Randall "Randy" Boggs is one of the main antagonists of Disney•Pixar's 2001 animated film Monsters, Inc. Snide and vindictive, Randall is notoriously envious of James P. Sullivan, the most beloved scarer in Monstropolis. To make his mark on the world while simultaneously stealing Sullivan's spotlight, Randall plots to "revolutionize" the scaring industry using conspiratorial means that involves abducting human children.

In Monsters University, Randall was a kind, timid teenage monster who would hang out with Mike, as they were initially roommates. He admired Mike's confidence and was originally discouraged of his camouflage ability, thinking it would make him a joke until Mike complimented his ability, saying he had to use it. Though Mike's suggestion of not using his glasses to become completely invisible led to Randall's constant squint.

Randall expressed a desire to get in with the popular crowd and quickly turned his back on Mike when he was invited to join Roar Omega Roar, even participating in a prank on Oozma Kappa.

After his blundered performance at the end of the Scare Games (which presumably got him kicked out of the RORs), Randall gained an enmity towards Sulley, vowing it would be the last time he ever lost to him.

In Monsters, Inc., Randall is greedy, ruthless, sneaky, short-tempered, competitive, and overall evil in nature. As well, Randall is something of a selfish jerk who doesn't care about a lot of people. Judging by his intentions to capture children for their screams (and possibly never return them), he is probably willing to severely harm little children (or worse). He is so sneaky that he eventually teamed up with Mr. Waternoose, working as his partner-in-crime in the plot and convinced him it was to benefit the company, to which Waternoose is later exposed and arrested. Randall was also shown to be murderous towards Sulley, as he once whacked him very hard with a scream canister during their fight in the secret compartment of the company while gloating that he had wanted to do that for a presumed long time beforehand. He then tried to strangle Sulley to death by wrapping himself around his neck, and would have succeeded had Mike not accidentally hit Randall with his remaining snow cone.

Randall has no concept of forgiveness and compassion, as stated by Sulley in Kingdom Hearts III as he only cares about himself and winning and has no comprehension of friendship. He has no respect for anyone, not even Mr. Waternoose. However he is grateful for Johnny Worthington III saving him from the Cajun family, even saying he owned him a favor, but showed no disrespect towards him due to getting kicked out of ROR after losing the Scare Games during college.

In Monsters University, Randall is seen as a young, freckle-faced teenager. He sometimes wears his purple glasses, but stops wearing them near the end of the film for more advantage to his invisibility (as well as led to his constant squint).

In Monsters, Inc., Randall has three fronds with pink tips, purple skin, green eyes, four arms and four legs (three toes and three fingers on each of his limbs), a sky blue tail, and has the ability to completely blend in with his surroundings, making him invisible (as well as being able to cling to walls). He can also camouflage similar to the way chameleons are misconceived to.

In Monsters at Work, Randall is mostly unchanged as his same appearance, but he now has a scar over his right eye due to being frantically hit with a shovel by the woman in the trailer, and a brighter color scheme.

Randall Boggs is a chameleon/gecko-like monster. He is shown to be able to climb on any terrain such as walls, using his feet and hands to grip on the surface. He can even stay on a vertical wall facing downwards without problems. Randall signature ability is to change his skin color to blend into any environment and can camouflage the people who are in contact with him. He can use this in hand-to-hand combat which is how he overpowered Sulley. His invisibility/camouflage does have limits as when he was in school, he couldn’t camouflage his clothes like his glasses.

In Monsters, Inc., Randall is Sulley and Mike's arch-nemesis and direct rival. He is able to harness his invisibility at will, even when using the element of surprise, as seen when he used it to scare Mike in the locker room. Mike denied he was scared (which Randall doubts) while Sulley tells Randall to save it for the scare floor which Randall says he's planning on getting some big numbers. He is shown to be in competition with Sulley and Mike for the glorious post of Top Scarer. He also managed to beat Sulley and become the Top Scarer, though the victory was very brief as Sulley managed to scare an entire slumber party and regain his spot seconds later. He then furiously threatens to put Fungus into the shredder if he does not bring him a new door in five seconds. However, Randall has also constructed a "scream extractor" and tries to abduct a human child in cooperation with the company's leader (and his own henchman) Henry J. Waternoose III, with the hope of eventually rising to the leadership of the company.

However, this plot failed when Sulley was sent by Mike after closing hours to recover paperwork (which Mike forgot to turn in) and stumbled upon the kid, whom Sulley nicknamed Boo. Upon hearing about Boo on the news, Randall spends the entire night looking for her. He eventually deduced from a newspaper that Mike (who is quick to point out that Boo only escaped because of his moonlighting) was involved in Boo's release into the Monster World and tried to talk him into bringing the child to him, only for this to backfire when Mike accidentally got himself captured trying to convince Sulley that Randall was not up to something.

