Lady Killer

Lady Killer or Black Widow (depending on the Player Character gender) is a Fallout 3 Perk.


 * Requirements: Level 2
 * Ranks: 1
 * Benefit: In combat, you do +10% damage against (the opposite sex) opponents. Outside of combat, you'll sometimes have access to unique dialogue options when dealing with the opposite sex. (The latter is much like the Sex Appeal Trait)

Additional Dialogue Options
If you are Male:


 * Nova in Megaton will provide you with the password to Moriartys terminal.
 * Brianna in the Blood Ties quest will provide you with the password to Ian West's cell.
 * You can talk the AntAgonizer into stopping her attacks on the town and fighting Mechanist. You also get her costume.
 * You can talk Fantasia into stealing Dukov's key for the You Gotta Shoot 'Em in the Head quest.
 * You can talk Agatha into giving you ammo to help you during the Agatha's Song quest.

If you are female:
 * You can talk the Ronald Laren in the Nuka-Cola Challenge quest into a threesome (He always seems to end up dead just inside the door to the Nuka-Cola factory if you do this).
 * You can talk Burke in Megaton into leaving with you and getting someone else to blow up the bomb, pay you double to do the job, or to give up on the bomb entirely.
 * You can talk Karl (during the Blood Ties quest) into giving you the password to Ian West's room.
 * You can talk Mechanist into stop fighting his nemesis, the AntAgonizer. You also get his costume.
 * You can talk Dukov out of his key without paying for it for the You Gotta Shoot 'Em in the Head quest.
 * You can talk Uncle Roe into organizing the trade caravans.

Overall, it is more beneficial to female characters as a lot more enemies are male than female (Talon company mercenaries are almost exclusively male). It is unknown how this perk carries through onto super mutants, as all gender indications are lost up mutation.
