erin go bragh is the name of a very mysterious pony. he's often seen around canterlot and whinnyville, though not many know where he lives. few dare to speak to him due to the many rumours about his actions, therefore many call him "shamrock" because of his cutie mark. "lucky" & "irish" are two other common names that are used by ponies who aren't familiar with him.
erin is an independent hitman. unlike a regular hitman, he is not empolyed by anyone and he decides the victims himself. he only kills criminals, and is therefore in a sort of grey zone with the law seeing as he does the police's job for them, but in an illegal way.
there are some ponies though, who have heard of him and what he does, and who actually appreciate him for it. they think he's doing the right thing by cleaning up the streets and making equestria a safer place. his fans refer to him as "the saint".
he wears golden horseshoes, mainly used as weapons but they also helped him fit in in the great city of canterlot when he first arrived. he also has a golden septum piercing and he wears golden beads in his mane. his tail is docked, and therefore very short.
