5 greatest first years of Superstars in WWE history

#4. 'Rowdy' Ronda Rousey

Rousey won the RAW Women's Championship at SummerSlam.

This is a hard one to call, as we as the WWE Universe are still experiencing the rookie year of UFC Hall of Famer, 'Rowdy' Ronda Rousey.

After leaving UFC as one of the company's most iconic stars, the Hot Rod would appear after the 2018 Women's Royal Rumble.

Rousey had her first match at WrestleMania 34, teaming with then-RAW General Manager Kurt Angle, to topple Triple H and Stephanie McMahon.

Unlike her fellow UFC star Brock Lesnar, Rousey makes continuous appearances on RAW, and had her first shot at championship gold at Money In the Bank.

Despite falling short then, Rousey would capture the RAW Women's Championship from Alexa Bliss at SummerSlam, just months into her in-ring career in WWE.

Now a bonafide WWE Superstar, Rousey will (presumably) be the headliner for the upcoming all-female WWE Pay Per View, Evolution, where she will face Nikki Bella.
