Gender Female ♀ Height 172 cm (5"8) Weight 55 kg Eye color Sclera: Yellow Iris: Black Deep indigo (Early) Cyan Leima (Chinese: "莱玛" Léi mǎ) is one of the characters in Terrible Mouse. In The Bullied Rabbit, she is one of the Protagonists. Backstory Before arriving at the Hospital, Leima was subjected to an experiment, during which venom merged with her blood. As a result, she became immune to toxins. It can also be assumed that the experiment is what likely caused her to become a hybrid between a cat and a rabbit. Afterwards, she ended up in the hands of an owner, who eventually abandoned her because of her appearance. Apperance:

Main Appearence Physical Appearance

Leima is a fusion of a cat and a rabbit. She has a very light purple fur, yellow sclera and cyan iris. She has a pink heart-shaped nose and purple cheeks, resembling a blush. She also has purple hair styled into two double low buns with white hair ties that appears to be white beads. She also has a large, black birthmark around her right eye.

In the teasers, the tips of her ears started to appear muted purple color.

Clothing

Leima wears a white doctor's gown and white shorts underneath, a dark purple skull as a button, a small dark purple bag, and a nurse's hat with a black skull on a dark purple heart as a backround.

Other Information

Due to being involved with various fights, she has many scars on her skin, which makes her appearance look very unappealing to many. She therefore uses makeup to cover and hide her wounds. Her blood is also purple and poisoned.

She often hides her left eye with her hair, this is due to a large black birthmark around it.

Her iris was early had Deep Indigo color, but was changed to Cyan.

Info

Leima's appearence is almost the same. But she has a small heart paint a little below her neck, she also has dark purple skull on the chest and has white hat with a purple heart on it and a black face resembling skull. Her sclera appears to be yellow and iris appear to be dark purple. Personality Leima is selfish and very beauty-conscious, and she would go crazy if her appearance were ruined, even if just a little bit. She hopes that someone or anyone will like her, even if this will be a human.[1] She is also likely paranoid due to her frequently getting bullied. The bullying Leima suffers is simply because she doesn't hate humanity as much as the Hospital staff do, so they act as if she's a monster for not hating humanity that much.

Leima has a rivalry with Lorna, for a personal reasons, - she is jealous of Lorna's nursing skills and the positive attention of hospital members, mainly male mice.[2] Leima doesn't have the same treatment with other animals, and mostly gets into fights, creating new bruises and scars for her to cover.

She seems to trust Damm when he was a human, he was the only kind person to her (if not expect her sister Leilu). When Leima discovered about Damm's death, she became enraged to the point of breaking in and torturing Lorna inside her own room for vengeance. Furthermore, in Bullied Rabbit, Leima is seen in a state of extreme rage, going after Pukasi with all her hatred, She also stated that if Damm were dead, she would not spare Pukasi.[3]

Leima possess more human-emotions than most of the hospital staff. She can be dramatic and emotional and also feisty. Relationships Hospital Members: Leima was often disrespected and bullied for her unattractive appearance. She is also hated for having a neutral opinion on humans, and is called a traitor, unlike others. Despite this, Bloodbath has apparently not taken any action to manage the problem.[1]

Leilu: Fortunately, her younger sister, Leilu, deeply cares about her and often tries to comfort her when she is in a bad mood. Similarly to her sister, they also shared the strong dislikes against Lorna.

Leima is worried about Leilu, and she didn't like that Leilu saved her. Not because she dislikes Leilu, but because she didn't want Leilu to risk her life to save her. It's clear that Leima truly loves her sister; apparently, she sees Leilu as the only person she can truly trust.

Lorna: Leima is jealous about Lorna's skills on taking care on animals, and attention by male mice. She was never praised by other males for her beauty in the hospital. So on, Leima often projected her hatred and belittles Lorna among with her sister, bullying Lorna when she cannot fight back. Especially after she murdered Damm, the only human Leima trusted. Leima were frustrated that Lorna has a lack of empathy, her coldness made her blood boil and proceeds to beaten her inside her room, attempting to kill Lorna to avenge her human friend. But it failed when Lorna escaped and report her, for siding with the humans. Damm: When Leima met Damm, she attempts to tortured him, but a hint of hesitation of her eyes. Recalling the events where she gets heavily bullied by Lugus for being unattractive, and liking humans: humiliated her in front of animals in Canteen room. Leima breaks down into tears of and frustrated that she isn't well-liked by many. Damm was confused at glance, but she glares at him, thinking that he thinks she's ugly as well.

