Cyborg has spent her entire career beating up nothing but undersized, unathletic, soccer moms. She has never once faced a C-level athlete, let alone an A-level athlete. Give an olympic gold medalist like Caster Semenya 6-12 months of MMA-training and Cyborg would be in for a rough night. She can't deal with that kind of speed, cardio and natural power. Cris would get manhandled.
