Fiends

"Pack of drugged-out killers. They're addicted to every stim, every pill, every psychoactive enema on this fucked-up Earth."

- Major Dhatri

The Fiends are a local raider gang operating in west Vegas in 2281.

Aftermath and Destruction
With Motor Runner's death, along with his lieutenants, the remaining Fiends were left to pick up the scraps and somehow rebuild a gang. Their business allies ended their relations, with even the Legion electing to stop supplying the Fiends. Without coordination, the various groups began attacking one another, leading to even more destruction amongst the Fiends. Several groups left to raid other parts of the Mojave, while the Techno Fiends claimed victory in Vault 3.

The Techno Fiends were led by Bobby the Butcher and the massive Techno Fiend, who wore salvaged power armor. Bobby was a brutal and crazed ruler, constantly launching assaults on Westside using laser weapons stolen in a few caravan raids, along with kidnapping any unlucky settler. This resulted in Red and his companions returning to clear out Vault 3 once more. Vault 3 hadn't even been cleared of the dead bodies from the early attack when Red and company arrived. Bobby and the Techno Fiend joined Motor Runner in having Vault 3 as their tomb.

The remaining Fiends west of Vegas rallied under the "fake" Techno Fiend, who claimed to be the same enforcer and hadn't actually died in Vault 3. Using advanced armor, the Fake Techno Fiend ruled from Duckwater Cavern, though he only ruled over the shattered remains of the raiders. Red and his companions tracked the Fiends to the cavern and exterminated them as well, ending the Fiend threat in west Vegas.

Other groups were tracked down and eliminated. The NCR hired the Bloodbound mercenaries to destroy the Scrappers on Highway 168, and Red and the NVPD eliminated the Brahmin Boys in a shootout at a Poseidon Gas Station on Highway 95.

Few Fiends remained, with most succumbing to withdrawawls without a steady supply of chems. Others joined organizations such as the Slaver's Guild or the Sydicate, though they too would soon end up dead when Red went after those organizations.