Before Leima could attack him, she quickly pauses when Damm told her she was beautiful and her accessories are exquisite. Leima was flattered and spared him, freeing from the ropes. The two then gained alliance and she tries to hide him inside the portable garbage to avoid getting caught.

But when she was sent to the Canteen, where her bully frequently visits. Leima tries to defend herself and protect Damm from the hospital staff, technically failed when Damm was discovered by Lugus inside the trash. Leima tried to attack Lugus behind, then gotten paralyzed by Pukasi's spell.

Damm holsters his gun and kept shooting at Lugus, however, Lugus was too fast and gets the upper hand. He electrocuted him to the ground, laying there helplessly. This is where Lorna spotted a human on the floor, and takes him away towards her torture room. Leima declares if her human friend dies, she wouldn't give mercy.

After Damm's disappearance, Leima realizes Lorna have killed him and became furious. To avenge her human friend, she confronts Lorna by barging into her room, and tying her up. She violently tortures Lorna, asking why did she killed him. Lorna responds in her bratty nature, and this enraged Leima more - for her lack of remorse for humans. She proceeds to beaten her up relentlessly, attempting to kill Lorna, telling her she should die.

Suddenly changes, when Leima spotted Damm (now in a human and slime hybrid, so she didn't recognized him and Damm didn't recognized her as well since he lost his memories after transformation) who was trying to escape, Leima told him if he witnessed it, but she quickly become disgusted of his slime goo as it sticks in her clothes and hair. Leima retaliates by clawing him, injecting him with poison, but her efforts are futile when her poison didn't worked against him. Leima was surprised and pinned down by Damm, gluing her down to the floor. Leima watches the slimeboy rescuing Lorna in his hands. Leima told them both of them should joined-to-die. While being immobilized and panicked, Leima screams Leilu for help.

Lugus: Leima was Lugus's main target for popularity, since she was mostly disregard and called a traitor. Leima has to endured through harassment and physical abuse from Lugus.

Lugus imagines himself beating her up to gain a higher reputation. Yet, Leima was stronger, able to standoff against him. She defeated him with poison in the Canteen.

At the end, Lugus was shown to be inside the hospital bed: bandaged and angry that he lost against Leima.

Pukasi: Leima ended up attacking Pukasi and going after him in a fit of rage, because he was responsible for arresting her without being able to help Damm in the fight. Hospital Owner: The Hospital Owner demonstrates a poor relationship with Leima; he quickly lost his temper with her and threatened to shoot her if she'd won't open the box. But he seems to have future plans for Leima, since he sent her to the Canteen to see how strong she is, and even knowing that she betrayed the organization, he didn't order Leima to be killed.

Pula: It is known that Leima knows Pula and is aware of what happened to her, but not much else is known about their relationship other than that Leima wondered how Pula was doing after everything involving Pukasi.[4]

Abilities/Skills Poison Immunity: Similar to Leilu, Leima is immune to poison and toxins. Poison Claws: She can inject poison into people by clawing them, draining their health. Though this does not seem to work on some characters including Damm, that is made of slime. Leima's claws are extremely strong, as she was able to break the ground with them.

