[the lexx] manhattan size kaboom

The Lexx is a bio-engineered, Manhattan-sized, planet-destroying, bioship in the shape of a giant wingless dragonfly, or to the remotely Freudian eye, a phallus. It was grown by ingesting organ collections from the protein bank on the Cluster, the seat of the Divine Order, for use by His Divine Shadow.

It was originally intended as the ultimate deterrent: the threat of a weapon that could instantly obliterate any planet would keep the remaining "Heretic" worlds of the Light Universe in line, and those that refused to capitulate would be summarily destroyed to reinforce the point. This plan was foiled when the crew commandeered it to escape from the Cluster.

The most important function of the Lexx is its ability to destroy entire planets with a single, high-powered blast. Its primary — and only — weapon is initiated by command from the captain only, followed by a highly dramatic sequence when the Ocular Parabola found on the surface of its eye tissue flips from a smooth surfaced dome into a complex array of satellite dish-like structures.

Huge amounts of yellowish-orange particles are released en masse from the array and focused by Lexx's nervous system to a point just above its mouth. Once focused, the particles burst into a massive, forward-moving, planar wave which expands ahead of the Lexx exponentially until colliding with an object of sufficient mass to disperse it, usually a planet.

The wave instantly vaporizes smaller ships without losing momentum. Though the Lexx is designed to destroy entire planets, it can fire less intense blasts to hit smaller targets; however, the smallest area it seems capable of destroying is roughly the size of an entire city.

So there!  :)
