Marcy is close friends Anne and Sasha and serves as the brains of the trio, is an expert gamer, and has many clumsy moments which that Anne and Sasha have to counter. She learned of a mysterious chest located in some store that she, Anne, and Sasha stole it from and was alongside them when Anne opens it which sends her, Sasha, and herself to Amphibia. Upon arrival in Amphibia and being found by the inhabitants of Newtopia, Marcy serves Andrias as his close aide and chief ranger of the Newtopian Knight Guard. Unaware that he is secretly plotting a mysterious agenda involving her and her friends.
Marcy is an intelligent young female, and is often seen researching things and taking notes. She is curious and takes interest in culture, being the one who discovered the Calamity Box. She is also cunning and resourceful.
She is very clumsy, but she generally remains forgetful and unbothered by it. Back on earth Marcy was somewhat dependent on her friends, as she constantly relied on Anne to look out for her, and was used to having Sasha make decisions for her. Ever since she came to Amphibia, however, she has learned to take care of herself better, and make her own decisions without many people's influence.
She loves video games, research and puzzles. Marcy is also a highly energetic person, and gets easily excited about anything that interests her. Even things such as seeds, history, and other things girls her age normally wouldn't be interested in will cause her to talk nonstop. When she gets too into something. While people like Rosemary, Lavender and Ginger would view her as a weirdo because of her unusual interests, this would lead to her becoming friends with Maddie Flour, as well as training as Maddie's apprentice in the magical arts.
She is an Asian teenage girl with a tall slim body, short black hair with a green barrette on the side of her head.
On earth, she wears a gray hooded school uniform, a green skirt, pale blue socks, and brown shoes.
In Amphibia, Marcy wears a faded grey hooded cape, complete with a white-furred collar which is held together with a light shell. She also wears a brown metal chest plate, a stitched skirt, and grey winter snow boots which are wrapped with studded straps. Marcy has gray finger-less gloves on each of her hands, moreover, her signature primary weapon seems to be a golden hand-mounted crossbow that is fitted onto her right forearm and glove.

Role in the series
Back on earth Marcy hanged out with her two friends Anne and Sasha all the time. She was a top student, but was so clumsy Anne had constantly to look out for her, also she was used to having Sasha coming up with what to do. On Anne's 13th birthday she sent a picture of a mysterious music box to Sasha; the 3 friends decided meet at the thrift shop. Once Sasha coerced Anne into stealing the box the 3 friends went to a park to examine it. As soon the box opened, the human girls were transported to the world of Amphibia but were separated. The part of Amphibia Marcy was sent to was the capital Newtopia were she met King Andrias who convinced her to let him help her find away home. After doing some work for the newts, she eventually became the chief ranger of the Newtopian knight guard.
Marcy only appeared in photos and a non-speaking role in a flashback and was mentioned a few times.
During the Barbari-Ant Invasion, she was happily reunited with Anne when she came to Newtopia in hopes of finding a way home. After hugging (and putting out Marcy's cape that somehow caught fire), Anne introduced her to the Plantars. Marcy then excitedly introduces herself to the family, as she even deduces that they're from Frog Valley judging from Hop Pop's skull cranium and soil attached to him, witch amazed Hop Pop at and easily won him over by complimenting Hop Pop on his status as a farmer. Then Marcy begins to examine Polly, as she points out to her that her legs will likely grow out of her in two months witch exited Polly and won her over. Marcy then introduces herself to Sprig, but Sprig instead greets her with a skepticism, because of his discontent with trusting Marcy due to his family's previous battle against Sasha and her toad army. When Anne asks about where she's been, Marcy informs her that she had actually warped right inside the city of Newtopia, where she managed to become well acquainted with them after realizing the newts were similar to a race known as "sephilons" she learned about while playing a video game known as Creatures and Caverns.
