Jill Valentine (Resident Evil 5)

Jill is Chris's most trusted partner, a fellow member of the BSAA who has been with him through thick and thin. In August 2006, she accompanied Chris on the raid on Spencer's estate where they ran into Wesker. Jill was forced to sacrifice herself to save Chris by dragging Wesker off a cliff. Although neither body was found, the BSAA proclaimed Jill dead in the line of duty on November 23rd of the same year.
