Wrong Place, Right Time: A Hero's Story by DLTA-BOT reviews
The journey of a hero doesn't always start where they expect. It doesn't always happen to those who expect it. Damon was never interested in being what SPARTANs represent: an implacable force for good standing as humanity's shield. Like most other third-generation SPARTANs, the war took everything from him. All he wanted was to return the favor. Sometimes we don't get a choice.

Code Lyoko:Crisis Core Part 1 by superman42 reviews
The only thing I can say is that this story is very disturbing. Chapter 3 is a self insert. I die to my worst fear. The name Stan Porter is my first and last initials. The third chapter is very screwy and disturbing. Part 1 is complete. There are twists and turns everywhere. Part two will make this look like Disney. Alt Continuity for Halo and Dead Space. Enjoy
