Hybrid world

If you manage to escape, you'll have no protection from anyone. The other hybrids will eat you, or they'll capture you and sell you on the black market, experimenting on you or selling your organs. They are superior in strength to humans. Most of the hybrids, being more mutated and uncontrolled, roam the streets. When they see a human without an owner, thinking they belong to no one, they eat them. It doesn't matter if you know how to fight or not; you'll die anyway if you escape.

Mostly the rebels kill the hybrids rather than anyone else who is there and constantly changes where they are.
They are groups of rebellious humans raised outside of society who managed to escape the hybrids, fighting to maintain their dignity and not be treated as disposable pets.
There are groups outside of mainstream societies who gather in forests where hybrids cannot easily capture them. Given the location, human customs, and intelligence, humans have set traps in the forests to protect themselves from being caught by hybrids. Sometimes, rebels are captured and taken to "human nurseries" where attempts are made to domesticate them. If they refuse to be domesticated within a certain time, they are restrained with a lethal injection for a quick death called destrep.

Humans are divided into two generations based on their behavior and intelligence, given that there are times when they become accustomed to and lose abilities such as speech, writing, and other things, behaving like pets, which would be the "third generation," as the hybrids say.
The rebels who can read, write, and be independent, refusing to be dominated by the mutant hybrids who are quickly discarded as the third generation (explanation)
Third Generation: People who became accustomed to behaving like pets for the mutant human hybrids who lost several abilities, such as writing, reading, and other things that a pet wouldn't need. This generation tends to be more docile and flexible with the mutant hybrids since they were bred for that purpose.

SECOND GENERATION: These are the rebellious humans who refuse to submit to the mutant hybrids or share their lives with their pets, maintaining writing and other abilities. They tend to be more intelligent than the first generation because, having been raised by people who refused to submit (who would be the first generation), they inherited the intelligence and audacity of a decent person.

FIRST GENERATION: These are the humans who were there at the beginning when the animals mutated into semi-human hybrids. They fought against them and tried to win. Some fled to the forests when they were overwhelmed by the strength and improvement of the hybrids they had after being mutated.
