40. Cris Cyborg
Few women incite as much fear as Cyborg. The Brazilian MMA fighter is one of the most dominant female athletes ever. Her imposing physique and ferocious skills made her a ruthless opponent. In 2o18, she lost a title fight against Amanda Nunes after her fellow Brazilian knocked her out. It was a changing of the guard moment but fans wanted to see the rematch (via MMA Fighting).

However, they never got it because Cyborg left the UFC. The promotion failed to build a featherweight division around her during her tenure as champion. She also had a poor working relationship with UFC president Dana White. In the end, she decided to test the waters and make as much money as possible. Cyborg signed a new deal with Bellator and killed off hopes of a Nunes rematch.
