#4 Otis
One half of Heavy Machinery, Otis has gotten much more popular than any other Superstar who made their way to SmackDown from NXT in recent times.
While Heavy Machinery was largely engaged in the Tag Tag Championship picture, Otis was seen as the breakout star, as the big man is loved by the entire WWE Universe.
Currently, Otis, along with his partner Tucker, is involved in a battle for love with Mandy Rose. He is going after the man who tried to destroy his chances against in the form of Dolph Ziggler.
The two men will meet at Wrestlemania on the second day, and we could watch their rivalry come to an end sooner than later. What adds to the intrigue is the fact that big revelations have already been made in their storyline.
Since the SmackDown Tag Team Championship picture is already a little crowded with The Usos and The New Day chasing The Miz and John Morrison, we could watch Otis become the breakout star chasing a singles Championship in the form of the Intercontinental Champion.
The babyface could do well against a heel like Sami Zayn and his faction, while Tucker can provide him the support that he needs to even the odds. Fans wouldn’t mind Otis becoming the secondary Champion as there is a lot of support behind him.
