#1. Roman Reigns
Roman Reigns' shocking in-ring revelation that he had Leukaemia remains one of the most stunning moments I've ever seen in professional wrestling. Reigns introduced himself with his real name, explained he was relinquishing the Universal Title and was going to battle cancer.
From that moment it was unclear how severe Reigns' leukaemia was, and how long he would be gone for, or if he would even be back at all. Leukaemia certainly affects different people in different ways and there are different types, so as a result it was possible that Reigns would never return to the ring.

But just five months later, Reigns made a miraculous return to Monday Night RAW to reveal his leukaemia was in remission and he was back earning a huge ovation from the crowd in what was one of the best feel-good moments in professional wrestling history.
Since then, Reigns has stayed out of the main event picture getting in feuds with Daniel Bryan and Erick Rowan after they attempted to kill him and King Corbin after Corbin mocked him with dog food.