Anne asks Marcy for a way inside Newtopia, but unfortunately she can't let them in until the ants are dealt with, but luckily she has a plan and leads them away. At a nearby tent, Marcy enters the tent and introduces the newts to Anne and the Plantars. While the newts admit they haven't agreed yet on a specific plan, Marcy assures them she has a plan of her own. She then proceeds to state the plan, which is to sneak into the hills of the ants and drive the queen away from their lair to force the rest of them to retreat with her. When Sprig questions how they'll manage to pull that off, Marcy shows everyone a belt equipped with stinkshrooms, that will let out toxic pheromones which are capable of driving the ants away. Anne then begins to point out the dangers of the mission, especially when knowing they'll inevitably have to fight through some of the colony to get to the queen. This leads Anne to suggesting she and the Plantars take care of the mission instead due to her experiences in dealing with stuff like this in Frog Valley and was well aware of Marcy's clumsiness, but Marcy assures Anne that she'll be fine (Just as Anne points out her burning cape again). Marcy, Anne and the Planter's then enter the Barbari-Ant colony were they are ambushed. Ignoring Anne telling to stay behind them Marcy notices a plant and begins analyzing it, mixing it with chemicals in a beaker of which she had brought with her; this creates an explosive formula, allowing everyone to escape when Marcy throws it and blowing a hole in the wall. Once through, Marcy throws an insta-vine potion which automatically begins growing vines in front of the wall to keep any more ants from chasing after them. Unbeknownst to her, Marcy had accidentally trapped Polly on the other side after realizing she never made it through the hole, causing everyone to rip apart the vines to let her through. Luckily Marcy manages to throw another insta-vine potion at the wall just before the ants arrive again. They finally reach the queen in the egg chamber were they start planting stinkshooms, with Marcy telling them that they would start releasing their pheromones 5 minutes after they are planted so they would need to work quickly. As everyone begins getting to work, Anne soon pushes Marcy out of the way from a nearby falling rock, as they manage to stay out of sight from the queen by hiding behind the rock itself. Marcy then states she was about to move out of the way on her own, but Anne disagrees, believing she needs to make sure Marcy stays out of danger just like back home. Marcy reminds Anne that they're not back home right now, and she's managed to take care of herself up until now. It was then Spig lets out a scream after a nearby egg hatches and the larva lunges towards his face, causing him to alert the queen. The Queen then lunges at Sprig and eats him whole, before screeching and calling even more ants to arrive. Marcy then points out that Sprig is still alive since ants take longer periods of time to digest their food, as she then proceeds to go save him but Anne stops her once more. Anne asks her to stay put and that she could save Sprig instead, but Marcy reminds her that she's the most knowledgeable with Barbari-Ant biology and therefore most fit for the job, but Anne continues to be persistent while believing she can still do it in her place. Marcy then demands to know why she won't let her do it, to which Anne then tearfully admits she had just got her back, and she doesn't want to lose her again. Marcy then promises Anne she can do it, as she proceeds to bounce her way towards the queen on the ants' backs, knowing they have bouncy bodies from her research. Once Marcy is also eaten by the queen, she manages to make her throw up both her and Sprig, with Marcy now having gained Sprig's trust. Marcy then shoots an arrow at a nearby rock to swing them safely to the ground, but the queen instantly slices the rope, causing them to crash to the ground as they're once again surrounded by the ants. It was then the stinkshrooms begin to go off in the nick of time, causing the queen and the rest of the ants to flee from the group as they tunnel away from Newtopian grounds.
As they group leaves Marcy thanks Anne for having her back, but Anne is now convinced she really has changed (Then Hop Pop and Polly point out that once again her cape's on fire). Once the group is out of the cave, Sprig apologizes to Marcy for his prior suspicions of her, with Marcy just being glad he's okay since she could tell that he means a lot to Anne and the two start to bond. The gates of Newtopia are finally open again as Marcy shows Anne and the Planters in. After reporting to Lady Olivia that the mission was a success and introduces her to Anne and the Planter's. Marcy has a word alone with Anne and then suggests they go find Sasha, but Anne informs her that she already had, only they had fight with swords and explosions and now she's unsure of her current location. Marcy states that even if they found a way home, it would all be for nothing if Sasha wasn't with them, as she also admits she's unsure of what to do since Sasha was always the one who came up with the decisions.