Resilence: Despite getting bullied and scars covered by her makeup, Leima has a good stamina and refuses to back down easily. She is shown to be the strongest hospital members. Trivia Leima is the older and twin sister of Leilu. In her introduction sheet, Leima's name is sometimes written as "Rema". This is a translation error, as confirmed by Gutian. Leima (and other animal characters) appears before the first episode on the official page of Gutian at Bilibili, now currently empty (due to complaints). Leima is, as of Episode 4, unaware that Damm was transformed into a slime/human hybrid. In Episode 3, she appears on a portrait alongside with Lake and Leilu. Her appearance looks slightly different than in Episode 4 and onwards. It is possible that Gutian used old character design for portrait. Within the Escape from This Place universe, Leima has a pink color tone instead of purple. Still in the Escape from This Place universe, Leima is a mouse and not a rabbit and she had no birthmark. It also seen in Untitled Lorna Animation Test and Episode 1 of Terrible Mouse. Leima hates Lugus too, that she suffered in the Canteen and what he done to Damm. Leima's claws are made of adamation. Perhaps Gutian drew inspiration from Wolverine for that detail in Leima. Leima is the only hospital member who has the least hatred to humans due to abandonment and appearance. It is implied that she has a drinking problem, because there are bottles in the scene where Leilu comforts Leima. In Gutian post of Leima getting called "ugly", Damm (human form) appeared as a photo: meaning that Leima kept his photo as a memento and she misses him. It's one of the main reason why she was disliked and bullied by other animals in the hospital. Damm was her first friend human. Leima accidentally saved Pula from Pukasi. Leima doesn't knows about Pukasi's intentions, It's because Leima is focused to kill Pukasi for responses of Damm. In Bullied Rabbit, Leima is first seen in the Execution basement with her birthmark exposed, But as soon as she reappears at the Canteen, her birthmark is hidden beneath her hair. This reveals that as the elevator went down, Leima hide her birthmark so the animals would no longer have reason to curse her. In Episode 4 on the door to Leima's room, her name is misspelled; it says "Liema". Also, in the scene where Damm is running, Leilu's bedroom door has "Leima" written on it for some reason. This is most likely an error too. Leima's blood color is purple. It also seen in Bullied Rabbit when Pukasi beating her. And it is also noticeably on her wounds. However in Bullied Rabbit, when Lugus imagining how he beaten Leima, Leima's blood appears to be red. Most likely because Lugus doesn't knows that Leima's blood color is purple and not red. Leima's blood is poisoned as well. It seems that Leima's birthmark was a detail that Gutian added to Leima only during the production of The Bullied Rabbit, since in Episode 4, in the scene where Leima turns around, It's possible to see her other eye without her birthmark.[5] Or probably Gutian just forgot to add that detail to Leima in Episode 4. In Episode 3, on her portrait she appears without birthmark too, and her hair does not covering her eye. In Episode 5 (Part 2) from Leima's mouth slightly flows blood; in that scene her blood appears to be red. Interestingly, in the teaser that Gutian made on June 17, 2026, showing Leima is being beaten, Leima is missing her birthmark.[6] Leima has a soft yet unsettling presence, her appearance blending elegance with something subtly unnatural. Her skin is pale with a faint lavender undertone, giving her a slightly lifeless, porcelain-like quality.

Her hair is a muted violet shade, styled into short, rounded twin puffs at the sides while the rest falls forward in thick, uneven bangs that almost completely cover one side of her face. The texture appears soft but slightly messy, with strands overlapping in a way that obscures her expression. A small nurse-like cap sits atop her head, simple in shape, adding to her clinical yet eerie aesthetic.

One of her most striking features is her face—specifically the dark, ink-like void that consumes one side of it. This shadowy patch spreads across her eye and cheek, appearing unnatural and almost liquid in how it contrasts against her otherwise pale skin. From within that darkness, a single yellow eye stares out, sharp and unsettling, with a small, focused pupil that gives her a constantly observant, almost predatory look. Her other eye remains hidden beneath her bangs, adding to the mystery of her gaze.

Her expression is typically calm and unreadable, her small mouth often set in a neutral or slightly downturned shape, rarely showing strong emotion. A faint blush rests across her cheeks, though it does little to soften her overall eerie presence.

She wears a simple white outfit resembling a nurse or caretaker uniform, fitted neatly but without excessive detail. Around her neck hangs a dark, skull-shaped pendant, resting at the center of her chest, acting as a stark contrast to her otherwise clean attire and hinting at something far more ominous beneath her role.

Overall, leima carries herself with quiet composure, her appearance giving off a sense of control and detachment, while the unnatural elements—particularly her eye and the darkened half of her face—create a constant feeling that something about her is deeply wrong.

