Chapter Text


  1. Pets are humanoid creatures that are hybrids of (generally) common pet animals.
    1. Non-domesticated animals cannot be Pets: no lions or tigers or bears, oh my!
    2. Some Pet breeds are more common than others, dogs and cats being the most common.
    3. The base animals the pets are hybrids of (such as rabbits) also exist in the world. However, they are NOT owned by humans as pets.  If the animal only exists because of domestication (for example, dogs), they will only exist as what they would be pre-domestication (wolfs).
    4. There are different variations of the same species. Think of all the breeds of dogs.  Some breeds are rarer, and in turn, more sought after than others.
  2. Studies have estimated the following information:
    1. Human to Pet ratio is roughly 8:1 and 3 out of 5 households own a Pet.

Physical Traits

  1. Pets have animal ears, tails, legs, and occasionally, other animalistic features (like whiskers/horns).
    1. The easiest example would be satyrs but of different animals.
    2. Sex organs are hidden under their fur.
  2. Reptile and amphibian pets retain additional human traits and are slightly different than mammalian pets.
    1. They have hair however only on their heads.
    2. Female (and Omega males when childbearing) will have breasts that are used to feed their young.
    3. Sex organs are hidden within their bodies unless currently engaging in sexual acts.
  3. They are shorter than humans, rarely growing taller than 5 feet tall.
    1. For the purpose of the story, take canon height minus 1 foot.
  4. They have better senses (hearing, smell, etc) than humans depending on the breed of animal.  
  5. They are intelligent creatures within a comparable range to humans.
    1. They can communicate with humans without any issues.
    2. If taught, they can read, write, do math, etc.
  6. Pets age at roughly the same rate as humans, and with a healthy lifestyle, can live just as long.
    1. At earlier ages of development, pets grow faster than humans physically but slower than humans mentally (0-2 years).  By the time they reach adulthood, the difference is minimal.

Quirks & Heros

  1. Quirks and Hero Society as a whole are still present in this AU.
  2. Pets can have quirks, but at a much lower frequency than humans.
    1. (Canon) human ratio of quirk to quirkless: 80/20
    2. Pet ratio of quirk to quirkless: 20/80
  3. People who had “animal quirks” in canon are now pets without quirks.
    1. *cough* Tsuyu Asui *cough cough*
  4. At the time of the story, there are no pet heroes.
    1. While there are no pet heroes, pets occasionally help in other hero activities. They’re just not licensed heroes.

Pets in Public

  1. The only required item of clothing for pets is a collar with tags indicating their owner.
    1. However, while a collar is the only required item of clothing, most pets wear clothing every day.  It is very unusual to see a pet without clothes in public.
    2. Tags have chips in them with addresses and phone numbers of their owners, some pet owners choose to also have a location chip added to the tags.
    3. Some “traditionalist” groups still walk their pet on a leash, but, like not wearing clothes, this practice is nearly nonexistent in the modern era.
    4. Some clothing items, such as pants, are specially designed for pets.
    5. Most pets prefer not to wear shoes.
  2. Pets can often be seen in public doing various activities and are allowed in most public places.
    1. It is common to see owners and pets on walks/runs together.
    2. Some pets do errands for their owner (such as getting groceries) as long as they have their collar and tags on for identification purposes.
  3. Pets can have jobs. However, it is rare.
    1. Jobs that pets have are normally low-level jobs.

Societal Pet Standards

  1. Humans generally like having pets for the social and health benefits.
    1. Think of therapy animals, seeing eye dogs, but most commonly for lifelong companions and as a part of the family.
    2. In the past, pets were treated more like animals or servants.
  2. Thanks to the hard work of pet activist groups, pets now have more rights than ever before.  Many commonly demeaning practices are slowly being put to an end.
    1. However, pets are still generally treated as a lower being than humans even if they can do just about everything humans can if they are given the opportunity to.
    2. In court systems, the word of a human is more powerful than the word of a pet.
    3. Even with all the effort being put toward pet rights, some less-than-savory practices, like pet breeding, are still legal.  Pet breeding is the act of forcing two pets to breed.
    4. Another policy these activist groups are pushing for is complete pet equality.
  3. Today’s society makes it nearly impossible for a pet to live without a human owner or benefactor.
    1. Pets do not inherently need human interaction, but most pets enjoy the stability, attention, and love that comes with living within a human’s household.  
  4. Pet adoption is a long process with many legal forms.  Upon completion, the owner has issued the pets identification tags.
  5. A pet can be adopted at several different stages of life. However, the most common and the most accepted are late teens.
    1. If people adopt from a breeder, they can adopt pets at a much younger age.
  6. Shelter homes are commonly filled with pets from many different backgrounds and walks of life.
    1. More often than not, they are filled with Alphas since they tend to be too aggressive for family life.
    2. Pets with potently danger quirks also often find themselves in long-term shelters.