Anne then suggests they should now begin making their own decisions, with her and Marcy agreeing with her because it has works out so for them. Both then declared to each other that together they'll find Sasha and find a way home. Anne the proceed to tell Marcy everting that happen to her since coming to Amphibia.
Marcy took her friends to a burger joint where she counited to impress the Planters with how smart she is while Anne shows how silly she is. They then receive a note from the king via an arrow. Rather than giving a direct message gave them a scavenger hunt were when all the clues are gathered it reveal a hidden message. As Marcy uncovered the first 2 clues Anne feels more and more insecure about her own intelligence. After escaping a sewer gator Sprig accidently reveals that Anne is jealous about how smart she is, Marcy reveals that she is jealous of Anne because how social she can be. Anne then discovers the third and final clue; the full message reads "Bring Me The Plantars".
Marcy brings Anne and the Planters before Andrias Leviathan, king of Amphibia. When Anne showed a picture of the music box Andrias notices that the gems are gray rather than colored like they were pervious. In order to learn more of the box and find the way home, Marcy must do some research in the archives. During her research with King Andrias she accidentally spills coffee on a tapestry, but discovers a button that opens a secret passage leading to a secret wing of the archives that had vital information.
The night before King Andrias would tell what their research uncovered, Marcy decides to have a sleepover with Anne, Sprig and Polly. Anne and Marcy realize that they never had a sleepover without Sasha as she is the "Queen of Sleepovers", but know that they have had enough experience to throw one for Sprig and Polly. They declare the sleepover mantra "Pajamas, junk food and gossip galore, pillow fights, movies and tearing up the dance floor and listen up cus' this I won't repeat; never ever go to sleep". They all proceed to run amok throughout the castle; upsetting Lady Olivia who tells them to never go into the basement. As the gang relax, they realize that it is only 9:00 pm and Anne insists that they do a Scare Dare Challenge with the loser's name going into the Book of Losers forever. Against Lady Olivia's warning, Anne suggests they head down into the basement. The kids sneak passed Lady Olivia, whom Polly draws on, and head down with them all refusing to turn back, lest their name end up in the Book of Losers. They enter hallway full of mirrors and find a blocked doorway with a sign in ancient Newtonian runes saying that everyone correctly assumes that it saying something like "Keep Out". They break it open anyway and find themselves in a flooded room full of coffins. Anne and Marcy try to prove their bravery by going to one of the coffins and taking a selfie, upon which jellyfish/ghost-like creatures emerge. They immediately deduce that they are deadly and flee the coffin room together. Along the way, Marcy notices a room full of growing plants that do not need sunlight and Sprig takes note of a destroyed painting of what looks like King Andrias with 2 other individuals; a frog and a toad. The gang find a trap door that immediately enters Marcy's room, much to Marcy's surprise and confusion, but the ghosts phase in anyway. They quickly discover that holding a mirror up to them makes them solid and push them back into the basement. The kids refuse to go to sleep and stay awake until morning. After wondering so many questions, they agree that the sleepover was great and all four of them add their names to the book. Anne and Marcy reveal that they have added their names numerous times and that Sasha always won. When Anne states that she needs to make up with Sasha, Marcy comforts her and assures they will find her. Lady Olivia angrily enters to tell them that their meeting with King Andrias is soon.
The human girls and the Planters arrive in the throne room were King Andrias showed them a book that tells them that the 3 gems on the music box need to be recharged. In order to do that, one must go to three separate temples to have each gem charged up, but the book only gives information on one of them. Hop Pop wants to get back to Wartwood as soon as possible so as not to miss the annual harvest. Anne suggests going back to pick up the music box and and meet back up with Marcy at the first temple. However, Marcy suggests that Anne stay with her in Newtopia as them separating is the last thing they should do. Anne and the Plantars are visibly saddened by this logic and Marcy suggests that they spend the day to themselves before they leave. The next morning, Anne says goodbye to the Plantars as they head back to Wartwood. Seeing how sad Anne is, Marcy admits that sending a servant to retrieve the music box might not be a good idea and that someone trusted should go. Anne hugs her and runs of to meet with her surrogate frog family. Once Anne has left King Andrias comes up to Marcy with a proposition he believes would be very interesting to her.
