Nicor class

The Battleship class was a type of Species 8472 bio-ship and was one of their primary warships used by their kind. They were crewed by a single pilot and were capable of naturally travelling at warp speed. They were made of the same bio-matter as the pilots themselves and, as such, were resistant to Assimilation by the Borg Collective. They were armed with a single powerful bio-pulse weapon that was capable of inflicting a great deal of damage on Borg vessels. (VOY episode: Scorpion).

The pilots had another form of weapon to unleash on their enemies which utilized their impressive telepathic abilities to unleash a wave of energy that drove the crew of enemy vessels mad. Infected enemy ships would attack anyone, even their former comrades and on certain occassions wuld lead to the crew activating the ships self destruct sequence.

Being one of the larger warships used by Species 8472, these organisms were not 'born' by Active Embryos but rather had to be drawn into the galaxy through a Fluidic Gate. (TNG game: Armada II).
