1. Samoa Joe
Samoa Joe has all the required ingredients to be a fantastic mystery partner this weekend. He's recognisable to some fans and obscure to others, allowing for both a sense of excitement and mystery. He's been building momentum in NXT, and is commonly regarded as an amazing in-ring talent. Most importantly, he has a valid reason to be included in the storyline - his heritage. As previously mentioned, family has been a key theme of the feud, and the fact that the concept of "family" doesn't necessarily have to involve blood relatives. Additionally, mystery partners usually work best when they carry a significant air of intimidation, drawing a crowd-pleasing panicked reaction from the heels. If Joe has any quality in spades, intimidation is surely it.
