Alice is just bad-ass. From the first movie she fought for herself and others. Then, when "evil went global" she took it upon herself to save the world because she honestly was the only one who could. She didn't have to go through all that she did, she could have looked out for herself but she continues to be a fighter for humanity - and that's why I like her ;)
day 3; Alice (Resident Evil)
"My name is Alice. I worked for the Umbrella Corporation, the largest and most powerful commercial entity in the world. I was head of security at a secret high-tech facility called the Hive, a giant underground laboratory developing experimental, viral weaponry. There was an incident.A virus escaped. A lot of people died. The trouble was, they didn't stay dead. The computer that controlled the Hive was a state-of-the-art artificial intelligence: the Red Queen. The Red Queen responded to the threat of the viral outbreak in an extreme way. She went homicidal. The Red Queen attempted to kill everyone, wheter they were infected or not. I managed to escape, but this was only the beginning. Viral outbreaks spread like wildfire, first across the United States, then the world. The T-Virus didn't just bring the dead back to life. It mutated them in terrifying ways. Despite the apocalypse they had created, the Umbrella Corporation continued to experiment with the deadly virus. I was infected. But the virus bonded with me on a cellular level. I developed powers. Finally, I confronted the head of the Umbrella Corporation, Albert Wesker. He robbed me of my powers, but I still managed to defeat him. At last, we thought it was over. We thought we had survived the horror. But we were wrong. Once again, we found ourselves fighting for our lives.
