Ghosts are a specie of Kilroy known as "Kilroy Ghosts" or "Moths". They're closest relatives are Luke the Spook and Flywheel (Although Luke and Flywheel are not Ghosts). After Luke the Spook began his life of crime; a large group of Ghosts joined him; and formed The Luke Mob . Not all the Ghosts went that way. The rest that didn't join signed up for the army or the Navy. Others took up other jobs. Unlike Luke the Spook who's gray; and Flywheel who's blue; Ghosts are white in color, and have a purple shading; but look exactly the same as Luke and Flywheel. You can distinguish a Ghost from Luke and Flywheel by their color. 

Self Defence

Ghosts are usually armed with B.A.Rs ; and sometimes a variety of different weapons.
