Shotgun is an experienced soldier with extensive Special Forces and commando experience. Hes an expert marksman with pretty much any firearm, and quite fearless.
Weapon: Shotgun's preferred weapons are customized automatic shotguns loaded with specialty ammunition such as "shredder" rounds and high explosive shells. He routinely carries a pump shotgun and a pistol as backup. He also carries explosive spikes that are similar to a rifle grenade. Other weapons he has been seen with include a sniper rifle and a harpoon gun.
J.R. Walker was once a Special Forces soldier in the United States Army. Later, he became an assassin working for the CIA. When he was first seen, he had been hired by the director of a top-secret government lab working in genetic research. An animal rights activist had just hit the farm under which the secret lab was operating, documenting the inhumane conditions of the animals before freeing them.
Armed with a brand new and very expensive shotgun-like weapon, he tracked down the activist, Brandy Ash. However he soon realised that she was operating along with Daredevil.
