Flak

 is a former slaver from Paradise Falls who now lives in Rivet City with Shrapnel. Together they run the Flak & Shrapnel weapons store in the Marketplace.

He is one of the targets for enslavement that Eulogy put a special bounty on. According to Paradise Falls' gatekeeper, Flak sold the slavers out to Rivet City in order to gain shelter there. Before enslaving him, Flak is unkillable. This ensures that there will always be at least one live target for Strictly Business.

Flak and Shrapnel share their store's inventory, so buying or selling from either one of them will update both of their stocks. This means that if Flak is enslaved by the player for Paradise Falls, Flak and Shrapnel's store will still be open. They consistently have a larger amount of caps than the other shops in Rivet City, making them prime sources of cash in exchange for unneeded loot.

Flak can also repair the unique Alien Pistol.

Appearances
 only appears in Fallout 3.

Bugs

 * If the player chooses to enslave Flak and then releases him from Paradise Falls he may be found back in Rivet City doing his usual routine. The problem is he is now missing his dialogue options. When interacted with, he will just have a line stating "You saved me from those bastards. I won't forget it.".


 * If Flak is enslaved and the player is not successful in subsequently removing the collar to free him, this will cause Shrapnel to disappear from Rivet City and no trading will be available.  Observed on PS3 version
