The Borg are a cybernetic species, and whilst being Humanoid in appearance their bodies are implanted with large amounts of artificial mechanical enhancements which allow the to function as part of the Borg collective consciousness.

    The Borg have one goal - the assimilation of culture and technology - and this goal is striven for by one mind, making it all the more dangerous. 

    The Borg's collective culture is organized around a hive like hierarchy which stems from the Borg 'Queen' who operates like a regulator for the trillions upon trillions of drones, bringing clarity of purpose and order to form one voice. The Borg Queen embodies the collective, and it may be prudent to assume that without the Queen the Borg would cease to function as a whole and their culture would disintegrate - but that is not so. The Queen exists within the collective's subspace mind, her physical form is only a means of communication which other beings - such as Lieutenant Commander Data and Captain Jean-Luc Picard - can more easily relate to whilst in contact. This form is completely artificial, the organic tissue is mrerly engineered over a endoskeletal frame. It has only been reported twice and twice it has been destroyed, but her presence remains and the Borg go on.

    The Borg have no mercy, no emotions, they exist on one premise - that they will eventually assimilate everything. They do have a certain amount of reason, and have been known to negotiate when it was to their benefit, they are also, however, deceitful and arrogant and any concessions they make are quickly forgotten when they no longer serve the Borg's purpose. 

    The Collective is formed by the minds which it encompasses, these minds interact over a sophisticated subspace network, functioning co-operatively to achieve the continuous betterment of the species with maximum efficiency. Borg society thus consists entirely of this virtual interaction within subspace.
