#4 Ronda Rousey Debuted in WWE
Before 2018 no one would have even guessed that Ronda Rousey would make her debut in WWE this year. She was a major star in UFC, having a 12-0 unbeaten streak at the beginning of her MMA career and also making a career into Hollywood.
At Royal Rumble pay-per-view, after Asuka won the Royal Rumble match, then SmackDown Women's Champion Charlotte Flair and then Raw Women's Champion Alexa Bliss joined her in the ring. Suddenly music hits and out comes Ronda Rousey, surprising all the fans.
Charlotte Flair to return and wrestle a CURRENT CHAMPION?
She points at the sign of WrestleMania and then looks through all the three women in the ring, moves out and shakes Stephanie McMahon's hand, who was commentating the match. From there, she shows up at Elimination Chamber pay-per-view where Triple H and Stephanie McMahon approached her to sign her WWE contract.
As usual the contract signings never end without chaos, Kurt Angle exposed the real truth of Stephanie McMahon and Triple H, of how they were going use her after what she did with them at WrestleMania 31. This lead to Rousey crashing The Game through the table.
Rousey's first match was at WrestleMania 34 to team up with Kurt Angle against Triple H and Stephanie McMahon where she put up a great performance which was appreciated by the critics as one of the best debuts in WWE's history.