Largely because Sulley witnessed Randall going in, they initially thought he was trying to "cheat" at the scare record. However, after his accidental capture of Mike, he makes clear that his plans did not even involve winning the scare record, let alone cheating at it. After Sulley and Mike are exiled, Randall and Mr. Waternoose go through with testing the Scream Extractor on Boo. However, Mr. Waternoose expresses distaste and guilt for having to exile Sulley and Mike due to Randall's negligence, as well as pointing out that Sulley was "twice the scarer Randall could ever be." after Randall claimed that "Sullivan got what deserved.", much to his annoyance. After Sulley manages to escape and wreck the Scream Extractor, Mr. Waternoose orders an enraged Randall to stop him as Randall then attacks Sulley and tries to strangle him. He proves to be quite an adversary due to his chameleon-like abilities. However, when Mike gets annoyed with the fact that Sulley is not listening to his apology, he throws a snowball at him, hitting Randall instead, allowing Mike to realize that Randall has been attacking Sulley.

Randall gave pursuit and had them cornered at the Scare Floor. After learning the truth from Mike, Celia aided them by "awarding" Randall with the all-time Scare Record (though Randall was too determined to stop Sulley and Mike to care about his "victory"). He goes after the trio in a chase through the factory until he manages to grab Boo and escape into an activated door. When Sulley comes to rescue her, Randall surprises him and tries to send him falling from the door, lamenting of how Sulley was always the best Scarer and with him gone, Randall will finally come on top. Suddenly, Boo overcomes her fear of Randall as she begins to pull on his frond and hits him with a baseball bat, making him turn different colors, then Sulley restrains him with a chokehold, followed by a snake wrestling maneuver. Sulley remarks to Randall that it looks like he is out of a job.

Afterward, he gets thrown through an active door while desperately begging them not to do it, therefore banishing him to a trailer home in the middle of a swamp in the south, where a Cajun family beats Randall senseless with a shovel, thinking he is an alligator. Sulley then shatters the glass light on the door with his fist and is then tipped over the railing it was leaning against and shatters on the floor far below, thus ensuring Randall can never return through it.

Randall's plan is further foiled when Sulley and Mike later expose Mr. Waternoose of his and Randall's actions in front of the CDA, resulting in the former's arrest.

In the prequel, Randall (nicknamed "Randy") is first seen when Mike arrives in his new room as Randall is his roommate. The two greet each other and Randall seems nice, offering Mike first choice of the beds. Randall shows he has the power to turn invisible, doing so when surprised, leaving only his glasses hovering in mid-air. Mike suggests that he should use that power when scaring, to Randall's surprise. He soon follows Mike's advice of getting rid of his glasses because they don't disappear whenever he turns invisible. Even though the two become great friends, Randall is worried about school and wonders if he'll manage to impress the cool kids, but Mike reassures him. He follows Mike and sits next to him on their first day of class.

Later, while Mike is studying scaring, Randall decided to bake cupcakes for a party organized by the cool kids, decorating them to spell "Be My Pal" (the letters on Randall's cupcakes are replaced by smiley faces in the international versions of the film to which the smiley faces are likely to represent Randall being a grateful colleague to Mike). At the party, Randall tries to offer cupcakes to some girls, but Mike runs into him while riding Archie the Scare Pig, splattering all the cupcakes on Randall, which spell "lame," with the letters on them, much to his dismay (the international versions of the film, the cupcakes spelling "lame" have been altered with smiley faces).

He is later seen helping Mike study by asking him questions on phobias (such as arachnophobia, fear of spiders). However, Randall ends up slowly decreasing his friendship with Mike when he replaces Sulley as a member of Roar Omega Roar and thus was unable to help Mike and join Oozma Kappa as their sixth member since he is finally in with the "cool kids". His friendship with Mike decreased further when Randall took part in his group's prank on Mike's team, Oozma Kappa.

After this, he is frequently seen in group shots of Roar Omega Roar until the final event of the scare games, where he faces off against Sulley. Randall is poised to scare, when the vibrations from Sulley's roar, cause him to fall on a carpet and involuntarily blend in with its pink and heart pattern, causing his scare score to be minimal, resulting in his former "friends" berating him and kicking him out. After this, he looks over bitterly at Sulley and utters his last line in the film "That's the last time I lose to you, Sullivan."

Because of this, Randall supposedly begins his gradual descent into villainy as his jealousy for Sulley grows over the years. Because of his hatred for Sulley, he also comes to no longer accept Mike as well, but not for the same reason. Randall seems to hate Mike by the time Monsters, Inc. happens, not because of anything that he personally did to him, like Sulley, but simply because of Mike's close association with him.

During the credits, Randall appears on one of the scare cards, eventually becoming a scarer at Monsters, Inc.

Randall returns in the season two finale of Monsters at Work as one of the main antagonists. He was rescued by his old ROR teammate Johnny Worthington III and brought back to the monster world shortly after being banished in the human world by Mike and Sulley. Together, they stole laugh energy from Monsters, Inc. and passed it off as their own scream power for Fear Co. He even rewired the empty canisters to give false readings, so no one would notice the missing laugh energy. He also stole Mike's lucky mitt, sugar packets, and Boo's drawing and vandalized the laugh floor with paint from the hardware store owned by Tylor Tuskmon's family and planted the stuff in Tylor’s locker to frame him for the crimes.

