5 feuds that will define WWE in 2018

#4 Aleister Black vs. Adam Cole

The stakes will get higher.

Since their arrival at NXT TakeOver: Brooklyn III in August, the Undisputed Era has made NXT their playground. Their aim, they say, is to "shock the system," and they've done that without fail so far. The stable captured the NXT Tag Team Championship as the year came to an end, with Bobby Fish and Kyle O'Reilly dethroning SAnity.

Adam Cole will join them in wearing championship gold sooner or later, most likely the night before WrestleMania. His most probable rival after that will be Aleister Black. The "Ominous Man from Amsterdam" would serve as the perfect foil for the reign of the "Panama City Playboy."

In 2017, Adam Cole established himself as the top heel in NXT, while Aleister Black rose through the ranks as its most enthralling, enigmatic, and unlikely hero. Their full-on collision and the bitter feud is inevitable, and it would be best served as the headliner for TakeOver: Brooklyn IV.