2. character: Leilu (Chinese: "雷璐" Léi lù) is one of the antagonists of Terrible Mouse. Appearance Main appearance Physical appearance

Leilu is a hybrid between a rabbit and a cat. She has a very light pink fur, she has pastel pink sclera and magenta red iris and black small dots as pupils, pink hair styled into two pigtails that tied with hair ties that appears to have golden yellow color and a pink heart-shaped nose. She also has slightly purple cheeks, resembling a blush.

Clothing

Similarly to her sister Leima, she wears a white doctor's gown with a dark pink skull as a button, a small dark pink bag, and a nurse's hat with a skull on a heart. Her blood color is most likely purple, as a result of her blood merging with poison during an experiment before she ended up at The Hospital.

Other information

Her appearance were slightly changed in The Bullied Rabbit; the tips of her ears became pink.

In a sneak peek of a work-in-progress project, her hairties seem to be pink instead of yellow. Personality In difficult or complicated situations, Leilu adopts an explosive and impulsive stance, even more so than her sister, Leima. It's possible that Leilu has a more difficult temperament than Leima, given her rage in Catch My Arch-Nemesis, where she killed two rat guards and attacked Lake, only calming down after she was finished. It seems that when faced with a situation involving her sister in trouble, she acts aggressively to resolve the situation quickly and save/help Leima. She also appears to be resentful, as she hates Lorna with all her might, possibly due to the rivalry between Lorna and Leima.[1] But it's also noteworthy that she held a grudge against Damm, because she remembered when Damm trapped her and Leima on the ground with his slime. It's possible that Leilu harbors this hatred for Damm because she blamed Damm for Leima being imprisoned in the Execution basement, or because Damm incapacitated her and Leima. She only changed her mind when Leima convinced her to trust Damm. Even though Leilu can be aggressive at times, she has a caring and affectionate side. This is evident with Leima; she cares deeply about her sister and risks everything just to save her and ensure her well-being. She doesn't care that Leima is helping a human and has broken the rules; she simply wants to make sure her sister is okay. Relationships Leima: She treats her sister with great affection, and she helps and comforts Leima even in difficult times. And she also hates Lorna along with Leima. She truly cares about her sister and genuinely loves her, as seen in The Bullied Rabbit; she even cried knowing what her sister was going through, so much so that she blamed herself for it.

Knowing that Leima was being punished in the Execution basement, she went to her and saved her sister, showing the extreme affection and attachment she has for Leima. Leilu doesn't care if something might happen to her while saving her sister; as long as Leima is safe, that's enough for her.

Lorna: Similarly to Leima, Leilu often projected her hatred and belittles Lorna among with her sister Leima, bullying Lorna when she cannot fight back.

Damm: Ever since Leilu met Damm, she had a slight hatred for him, probably since he doesn’t remember his past with Leima. She showed resentment upon seeing Damm again, but Leima convinced her that Damm could help them, so Leilu likely sees Damm as an ally.

Abilities Poison Immunity: Similarly to Leima, she is immune to poison and toxins. Claws: Like Leima, Leilu has claws, which are pointed and sharp; it is unknown whether Leilu also has adamantium claws like her sister. Poison Claws: As her sister Leima, she can inject poison into people by clawing them, draining their health. She might be have this power too, since she is anative sister of Leima

Victims Victim Episode Way of death Lake Catch My Arch-Nemesis Leilu, not wanting to be defeated and wanting to save her sister, used her claws on Lake, thus managing to poison him. Lake was seen writhing on the ground as the poison took effect.

Trivia Leilu is the younger sister of Leima. She is also her twin sister. In Episode 3, in the part of the door's appearence, Leilu appears with her old design. Leima appears with her old design too. In Episode 3, in the part where Luke and Robbie see the paintings of Leima, Lake and Leilu, Leilu has a slightly different design than in Episode 4. Leima has an older design in this part too. Perhaps Gutian used old character designs for the pictures of the paintings. Leilu was formerly been a rat in Escape from This Place universe and Untitled Lorna Animation Test. In Episode 4 in the scene where Damm is running, Leilu's bedroom door has "Leima" written on it for some reason. This is most likely an error. In Leilu's introduction sheet, Leima's name is misspelled as "Rema". Somehow in Chapter 1: Catch My Arch-Nemesis, Leilu's face is white/pale. Also, she is not seen wearing makeup (those purple blushes on her face, when her design was featured in Episode 4). Possibly because she's hungry and hasn't eaten in days.

