#1 Samoa Joe

Even before Samoa Joe made his dominant presence felt in WWE in 2015, the heavyweight was in the public eye due to his epic career in TNA Wrestling. Now part of the McMahon-based company, Joe has done very well for himself, becoming the first two-time NXT Champion, as well as recently capturing the United States title.
Even a Google search wouldn't net results for much information regarding Joe's personal life, but he has previously stated that he has two sons. This tweet confirms that Joe is indeed a father, a fact that is unknown to most fans of WWE.

Over the past year, Joe has become a kind of evil father-figure in WWE, first addressing AJ Styles' family, and most recently taking on Rey Mysterio's son Dominic. We're not sure how we'd feel if our father could slap on a Coquina Clutch at a moment's notice.