After Johnny and Randall's arrest, Randall escapes custody and remains on the run.

Randall and other monsters appear on a poster at the Baseball field in Meet the Robinsons.

Randall is included as a playable character in Disney Infinity and its subsequent 2.0 and 3.0 editions, playable in the Monsters University playset and the Toy Box Mode of all games.

Randall made his debut in the third numbered installment of the Kingdom Hearts series, as an antagonist in his homeworld "Monstropolis". Having been freed from his banishment by Vanitas who plots to use his ambition and desire for revenge, he reconstructed the trailer door and gives command over the Unversed to collect negative emotions. Randall plans on using his new friends to take over Monster's Inc. and get revenge on Mike and Sulley.

Randall is first seen invisibly watching Sora, Donald, Goofy, Mike, Sulley, and Boo head into the Door Vault and decides to follow them. Later, he disguises himself as Boo's door luring them into the booby-trapped basement of the factory, where he tells them how a "really nice man" saved him from "becoming someone's handbag", only to receive a rude rebuke from Mike. From here, he gloats to the heroes on his return and impending success, then vanishes as he waves away Sora's defiance.

After the heroes traversed through the factory, Randall accosts the group as they are leaving the factory floor and attempts to sic one of his machines on them. However, he storms off when it is unresponsive to his commands, only to spot Vanitas animating it as the Lump of Horror just after the heroes leave.

Pleased, he takes the Unversed to the Door Vault to confront the heroes. Delighted by Mike's ignorant dismissal of the threat, Randall gloats as the group is attacked by the massive Unversed. However, after the heroes defeat the Unversed, Randall is sent back through his banishment door, where he gets beaten up by the Cajun family again. Before Sulley can destroy the door, Sora decides to use his Keyblade to lock the door, causing it to disappear and preventing Randall from coming back to Monstropolis, thus yet again, ensuring Randall cannot return through the door once more.

Randall Boggs appears in-game during the game's patch update along with Captain Hook. Randall can use his invisibility to hide from enemies and uses an attack that dodges everything and hits the enemy with his hands, also when he revives, his skin changes similar color when Boo hit him when he changed color. Randall's attacks scare enemies, additionally with his Purple Skill unlocked, he deals bonus damage to scared enemies. Randall enters each fight invincible for a first few seconds.

Randall has friendship campaigns with Yzma and Gaston. He also has friendship campaigns with Shan Yu, Oogie Boogie, and Basil of Baker Street.

Randall, as a main antagonist, eventually found his way back to Monstropolis using the door system and survived his encounter with the hillbillies. As part of his revenge against Mike and Sulley, he tried to frame Mike for stealing the other monsters' comedy props. After Mike has been sent to prison, Randall strikes again trying to frame Sulley for assault on Waxford when he visits him in the security camera room to look at the tapes of the locker room. The fight makes its way to the Laugh Floor where after being unable to hit Randall, Sulley succeeds in exposing him by pulling the fire alarm. Randall is sent to monster prison afterward and Mike's name is cleared. Later, Randall would be freed by Sid Phillips (who had visited the Monster World earlier) alongside Mr. Waternoose and the three would together work on another revenge plot. They cut off the door power when Mike and Sulley return from a visit to Boo's and try to figure out how to go about their revenge. Randall turns down Waternoose's idea of a frame job and Sid just wants his reward of being given the door system patents to become rich in the human world. Eventually, Celia and Boo escape when Boo activates her door and the three villains give chase while shutting Mike and Sulley out of it. Going to the neighbor's house, all three try to capture them, but Celia and Boo make it to the resident child's closet and bring the three right to a CDA task force waiting to take them into custody. It is likely that Randall was arrested again and was not released along with Waternoose.

Above Randall's bed in Monsters University is a framed inspirational poster with the words "The Winds of Change: Can you hear them?" printed. This is a reference to his infamous quote from the first film.

Randall serves as the host of the PC game "Pinball Panic", which came as a bonus disc with select copies of the Monsters, Inc. 2-disc Collector's Edition DVD.

In international releases of Monsters University, Randall's cupcakes have smiley faces on them. This was to get over the language barrier (although the cupcakes have smiley faces on them on releases in English speaking language countries).

Randall is the only antagonist from a Pixar film seen in the Kingdom Hearts series.

Randall is partially named after Randy Newman, who composed the soundtrack for Monsters, Inc.

According to Randall's scare card, Randall is 5'0" ft. tall, weighs around 220lbs, and was born on March 26.

After being brutally beaten with the shovel by the woman in the trailer, Randall suffers a scar on his right eye in Monsters at Work.

Randall's strong jealousy towards Sulley for being the Top Scarer is made even more appropriate by his appearance; in other words, he's a green-eyed monster.
