The entire crew from the Campfires Fallout Equestria RPG.

The earth pony is Wire Storm, a not-Stable Dweller of many technical talents, an outgoing nature not being one of them.
The pegasus is Tutu, a self-professed wastelander who smells of many animals and whose only real talent lies in killing. Fortunately it is a seller’s market right now.
The diamond dog is Good Sister, a Lunar nun and wasteland doc - or meat artist as she would call it, whose cyber-tail helps with fine motor function her filly-sized hands normally would not allow.
The doe is Cherry Bomb, who began to grow antlers due to mutation, and seeks to reach princessdom through explosions.
