The Syndicate

I'm not into those as much as comics (yay pictures) but you should all read Chrysalis.

Incredibly good science fiction story. Humanity is attacked by an alien race and all life on Earth is wiped out. But before going down, the last humans built an AI based on the human mind. The AI wakes up centuries later, realizes humanity is gone, builds a giant rocket and launches itself into space, with one goal: revenge.

Apparently this whole subreddit is of stories of humans kicking alien asses, but this story in particular is not just satisfying but also brings a lot of interesting moral questions.
