#1 Kassius Ohno

Ok, so Kassius Ohno is surely going to be a complete stranger for most of you. The reason is that this Superstar previously worked as Chris Hero and now works in NXT which automatically cuts off the number of fans who could recognize him.
Ohno started working for WWE in 2011 but left the company in 2013. According to former WWE writer Kevin Eck, Ohno, along with Rollins and Ambrose, was going to be in The Shield. However, the plans were changed and Reigns replaced him.
Cody Rhodes' uncle is a WWE Hall of Famer. More details HERE.
So this automatically creates some kind of history of him with The Shield. Ohno currently works in the UK division of NXT but in future, he could become the one to join Roman Reigns and Seth Rollins in a group.
I know that WWE can't build another Shield but at least, they could create a brand new stable which will outperform other teams in this company.
