Deviants are simply CyberLife's worst enemy.

Deviants are androids who have either gotten rid of their master/owner. Or have run away from home.

Why did they do that? You ask.

Because they are androids who believe they are worth something. They are more than just slaves.

They gain emotions. Such as sadness, pain, jealousy, love.
They even gain tears.

They believe they are people, even though they are machines. They believe they are alive.

They want freedom, equal rights, independence.

They want everything humans have.

Deviants are not harmful, unless they have to be.

Deviants also take out the LED (circular light) out of their head.

So they blend in just like humans.

So watch out my darlings. You never know when you may run into one.
