The Evil BYDO
The Bydo were created by mankind in the 26th century to be used as weapons of ecological destruction against our enemies within the galaxy. Unlike conventional weapons of defense, the Bydo were conceived as limited range weapons with the purpose of destroying every ecological form in their path.
The Bydo were placed inside a container almost as large as the moon where they consumed everything and continued to evolve. A combination of physics, genetic engineering, and black magic resulted in man-made creatures of evil.
Mankind intended to send the Bydo through a wormhole to the enemy solar system to annihilate their planet. Everything appeared to be going as planned. However, there was a slight error and the Bydo became active in our own solar system. For 150 hours they raged until they were carried away to another dimension by a special weapon. It appeared that mankind in the 26th century was safe.
However, the Bydo were still alive and continued to evolve in another dimension. After wandering for what seemed like an eternity, they reappeared in the 22nd century to demonstrate their power against Earth.
Within the heart of the Bydo Empire, a cloning plant was discovered. It lies in a steam cleaned area inside of a gigantic computer which controls the the planet itself.
Not only did they multiply as life forms, but achieved mass production of mobile weapons systems. Thse instincts of destruction and the feelings of terror which they caused, prompted mankind to call them the Bydo Empire.
