#2 Lars Sullivan

Once again, if Black is still booked as a borderline face or anti-hero, then Lars Sullivan would make a perfect foil. 'The Freak' has been attacking anyone and everyone from legends like Kurt Angle and the Hardyz to newer talents like the Lucha House Party.
In the latest WWE NEWS, Sullivan needs a meaningful feud at some point, and perhaps he is the one to kick the hornet's nest that will be Black. The two squared off in NXT when Black was NXT Champion with Black getting the upper hand. This encounter could be brought up in a potential feud should they ever cross paths.
Black probably shouldn't start off in a feud with someone else relatively new to the main roster, but Sullivan needs to get his comeuppance at some point. What better way than with a 'Black Mass' kick?
Sullivan seems like he'd fight anyone but has been squashing superstars that are at the tail ends of their careers or who are a lot smaller than him. Black is neither of those things and would be a credible foe for Sullivan.
