The Galvan-Mechamorph War is a conflict of the Galvans and Galvanic Mechamorphs.
Start of a New Race
The Galvan saw great potential in the minerals lying on Galvan B. They wanted to do an experiment with them, but kid Xigor screwed things up. This experiment ended up creating the Galvanic Mechamorphs. When the Galvans discovered the nature and anatomy of the new species, some of them kept infants as pets, some kept adults as body guards, and some were used as assistants for scientists.
One day the Galvans discovered that one of the nanites in the Mechamorph's body was defective. They were dormant all that time, and when they when to remove the nanite, they accidentally activated it. It turned all of the Galvanic Mechamorphs into evil rebels. The Mechamorphs rebelled against the Galvan. Galvan's top scientists worked around the clock trying to fix them before it was too late.
The Galvans wanted to create an artificial life form that could gain back the control of the Galvanic Mechamorphs. But something went wrong in the DNA sequencing process and the creature was able to copy any ability upon seeing it.
8-year-old Noah traveled to Galvan Prime to sample a Galvan. He discovered Galvanic Mechamorphs and scanned them, too. The Matrix's scanning sequence deactivated the corrupt nanites.
End of the War
Noah left the planet, having solved the war. Though Copy Cat was still there. He destroyed Galvan Prime. Later, it was rebuilt. Copy Cat was set loose into the universe.
