I was on the DC wiki and I found the article on Metahumans/Metagenes.
- "One of the Dominators discovered that some humans had a "biological variant" he called the meta-gene (also spelled "metagene"). This gene often lay dormant until a moment of extraordinary physiological stress activated it, and upon activation it would use the source of the biostress as a catalyst for "genetic change," resulting in metahuman abilities."
So...what does the Competetor want with metagenes? Could it be possible that they are trying to harvest or farm the metagenes in humans (thus the term meat) and transfer them or something? Use people as weapons against other aliens.
