I'm an assassin. Black ops. When the Resonance Cascade occurred at the Black Mesa Research Facility and the marines failed to contain the situation, I and my team were sent to clean up. My team was wiped out by a marine, Adrian Shephard. He interrogated me, clubbed me half to death with a wrench, and he's an idiot. I hate him. I HATE HIM! I barely survived, left partly disabled. When the Combine invaded, I joined the Overwatch, became a transhuman. I'm faster and stronger than ever.
