#1 Ronda Rousey

The winner of the 2018 Women's Royal Rumble match was not a surprise in itself. Asuka is undefeated in WWE / NXT, and so after her biggest rival Nia Jax was eliminated, it was only a matter of time before Asuka cleared the ring and took her prize of a title shot against either Charlotte or Alexa Bliss at WrestleMania 34.
The surprise, however, was the entrance and appearance of Ronda Rousey, the former UFC Women's Bantamweight Champion and now official member of the WWE. Coming out with Rowdy Roddy Piper's trademark t-shirt and leather jacket, Ronda smiled at the audience and made her way to the ring to point at the WrestleMania sign, and potentially tease a confrontation with Charlotte.
