"outta the way, that bounties mine"
Gunrunner, the merc that's been all over. Most assume Gunrunner came from the Enclave as an outcast. Few have stuck around to find out he had in fact come from a stable. Gunrunner was quick to lose his pipbuck making him look like a simple wastelander. His wings kept him alive for quite some time, sometimes he was a slave, other times he was a raider. When his gang gets beaten he usually becomes a slave again, each boss liked the idea of having a pegasus in their gang which kept him around longer.
Spending many years in different gangs expanded his expertise in many areas. Eventually, his gang was ambushed by cannibals who passed him over at first which allowed him to escape. Gunrunner used his experience to become a mercenary or bounty hunter depending on his mood.
The merc is known for being rather snarky and quite enjoyed 'playing with his prey'. Gunrunner even managed to create a custom emp rifle that overloaded power armor. He uses this in great use whenever he gets at odds with the brotherhood of steel or whenever the Enclave comes downstairs.
What would happen if his somewhat repetitive routine was disrupted? What if he was taken on a journey that would change everything? would he demand payment?