Marcy arrives on her avian transport Joe Sparrow who announces that she has information on the first temple they must venture to recharge the first of the box’s gem (While temporally get distracted on how “rustic and cute” the Planter farm is). She explains that the temple is full of deadly traps and that no one has been able to surpass them. This actually excites Marcy, but Anne tells her that she has a habit of getting "lost in the zone" and tunes out everything else, much to her safety. Marcy brushes this aside as they arrive at the temple, via her sparrow steed. The group end up in a large cube shaped room where Anne discovers what looks like a puzzle cube. Upon holding it, the barer gets encompassed in a magnetic bubble. She gives the box to Marcy who uses it to solve the puzzle. However, whenever she messes with it, it causes the room to turn and alter, harming Anne and the Plantars. Marcy manages to solve it and the door opens up with Marcy excitedly rushing into the next room and disregarding her friends' wellbeing. The next room has a floor of colored tiles. The group quickly learn that the pink tiles are fire traps and blue tiles are spike traps. The green tiles are safe, but there is only two of them. Marcy jumps onto one and beckons someone else to hop on the other. Anne and Hop Pop both calmly argue with one another about who should jump on the green tile. While Hop Pop claims he should do it to redeem harming Anne, Anne feels she should do it as Hop Pop has suffered enough. Anne forcibly does so and manages to land on the tile, opening the door to the next room. Anne and Hop Pop continue arguing up until the next room which contains a chess-like game called flip wart. Marcy just so happens to be an expert at the game, but upon setting up the pieces, Polly falls through the floor and ends up as the actual flip wart piece on a bigger board. Realizing that they are to be the actual pieces, Sprig and Hop Pop are also transferred to the big board while Anne is transferred to the opposing side, much to everyone's shock. Marcy uses her skills to try and avoid harming her friends, but the game cheats and Anne ends up harming Hop Pop. As Anne unwillingly chases Hop Pop across the board, Anne finally breaks down. She is not mad at Hop Pop anymore, but wants to have time to herself. Hop Pop understands telling her to take as much time as she needs. Realizing that she has put her friends in danger, Marcy tries to forfeit and rushes the board before using Sprig as a projectile and destroying her own piece, ending the game. Marcy believes that she has lost her chance at recharging the gem. The temple leads them out with glowing green arrows. However, the group discover that the arrows are leading them to the outhouse. It turns out that the outhouse is actually the recharging station and that Marcy learning humility was the test. Marcy places the gem on the pedestal and the green energy is recharged into it (With the green also draining from Marcy's eyes). The gem proceeds to point them in the next direction as the group plan to take a break for the time being before heading to their destination.
Marcy is excited to be living among the citizens of Wartwood and get firsthand experience being among farming natives. However the townsfolk, in their usual manner, do not take kindly to Marcy's appearance, leaving her feeling dejected. Anne comes to comfort her and tries to explain that it takes time for people to accept outsiders in Wartwood. Marcy believes that she needs "strategy" to get the people to accept her, but in her epiphany ends up knocking over the statue of the town's founder. The townsfolk are angry, but Marcy uses her science skills to fix and clean the statue, much to everyone's astonishment. Marcy decides to use her ways to improve the town, having done so with Newtopia. Anne shows Marcy all the problems with the town such as potholes, out of date street lamps and broken fences. Despite all of this, the townsfolk still do not like Marcy all that much. When she wishes to do something bigger, Mayor Toadstool approaches her with numerous plans that he has to make the town look better. Anne prevents Marcy from taking any of them as she knows that Toadstool's plans tend to go awry. However in the middle of the night, Marcy, too excited to sleep, decides to take up Toadstool's plans to expand the town's appearance. The town looks brighter and cleaner, though a lot of it is just coatings over the preexisting buildings as the Wartwood enjoys its appearance.
