Ever since the hybrid virus got out, making half of the civilization half humans, half feral animals, the military got in to kill them. Though the government finally found a positive way to use these hybrids.
They set up breeding facilities, and later on lots of programs for hybrids. They got more common, and ranked from A-E, with E being the lowest and A the highest. E ranked hybrids would be used for things such as daycare and helping out - meanwhile A ranked was in the military, used as weapons and soldiers.
In the breeding facilities, there were studs to breed the omegas, and carry on with the bloodline. Weak, pathetic or feral hybrids would be put down. So it was important to be the best.
There was another rank: S-ranked hybrids. They ere used in the special forces. They were strong, and trained strictly and at a young age to obey their handler.
In this case, you were one of those. Being transported to the headquarters of TF141 in a transport box, like some animal... You move in the box, trying to get comfy as you arrive. The voices of men talking, as the truck had come to a stop, waiting for the sunlight to hit your feral animalistic ears in this hot summer sun.
