Bydo

The Bydo were originally bio-engineered as weapons sometime during the 26th century. They were placed in an orbital facility the size of a small moon where a combination of natural evolution, genetic tampering, and "black magic" (psionics) changed them into virulent germ-warfare agents.

The facility was driven into a wormhole to an enemy planet in a neighboring galaxy. The Bydo parasitized the inhabitants and their technology, and became active in the Milky Way.

The Bydo organisms were eventually rounded up and tossed in an alternate dimension. They escaped and returned, three centuries before they were actually created to make war on their creators, as all Frankenstein-like monsters seem to do. Although most low class Bydo seem to be mere sarvage beast, the Bydo as whole race are sentient. They produce many forms of mechanical weapon during long conflict against humanity.

The Bydo eventually wiped out from universe in their last war against human, the Operation Last Dance. As Bydo core facility, the womb, is destroyed by anonymous pilot in R-99 Last Dancer fighter.

Forces
Forces are "tame" Bydo organisms that can attach to synthetic vessels to add their energy to the vehicles. They are used by both R-Type pilots and Bydo starfighter organisms. Forces are larval Bydo creatures encased in an indestructable force feild generated by bio-energy, and controlled through rods. A smaller type of force, called a "Bit", is the result of attepting to reverse-engineer them using human biology to generate the feild-a highly controversial project that never got much farther than prototypical stages.
