There's no doubt that once the "exciting rookie" shtick begins to wear off, the WWE will waste no time in turning Balor heel. He is naturally a very dark character, speaking quietly and deliberately in the manner of a Kevin Spacey-type villain, providing interviews and promos which can be legitimately chilling. Combine this with his penchant for dressing up as comic book villains, piercing eyes, and role as leader of the unscrupulous nWo-style Bullet Club stable in NJPW, and you begin to see why Balor's true calling is as a top level WWE heel. Given the right opportunity to do so, he could be one of the most unique bad guys the company has ever seen.
