#2 Finn Balor
One of the biggest achievements of Undertaker's career is to portray a supernatural gimmick to perfection for almost three decades. Finn Balor's Demon King persona is the closest thing we have right now to the Undertaker's Deadman gimmick. WWE and Balor have done a great job in protecting this gimmick till now.
This feud will lead to a thrilling storyline between two supernatural characters and will bring shades of the classic Undertaker we haven't seen a while. Finn Balor recently stated in an interview with Inside the Ropes that Undertaker and Brock Lesnar are two of his dream opponents.
While Balor did earn the right to face the latter for the Universal Championship at Royal Rumble, a match with The Deadman is still a little too far. The win could prove to be a huge boost for the career of Finn Balor, who could be the next face of the company.
