Cortex didn't create new mutants on his own up until Crash of the Titans where he discovered Mojo. All the mutants you see through the first to third game were made by either Brio or Cortex with the Evolvo Ray.

If you take Brio out of the story, you have Cortex with a faulty version of the Evolvo Ray and an idea that may never see the light. If you take out Cortex, then Brio likely would have just went on with some other evil plan. So overall, I see them both as the heavies.
