What would I be?

I've seen topics on what real world or not-real world weapons should be in the game, but nothing about unique weapons. Post its name, effects, and optionally the backstory.

Here's one:

The Flyswatter (variant of a bat/Police Batton)
Melee weapon with bonus damage against insects.

Pity.

A pinnalce of weapon design, its a unique triple barreled Gauss weapon, similar to a Minigun.
Firing heavy DPU slugs at a fraction of the speed of light, it tears anything thats not a building apart.
Needing both slugs and MF cells to fire and its heavy weight requiring PA to use are its main drawbacks.

The last wielder was killed by the elusive deathclaw ironically called "Fool."

Ingnores DT and DR. High DAM, High ROF, Long Reload time, Needs PA to equip, Ammo is rare and expensive (but not limited) and is found in a deathclaw nest.

"furious rager"

a unique C-278 modified by a member of the whiteblood empire, it fires .308 rounds instead of .243 rounds, has a longer barrel than usual leading to increased accuracy, velocity and damage and does more fatigue damage over time (hydrostatic after-shock), however this gun does less direct fatigue damage and can only hold 8 rounds in it's magazine, instead of 12. the normal C-278 is a fictional gun which is based on both, the K98 and m1 garand, but is semi-automatic instead of bolt actionned and has a bigger magasine, designed to hold 12 rounds, it is built in the whiteblood empire's factories.

I see what you did there.
