is illustrated by the cruel and inventive punishments he inflicts on the main cast, most notably when he transforms Rigby into a house and exacts frightful revenge on his friends.

Ultimately, the Halloween Wizard embodies the essence of a classic villain—terrifying, unpredictable, and reveling in mayhem. Although he plays a minor recurring role, his most memorable and sinister appearance is in the episode "Terror Tales of the Park."

The Guardians of Eternal Youth are a memorable group of five cherubic babies with unexpectedly deep voices and the astounding power to grant eternal youth. These unique beings are highly respected by Skips, who was rewarded with his own ageless existence after he defeated Klorgbane with their assistance.

The Guardians made their first appearance production-wise in the episode "Free Cake," though their story chronologically begins in "Skips' Story." They once sent Mordecai, Rigby, and Skips on an adventurous quest to Synthos, aiming to help restore Gary's physical form.

Instrumental in the defeat of Anti-Pops during "An Epic Regular Final Battle," the Guardians are instantly recognizable by their golden hats, brown bibs, and classic white diapers, as well as their resonant, grown-up voices. An interesting detail: Reginald was seen donning black clothing embellished with Magical Elements in "Skips Strikes." In their younger years, the Guardians preferred brown suits, black ties, and the timeless white poet shirts.

Stef is an anthropomorphic batwoman who is Mordecai's wife and the mother of their three children. She made her debut in the series finale episode "A Regular Epic Final Battle". Stef is an artist and her relationship with Mordecai was likely influenced by their shared talent and love for art.

In the "25 years later" comic, it is shown that she is friendly and sociable as she is seen chatting with Eileen during the park reunion. However, Stef is visibly jealous and annoyed when she meets Margaret, who retains her youth and is unaware of her, indicating that she does not like having secrets kept from her.

Not much is known about Stef's history as she does not have any speaking lines in the series finale.

Her personality is tough-as-nails, and she is willing to fight for her boyfriend but can also be an antagonist. However, she is often seen helping somebody out and is on good terms with Mordecai despite their past.

Muscle Dad Sorenstein is the deceased father of Muscle Man. He pretended to be a trucker, but in reality, he was a forklift operator. He loved to prank people, even his son and died after being mauled for putting a cactus under a cop in a bear costume who turned out to be a real bear.

He returned as a ghost to make amends with his son and left behind letters for him. Muscle Dad had a white undershirt, blue jeans, a brown belt with a gold buckle, black overalls with silver connectors, brown cowboy-like boots, and a trucker net hat that said "World's Greatest Trucker".

When he became a ghost, the words on his hat changed to "World's Greatest Forklift Driver".

Low Five Ghost is a character who looks identical to High Five Ghost but has facial hair, teal sunglasses, and two hands out more than his counterpart.

In "Men in Uniform'', it is revealed that he has been stalking and plotting revenge against Pops for the last 4 years. He attacks Pops but gets stuck between dimensions due to his large head, which eventually becomes a beneficial attraction for the park.

The character is voiced by Vanessa Marshall, and she is a part of Rawls' personnel in the show.

Colonel Rawls is a recurring character. He is the commanding officer of the Space Tree Station and works alongside Chance Sureshot, Toothpick Sally, and Recap Robot.

However, he is also brave and selfless, willing to risk his own life to save others.

Langer is seen mostly in a lab coat and jet-pack, sporting an eye patch on his left eye. He led the scientists' experiments through the park and spearheaded many rules, much to the annoyance of the park workers.

After testing the park employees for some time, they were launched into space because of Pops' true origin and Anti-Pops' quick movement.

Archie the Archivist appears in multiple episodes. In "The Last Laserdisc Player," he helps Mordecai, Rigby, Muscle Man, and High Five Ghost retrieve a laserdisc player, and he transforms into the Laserdisc Guardian to protect it.

In "Format Wars II," he learns that his long-lost son, DVD, is leading an attack against obsolete formats, including laser discs. With the help of his son and friends, Archie prepares to battle DVD and his minions but ultimately reconciles with his son, who was seeking revenge against him for unknown reasons.

Archie later dies at the hands of the Internet, a former ally of DVD. In the end, Archie appears as a ghost and watches a movie with his son and friends, unaware that the Internet is still plotting against them.

Celia is a minor character who appears in the episode “The Postcard” for the first time. She is a human teenager who is in high school. In fact, she moved away to Prague to pursue her studies.
 
What makes her character memorable is the fact that she is the girlfriend of Hi-Five Ghost. The both of them dated briefly and agreed to meet again in the future if she was still single. Both Celia and Hi-Five Ghost are similar in their likes and character traits.
 
She was described as a feminine human version of him. In the season finale, we see that Hi-Five Ghost and Celia have married each other and have a child.
 

Quintin “Quips” Quippenger is Yeti and Skips’ cousin. He debuts late in the series during the fourth season and appears only for a short while. Quips is known to be the annoying cousin who bugs everybody with his bad jokes.
 
Quips is a nice guy, despite his bad jokes and socially insensitive behaviour. He is actually too innocent to understand his faux pas, which makes it more annoying. Everybody at the park wants him gone, except for his cousin, Skips, who likes him.
 
Quips appears to have no friends and depends on Skips for socialising. Yet he is happily engaged to his loving fiance, whom he later marries.
