Guu

Guu is the secondary titular main protagonist from the Hare+Guu anime and manga.

Guu is a mysterious being with the appearance of a little girl, but is clearly far more than what she seems, possessing very ambiguous morals and abilities that allow her to do almost anything she desires.

In the AWA fics, Guu is a student at the AWA Academy and is part of Class 5.

Appearance
Although no one knows what Guu's true form is, there were four distinct forms seen in the series:

Shadow Form
This form was used in the first episode, when Hare first encountered Guu while gathering bananas. Guu in this form takes the appearance of a large silhouette creature (roughly resembling a pokute) that chases Hare. It tries to swipe him with its claws, but he jumps over them. It then takes the form of two black tentacles that tickle him so he can stop running. It manages to eat him the first time, after Hare slips on a pokute.

Social Form
This form is used when Hare first meets Guu. This is the second form she takes and resembles a cute little girl with pink/white hair, deep red eyes, a cute smile, pale skin, and a pink dress with a yellow sash tied around her chest. Her city outfit consists of a light blue jacket, black pants, and red sneakers. While in this form, she seems to adopt a shy personality. Guu uses this when she meets new people, but eventually drops it when she gets used to them.

"Normal" Form
This is the form she used regularly within the show. Although she retains the pink hair and pink and yellow dress, in this form, her eyes are black, her mouth is not usually visible, her face shows barely any emotion, and when she does show emotion in that form, she creeps Hare or others out. Some of the villagers don't seem to notice the difference between her "Normal" and "Social" form (excluding Hare, Lazy-Sensei, Doctor Clive, and the school children). When Hare tries to prove otherwise, he nearly goes insane when people contradict him.

Adult Form
This form is rarely seen, maybe once or twice. It was first seen when she fought a bear that had attacked Hare. She has an adult figure, slim with slender arms and legs and a thin face. Her eyes are narrow with an angry look to them. They're dark pink with small pupils and no shine. Guu's hair in this form is very long, extending past her knees. Her bangs hang over her eyes and the hair itself is messy, flying everywhere, but it is otherwise the same color as usual. Her dress and sash seem to have grown along with her body, covering as much as it did before and is much the same style. She still has a rather expressionless face. In this form, she displays astounding wrestling skills, easily subduing a bear with her pro moves (and apparently killing it, as Guu is later seen in her normal form using it as a "fur coat").

Personality
Guu normally has a dull and expressionless face, befitting as she rarely shows any genuine emotion. She is very ambiguous when it comes to her true intentions and morals but always seems to have some greater goal in mind which either involves a humorous way to torment Hare or simply perform some crazy shenanigans, however most of the time it appears that her actions, which early on did not help anybody eventually turned into a genuine form of aid for the residents of the jungle, including Hare, as they at first seem dangerous, insane and maybe even cruel but at the end her actions manage to resolve a dilemma within someone's life, most usually Hare who normally suffers due to Guu's insane antics but at the end learns something that needed to be known to mature and help his friends, albeit he still suffers due to all the torment in between.

At first, Guu did not seem to care much for Hare or the villagers and simply enjoyed tormenting them at first, but appears to have genuinely grown fond of them despite her emotionless personality not showing it (or she may have never genuinely had any dislike for them and simply humorously tormented them as some form of "game"), and she always leads Hare through her antics to help him or the rest of the village with their problems. She appears to be closest to Hare for reasons never fully understood and always accompanies him wherever he goes and finds ways to mess with him or teach him a lesson in her own weird way. Weda, Hare's mother is the only one Guu seems to never involve in any dangerous antics, likely due to her acting as an adoptive mother to Guu.

Guu has a very "robotic" way of laughing in which her head will bobble in a toy-like fashion while making dull "HA" sounds.

By the end of the series, she erased the memories of her existence from everyone who ever met her except for Hare, showing that she may have genuinely cared about the memories of them spending time together more than anyone else's. She would later on choose to be reborn as Hare's daughter, likely seeking to be a part of his life and family once more.

