1.) Aleister Black
Everybody in the WWE Universe knows this wrestler from NXT. His entrance, attitude, style, brutal moves and wrestling remind us of The Undertaker. There is a high possibility that WWE will soon promote Aleister Black to the main roster because of his successful career in NXT.
I think WWE will not take too long to make his debut on the main roster. The NXT Championship match with Gargano is set up for NXT TakeOver: Phoenix before the Royal Rumble 2019 so there's high possibility of The Dutch Destroyer to make his debut at the traditional Royal Rumble match.
Aleister Black has lot of talent and potential to become a main eventer in WWE. With his fearsome attitude and exceptional wrestling skills he is the most likely one to make debut at Royal Rumble and can have a longer run in WWE in the weeks to come.