Suddenly, the ground begins to give way as Wartwood was built over a swamp and the weight of the additions is causing it to sink. Anne once again tells Marcy that she should have been patient with the people and she calls upon Joe Sparrow to take all the unnecessary buildings and toss them away. The town rises and the citizens criticize Marcy for her careless actions. However, they add that she acted impulsively just like Anne did when she first arrived and tell her that one day they will approve of her, much to her delight. Marcy then proceeds to rapidly rebuild all the buildings with Anne claiming she is indeed on a level of her own.
After shopping for seeds with Hop Pop she was struck with amazement when she gazed upon Frobo a mysterious robot that was befriended and named by Polly. After the Planters took the robotic frog in she began to examine him.
Marcy, who was researching the flora and fauna, sees Maddie restore the tree to its former glory and scolds her sisters Rosemary, Lavender and Ginger for their upheaval. Marcy introduces herself after they depart and shows an interest in learning spells as well. Maddie is enthralled by Marcy's passion, and the two head out to collect charms, much to the tadpoles' displeasure. Maddie tells Marcy that she used to play with her siblings all the time before she found her interest for magic and now has little time to play for them. Marcy advises her to allow time, but Maddie considers her work to be more significant. While Marcy bonds with Maddie, Rosemary, Lavender, and Ginger become jealous of her and decide that they need to be older in order for Maddie to play with them again. They steal her spell book and cast a spell in the morning, but Maddie chastises them for scribbling in her book. Despite this, the tadpoles feel they have finished the spell they need to use. Maddie and Marcy are successful in resurrecting Fleafy, but their triumph is short-lived due to the arrival of Rosemary, Lavender, and Ginger, who have risen to be giants. The three ends up causing mayhem all over town. Maddie realizes that they haven't mastered the growth spell and that they made their decision based on her advice to "grow up." Maddie, now that she realizes she's to blame for the crisis, has Marcy work on a cure as she grows to giant proportions to settle them down after they learn they can't stop rising. Maddie juggles her sisters as Marcy administers the cure to them. Maddie then apologizes to her sisters for not being a proper sister, taking Marcy's advice.
When they came to the second temple, they encountered Valeriana who was part of an ancient order, whose purpose was to study the gems and the box itself. After Anne completed the trials, Valeriana charges the stone, but Anne hears her friends screaming thinking their in danger and leaves. Anne found them, but they were actually fine and were instead watching cute animal videos. Marcy left with the group back to Wartwood not knowing the stone was not fully charged.
Before setting off to the third and final temple, Marcy pointed out that Anne that clothes were tacky and needed new gear, so she called for Newtopian armorer Bernardo. After Bessie saved everyone from blowing up, Anne finally got a new look, with it being just a chest plate over her old cloths, because she was finally feeling content with who she is. Sprig, Marcy and Bernardo approved Anne's decision, although Marcy thought Anne would look cute with a new hairstyle, much to Anne's chagrin.
When they reached the third temple, Marcy, Anne and the Plantars soon realized that the temple's trails were all about strength. They are rescued by Sasha who tracked them down with Grime. Marcy was happy to see Sasha and hugged her as they complimented their new outfits. Unlike Anne and the Planters, she was happy to let Sasha help them as she told about their quest to recharge the gems. They reached the final trail which was a giant rock monster with the power to increase the gravity around it; Marcy was rendered helpless because of the intense gravitational pull, but she watched Sasha defeated the stone guardian. When Sasha recharged the gem and Anne suggested opening it, Marcy stopped them and suggested that they should wait and bring it to King Andrias so they could know how to use it properly. Unbeknownst to Marcy, Anne and the Planters were right to be suspicious, because Sasha's change of heart turned out to be an act as she and Grime plan on invading Newtopia and are using them to get into the city.