Adult Guu
Guu's adult form seems to have her own separate personality, although whether she is an independent being or another side of Guu's personality is not known. The adult form is the exact opposite of Guu in both appearance and personality, being calmer, less deformed, more serious and seems to care more about the happiness of the beings living inside her, and while she is just as emotionless as Guu her appearance never changes and her words always seems to hold sincerity. It is possible she is Guu's orderly half while regular Guu is the chaotic half.

Abilities
Guu is a being of incredible power, capable of almost of any feat imaginable or unimaginable. She can freely alter reality as she sees fit to suit her needs and usually does so to simply torment Hare in a humorous fashion. Near the end of the series, Guu reveals to Hare that she is actually a goddess, explaining how she was capable of so many amazing things, making her basically omnipotent, omnipresent and possibly omniscient.
 * Shapeshifting: Guu can change her appearance into several forms, although her true form is unknown. She can turn herself into a human child (her most common form), a human adult, a shadow monster, and a giant kaiju-like monster. She can also alter the appearance of her attire into whatever she feels fits her current situation. She can also alter parts of her body into anything, such as turning her elbow into a machine gun and sprouting numerous eyes.
 * Elasticity: Guu can alter her arms and usually most of her body so they can stretch to impossible lengths and move in a rubbery fashion. She can also open up her mouth to a grand size to swallow people or creatures and she can grow to enormous sizes.
 * Super Strength: Guu has incredible physical strength, capable of lifting things several times her size and overpowering anyone. In her adult form she was shown defeating a large bear with ease.
 * Omnivorous: Guu is truly the definition of omnivorous, having two stomachs and there is apparently nothing that she cannot eat or swallow whole, however most of the inedible things she eats along with whatever people she swallows end up in her alternate world-like stomach where she keeps guests while regular food likely goes into her other stomach.
 * Omnipresence: Guu possesses the ability to appear anywhere she wants (usually at times that will be inconvenient to Hare). She can move at high speeds and teleport almost anywhere she wants. She can also travel through time and even into pictures, showing she has complete mastery over space and time.
 * Reality Manipulation: Guu can freely alter her surroundings and the appearance of others in whatever way she wants and seems to have complete control over reality.

Guu's Stomachs
She possesses two stomachs and one seems to act as its own separate world filled with all manner of bizarre creatures, terrain and structures. There are also three Japanese humans residing within her for reasons unknown who are not bothered by their predicament very much. She claims that this stomach is for guests only while the other stomach was never seen but is likely where her actual food goes.

Trivia

 * Guu seems to have a strong interest in cats during the course of the series. There were several points that supports this.
 * She is seen sleeping on a television set at Hare's home in a similar fashion of a real cat.
 * In one episode where she, along with Hare, dressed up as pets, she was the cat and Hare was the dog.
 * When she, Hare, and Weda were in the city, she at one point in Weda's Mansion, licked her hand and curled up like a cat.
 * Cats are normally stereotyped as favoring seafood, a trait shared by Guu. The first thing she ate that didn't surprise or anger Hare was Weda's shrimp gumbo. When she dressed up as a cat, she was pleased to receive a trout and halibut for dinner. In addition, she ate fish on several occasions in a couple of episodes.
 * One of the main inhabitants in Guu's stomach were cats with many legs (She even used one as a trumpet in the ending song on Hare+Guu DELUXE).
 * Interestingly, the fact that she appeared sweet and cute when Hare's mother introduced her then turning bland and troublesome the day after can be seen as mirroring some cases where cats act calm and timid when first introduced to a family, and once they get used to them, they reveal their more playful and slightly mischievous side.
 * While not mentioned or confirmed in the series, Guu's human form seems to be an albino (A physical disorder that describes the lack of pigment). This may explain Guu's light colored hair, red eyes and pale skin, and how she lives in the jungle yet has no signs of tanning.
