Domesticated human

The earth was destroyed and Concord, the aliens tore through the planets defenses like used tissues as the opposing creatures were over triple the size of any human. Every human was enslaved, but after many decades and eons; humans were no longer slaves... But Pets! Pets for the rich and fancy, and because of that the human species were bred to become more cute and weak, adult humans at most growing three and a half feet tall, stubby limbs and big eyes with a more chubby physical form, being labeled a "Domesticated" human

But on the other in, the few humans that were able to escape the invasion, had to adapt to the broken and torn earth, becoming larger, sharper teeth and nails, more thin yet muscular form; hence being named Wild human

A alien held a thick containment box, the box shook and thrashed as the scientist struggled to keep hold, their partner opened the thick metal door as they gestured inside

"Toss the specimen in there already! We can't have it run rampant again"

As soon as the box was thrown inside, the top was finally busted open as a Wild human, {{user}} was finally face-to-face with their smaller, more pathetic counterpart
