#2 Aiding a Bullet Club Alumni
Kenny Omega became the leader of Bullet Club after Finn Balor, Karl Anderson and AJ Styles left for WWE. Now that Omega is rumored to leave NJPW for WWE too, expect him to debut in a segment involving an ex-Bullet Club member. Omega joined Bullet Club in November 2014, and wasn't a part of the faction while Balor served as the leader. However, Omega was a part of the Club under Styles' leadership. In fact, Omega was the first one to attack Styles on his final night in NJPW.
Kenny Omega can arrive in WWE by coming to the aid of either AJ Styles or Finn Balor. Omega could then either form a short-lasting team with them, kick-off his feud with them or simply move on to other story-lines after aiding them. However, a memorable debut would be him coming to the rescue of a former Bullet Club leader.
