#1 Ronda Rousey (Win record: 100%)

Perhaps no-one has had a better rookie year in WWE than 'Rowdy' Ronda Rousey.
Debuting at the Royal Rumble in January, Rousey won her debut match in impressive fashion: teaming with Kurt Angle to defeat Triple H and Stephanie McMahon.
Opting to be a full-time Superstar, Rousey has won every match she has been in, with a record of 45-0.
Her biggest win arguably came at Summerslam, when she destroyed then-RAW Women's Champion Alexa Bliss to capture the title, defeating the petite powerhouse in mere minutes.
With such an outstanding record though, the question is now, who will be the one to break it?
Many are suggesting Becky Lynch, who was scheduled to face Rousey at Survivor Series but was taken out of the match due to injury, with the pair rumored to main-event WrestleMania 35.