History of Pets

  1. Pets started appearing at the dawn of human civilizations, long before quirks.
  2. No one knows exactly HOW Pets came to be, however, many scientific speculations have been made and regional myths and legends run rampant in trying to explain Pets.
  3. Different cultures over time treated Pets differently, some are very opening and accepting of Pets and others treat them as little more than animal.  

 Care & Grooming

  1. Each pet has needs indicative of their animal species.
    1. Hairy pets need additional time for grooming their fur to prevent matting as well as frequent bathing to keep their fur clean.
    2. Reptile pets require heating rocks and amphibian pets require water and a way to keep their skin from drying.
    3. Rodents pets need a means to keep their growing teeth short.
  2. Each pet has an energy level determined by the species of pet and personality of the pet.
  3. Each pet has a diet derived from what animal they are.  If a pet doesn’t follow that diet, they can get very sick.
    1. For example, dogs and chocolate.
  4. Pets mainly sleep in nests.
    1. Omega pets, in particular, need and make nests.  An Omega may build a nest for the following reasons:
      1. They are preparing for their heat.
      2. They do not feel safe with their surroundings.
      3. They are pregnant and preparing for their children.
      4. They are protecting/nurturing their children.  Note: Isn’t always their own child, or child at all. 
    2. Some pet owner allows their pets to sleep with them at night. However, Omega pets normally return to sleep in the nest during their heat for the privacy.
  5. Sleeping habits of pets are the same as the animal species they are.


  1. Pets live under Alpha/Beta/Omega Dynamics.
  2. The breakdown:
    1. Alphas are males 75% of the time and females 25% of the time.
    2. Omegas are males 25% of the time and females 75% of the time.
  3. Omega pets have heats one time a year at no set time.
    1. There are medications out there that can jump-start a pet’s heat.  Under these circumstances, a pet can have more than one heat in a year.
    2. Similar medication can also be used to increase the fertility of a pet.
    3. An Omega’s heat will last 5-7 days.
    4. An Omega will generally know when their heat is coming by the timing and other telltale signs.
  4. Biting is common in the mating process, but it doesn’t bond an Omega to an Alpha.
  5. Humans do not have secondary dynamics.

Pregnancy & Children

  1. The length of pregnancy, the number of children, and the birthing method all depend on the pet species.
    1. A rabbit has a 4-week pregnancy.  Humans have 36-40-week pregnancies. A pet rabbit would have a 20-22-week pregnancy.
    2. Rabbits can have a range of 1-14 kits per pregnancy. However, 6 is the average.  Human’s average is 1 child per pregnancy. A pet rabbit, on average, will have an average of 3-4 kits per pregnancy.
    3. If an animal has live births, the pet species will have live births and etc. NOTE: All species, even ones that lay eggs, still breastfeed their young.
  2. When two different pet species breed, the resulting children will be one or the other, not a combination of both.
    1. It should be noted that different variations of the same species will produce mutt children; think of dog breeds.  (Ex. Poodle + Lab poodle = Labradoodle)
  3. When two different pet species breed, the length of the pregnancy, the number of children, and the birthing method will be that of the “mother’s” species.
    1. This means it is possible for a pet dog to be born from an egg.

Human-Pet Relationships

  1. Humans and pets can breed and produce fertile children with one another.
    1. The resulting children often look more human than full-blooded pets, not having the telling animal ears, tail, or legs.  In addition, they generally grow up to a human height and have less powerful senses. In rare occasions, it can be nearly impossible to tell that a person is half pet.
  2. Human-Pet relationships are highly looked down upon society.
    1. Some people look down on it because they think pets are lower beings and would treat it like bestiality.
    2. Others dislike it because they do not believe there could ever be a healthy and truly consensual human-pet relationship with the current societal norms being the way that they are and because of the disparity in power between owner and pet.
