4. CM Punk
CM Punk is the current World Heavyweight Champion and has shown no signs of slowing down, consistently delivering outstanding performances. However, given his unfortunate recent history with injuries, we never know when the 47-year-old would be forced to retire, and in that case, Gunther would be an ideal final opponent for him.
Gunther and CM Punk had an intense confrontation on the recent episode of Monday Night RAW, teasing a future feud between the two. They had a match previously at SummerSlam 2025, where Punk defeated Gunther to capture the World Heavyweight Title. Gunther would definitely be eyeing revenge for the loss, and it could make a compelling story for Punk’s final match.
