#2 Lars Sullivan

Lars Sullivan is being built up as NXT's Braun Strowman, an unstoppable big man who lays waste to all those who dare to set foot in the ring. He, unfortunately, racked up some tag-team losses when he would constantly attack his tag-team partner after losing, building up his vicious character.
But when he ditched having a tag-team partner and entered the singles competition. Lars truly started dominating, defeating a veritable who's who of NXT Superstars. Alfred Watkins, James Drake and Ricky Martinez couldn't stop him together, No Way Jose and Oney Lorcan couldn't stop him and neither could Danny Burch or Raul Mendoza.
At the moment it doesn't look like anyone can stop Sullivan, although Kassius Ohno looks set to be the next NXT Superstar to try. However, I don't fancy his chances of ending Sullivan's undefeated single's streak.
Becky Lynch has been challenged HERE.
