Shooty and Bang Bang

Shooty and Bang Bang are Blagulon galactic policemen.

They pursue Zaphod Beeblebrox to the planet of Magrathea, whereupon they proceed to shoot at him. This results in a hyperspatial field generator exploding and throwing Arthur Dent, Ford Prefect, Trillian and Zaphod forwards in time to the Restaurant at the End of the Universe.

Give yourselves up now and let us beat you up a bit.
Bang Bang

They claim to be well balanced and caring, while gratuitously shooting everything in sight. Bang Bang agonizes for hours to his girlfriend about gratuitously shooting everything in sight, whilst Shooty writes novels, in crayon. None of them have been published yet.
