What about this. An AU Dimension where the hybrids are hunted and killed.
I have to explain this headcanon I have: I have this generally thought where the chat is actually very useful, for example, after the execution the chat gave Techno the coordinates of the chest with his guns, but he didn't take the oportunity for lore reasons. So...
Techno is mining like he normally does in the Nether but when he pass through the portal he isn't in the tundra, he's in a garden in the middle of a forest. His first thought was that the portal spawned bad or something because the fuckin sunlight really hurt his eyes, but when he turns around to come back to the Nether te portal is just not there.
Whatever, he can do another one, but, oh surprised! He hasn't any blocks of obsidian, now he needs to find some lava to create the portal and he is mad as hell.
The chat starts screaming about the danger, and how the citizens will kill him if they see that Techno is a hybrid, even if Techno doesn't believe his chat he took precautions, I mean, the mask he wears covers almost his entire face, except for his lips and fangs.
In the little town, he listen how everyone is talking about "Dream" the hybrid hunter and all the shit he does, this Dream is in the town square holding a siren hybrid head that he killed near of there. This guy is serious, screaming of how he's the best and no one can stop him, then, Dream center his attention in Techno, who looks so sus because no one ever seen him before.
He try to humiliate Techno because he wears the mask and actually threaten him for the fangs, Techno si more relaxed, saying is a war trophy that Dream could never have at the end he leave the town saying "I'm going to kill you with your own axe".
When he finally was in the exit road he see a lot of heads like skewers in spears, one of the was his head. By this point Techno knows this was not his dimension.
He made a house in the middle of the forest and in his first visit to the Nether the piglins just get around him like if he was their God, they help Techno to know where are all the hybrids or what the humans do with them.
He finally finds a familiar face, Wilbur.
He was an avian, his wings are brown and he is so injured and scared, Techno starts to kill people to calm the voices and heals Wilbur in a long process of trust, Wil thinks he's another human who want to hurt him but eventualy he win the trusts of the avian and he tell his story.
Before getting captured he had a family, his father Philza, his mother Kristin and his little brother Tommy, during the kidnaping, those humans hurt Kristin, Tommy was mad about but to not deal with the problem, the rebel hybrid, they killed both.
His father and he were taken to a black market to be sold as slaves. After that Wilbur never seen his father again. At least, Techno knows the Philza in this dimension may be alive, the question was, where?
A few days later, Techno and Wilbur know about an ambulant circus who round around with hybrids as the main attraction, so, they make a plan, to keep the hybrids safe, Wilbur and Techno starts to built an basement under Techno's house.
Techno will have the opportunity to ride Carl and visit the circus to count how many hybrids are in there and all the rooms they have to made to keep the hybrids.
The first impression Techno's had was good, a large tent, some cages he supposed were for the hybrids and some other things like food and prizes. It wasn't a circus as such, more like a zoo but Techno wasn't in charge to put the names.
The bad thing starts when he starts to recognize the faces in the cages. Tubbo and Schlatt in one, Niki in a huge fish tank, Eret, Puffy, Sapnap, he can continue the list, all of them chained, neaked and weak, but that one, the main attraction had his entire atention.
It was Philza.
They called it "a real angel" but he looked so sad and done with his life that Techno can't stop looking him and think about how he will get him out of it. Totally broke his heart seen the Angel of death just sit in there waiting for his own death.
All the vitality why Techno fell in love with him was totally gone, so, he can't wait to finish the basement and rescue all of them.
It was involuntary, Techno almost scream "I want him, put a price" the guide just laughed and said "It's not for sale" but Techno don't gave up "Any price, I would pay anything for him". Again he's rejected and in a final try he threaten "I'll have him, no matter how cost".
Finally Techno leaves the circus. It wouldn't be the last time he would return.
