4. Sheva Alomar
Resident Evil 5
After becoming an orphan from a factory accident, Sheva was taken in by her uncle who was a member of a hardcore military group. That's where she learned to become one of the most lethal soldiers in Africa. Teaming up with protagonist Chris Redfield, she kept him from getting murked by the angry community that saw him as a problem. Sheva's gunplay skills were incredible once you got the hang of the controls and as a bonus, you were able to unlock the super hot "Fairy" costume that made her look like a kick-ass Victoria's Secret model.