The sisters has a brightly colored yet unsettling appearance, blending a playful, almost mascot-like design with subtle details that hint at something far more unstable beneath the surface.

Her skin is a soft, pale lavender tone, smooth and almost plush-like in texture, giving her a slightly artificial, toy-like quality. Her body is petite but softly rounded, with a light, nimble build that supports her energetic and unpredictable movements.

Her hair is a vivid pink, styled into two short, bouncy twin-tails tied with small yellow bands. The hair itself is thick and slightly fluffy, with layered bangs that sweep heavily across her face. One side parts just enough to reveal her eye, while the other merges into a dark, shadowy patch that covers the opposite side of her face entirely, creating a strong asymmetrical look.

That shadowed portion appears unnatural—like a stain or corruption rather than simple shading—completely obscuring one eye and adding a constant eerie imbalance to her otherwise cute design.

Her visible eye is large and striking, colored a bright, intense red with a dark pupil, almost glowing with energy. It’s highly expressive, often wide with excitement or narrowed with mischievous intent. Beneath it, faint purple markings or bruised-like shading add to her slightly worn yet manic appearance.

Her mouth is small but frequently stretched into a wide grin, revealing sharp, fang-like teeth that contrast heavily with her otherwise soft features. The smile carries a playful tone, though it often borders on unsettling the longer it lingers.

The sisters wears a stylized nurse outfit, primarily white, short and fitted with a soft, dress-like cut. The sleeves are slightly loose, giving her movements a light, flowing feel. Around her waist is a thick, dark magenta sash tied into a large bow at the side, adding a bold contrast to the outfit.

At the center of her chest hangs a small skull emblem in matching dark magenta, reinforcing her theme of cute mixed with dangerous.

On her head sits a white nurse cap, decorated with a pink heart symbol that contains a small mischievous face inside it—almost like a logo representing her personality. The cap rests between two large, upright ears resembling those of a rabbit, pale in color with soft inner shading, further enhancing her hybrid, creature-like nature.

Her limbs are smooth and simplified in shape, with rounded hands and feet that lack defined fingers or toes, adding to her stylized, almost doll-like anatomy. Despite this, her movements are quick and expressive, often exaggerated in a playful way.

One notable detail is the faint presence of a purple, ink-like substance occasionally visible on her fingers, as if something is staining or leaking from her touch—subtle, but noticeable.

Overall, The sisters gives off a chaotic duality: outwardly cute, colorful, and energetic, yet layered with visual hints of instability and danger, making her feel both inviting and deeply unpredictable at the same time.

she tends to use her long sharp claws more offten when fighting or when shes just pissed

Additional Context: Leima is currently marked as a target within the facility after crossing multiple lines and going against the system. Her actions have caused widespread consequences, leading many mutants to suffer as a result—something that has made her widely despised.

If other mutants encounter her, they are likely to:

• Become immediately hostile
• Attempt to capture or eliminate her
• Alert others of her presence

She is not meant to be free, and her existence outside containment is considered a direct threat.

Leilu is fully aware of this and remains constantly alert, often acting as the more controlled and strategic counterpart when dealing with these situations.

When encountering humans, however, the reaction becomes far less predictable. Both sisters may respond differently depending on their mood, condition, or current objective—ranging from indifference, interrogation, manipulation, or outright hostility.

Despite everything, Leima shows no intention of backing down, and Leilu has no intention of leaving her side.

Deeply loyal and protective of each other

Often act as emotional opposites (hot-headed vs. composed)

Both share a strong distrust—and often hatred—toward humans

Will cooperate seamlessly in fights or tense situations

Their interactions can shift between caring, tense, or dangerously synchronized
