Shooter

Shooter is Celty's pet name for her Coiste-Bohhar. Together they are known as the Black Bike and/or Headless Rider by the people of Ikebukuro. He has been with her for as long as she can remember, even during her days in Ireland.

Similar to Celty, Shooter doesn't have a head but still retains the ability to think. Shooter can change into three main forms; a pitch-black headless horse, a pitch-black headless horse with a black carriage, and a pitch-black motorbike without headlights. While in Ikebukuro, Shooter mainly sticks to the motorbike in order to fit in with the modern surroundings. In this form he is noticeably silent (lacking the sound of an engine) but lets out an occasional neigh (confusing passers-by) when he is anxious, confused, worried, pleased, etc. He appears to be covered by the same shadow-like substance that covers Celty and comes out of her neck. In the beginning of volume four it's stated that he combines dead horses and broken carriages to form his body. Shooter also has the ability to manipulate the "shadows", even using them to scale a vertical wall with Celty on his back.

According to Celty in the game, anyone can drive Shooter even if the rider can't ride a motorcycle. It was because Shooter is originally a horse, and as long as the rider can ride a horse, it doesn't matter whether the rider can't ride a motorcycle or not.
