#1 Dean Ambrose
Dean Ambrose returned in 2018 with a brand new look and attitude. After a brief reunion in The Shield, he would turn on his former Raw Tag Team championship partner, Seth Rollins. Since then their feud for the Intercontinental championship has reshaped the Raw brand. In addition, it has cemented the importance for mid-card feuds.
Now that Ambrose is no longer Intercontinental Champion (watch the video below), he has set his sights on winning the Royal Rumble. Interestingly in 2016, he and Triple H were the last participants. However, Triple H was victorious. Nevertheless, Ambrose has proven his worth at the Royal Rumble.
During the match, it is unpredictable what could happen. Therefore, Ambrose is highly suited. His outrageous and crazy behavior would greatly benefit his chances. With Ambrose winning the Royal Rumble WWE has a plethora of excellent WrestleMania match options. Just imagine Dean Ambrose versus AJ Styles, or perhaps Finn Balor.
