#3. Roman Reigns - 2015-16

This is an addition on the list that feels like the odd one out. Especially since Roman Reigns didn't have too much popularity among live audiences in the United States of America in 2015, to begin with.
Seth Rollins was the undeniable star of 2015, but the first and last parts of the year were heavily focused on the push of Roman Reigns - something that backfired in a big way. While John Cena at least held a high level of popularity in 2005 by WrestleMania, fans seemed dead-set against the idea of The Big Dog as the heir to Cena's throne.
The more WWE pushed Reigns, the more it backfired. However, by December 2015, Vince McMahon decided to take matters into his own hands and feuded with Roman Reigns for an episode of RAW after TLC - leading to him winning the WWE title for the second time.
Surprisingly, Vince McMahon's presence was enough to make Reigns cheered in the same city that booed him for winning the Royal Rumble earlier that year - Philadelphia. He held a level of popularity for a few weeks, but it all went away by Royal Rumble 2016 a month later.
