#3. Dean Ambrose

The Shield breakup, Dean Ambrose's heel turn and their reunion after Reigns' return from cancer recovery has all been a bit of a mess really. Now Dean Ambrose is allegedly on his way out of the WWE and isn't even scheduled to appear at WrestleMania.
However, his Shield brothers are both in matches. Roman Reigns is taking on Drew McIntyre in somewhat of a grudge match and Seth Rollins is taking on Brock Lensar for the WWE Universal Title.
Look who just shut down all of Tony Khan's critics! More HERE.
What if Dean Ambrose wanted to make his presence felt at WrestleMania and reinforce that he hasn't truly forgiven Roman Reigns and Seth Rollins for the things they did to him that led him to turn heel on Rollins in the first place. He even has two opportunities to ruin the matches for his former stablemates.
