Hmm:
1. Beatrix Kiddo (Codename: [See my Avatar])
2. Sorter (He needs LASIK, though)
3. Garland 'The Marietta Mangler' Greene (We need to wear matching heads as hats, though. Any identical twins present?)
4. FPSRussia (dual-wielding AA-12s)
5. Patrick Bateman (Without the Mask)
6. Hannibal Lecter (Bring some Chianti)
7. Michelle Rodriguez (But since she's the very definition of Vasquez, her life expectancy is short)
8. Topper Harley (them's MAD M60 skills!)
9. Duke Nukem (Without Bubble Gum)
10. Chuck Norris*
*The only reason why Chuck Norris is not in first place is because the rules of Mathematics do not apply to Chuck Norris.
