The Lexx was planned to eventually be used to destroy all human-inhabited planets to make way for a new insect era. The design of the Lexx is credited to Brizon in Lexx 2.19 "Brizon". It is possible Brizon based it on the Brunnen-G's moth ships (one of which he possessed), which was used by the ancient Brunnen-G in the latter part of The Great Insect War. Because of this it is composed of both insect and machine components. Though, despite it being engineered part insect, it does not possess the Insect Essence itself. The Lexx's love of destroying planets is more attributed to its programming and its need to feed.
As a side effect of this organic design (whether intended or not), The Lexx has the ability to breed with other insects. This was shown when it found a mate while consuming the country of Holland. Despite appearing male (gaining a female personality when the sex change virus invaded the ship in Lexx 2.7 "Love Grows"), The Lexx did have the ability to give birth to Little Lexx, as seen at the end of Lexx 4.24 "Yo Way Yo".
The Lexx has a more highly advanced weapon system than His Divine Shadow's previous flagships. It also uses a different design of weapon, as the two previous ships utilized a highly amplified version of the Black Pack weapon system. This weapon system uses The Lexx's ocular parabolae (its insect "eyes") to fire a concentrated horizontal beam of energy (a ring of energy in the later seasons, though was shown to once again use the horizontal beam of energy during the destruction of Earth in season 4), which has the ability to destroy any planet (including anomalies like Fire and Water). The weapon system is not without limits, and was shown to be unable to penetrate the shell of the Giga Shadow when he fully resurrected. It is unknown if this applies to all insects, or just ones of a certain age.
The Lexx also (possibly intended) does not have an advanced intellect, even being called stupid on a few occasions. Despite this, it carries a high amount of information if required.
