#5 The Rock Vs. Brock Lesnar for the Universal Championship

While I might be despised in abundance for saying this, there's no superstar that has a legitimate chance of facing the Rock than the Beast Incarnate, Brock Lesnar.
Despite his part-time schedule, Brock Lesnar's pull is extraordinary, and he is a major box-office attraction for shows like WrestleMania 35.
Considering that there is history between the two, with the Suplex City machine destroying the Rock at SummerSlam 2002 to win the WWE Championship, the Great One never returned for a rematch.
Bringing the former WWE Champion back to the frame for one more match could be enticing enough for the fans to be invested in, and while both the superstars follow a part-time schedule, this WrestleMania 35 main event smells like money.
Vince McMahon might be looking for someone to fill that huge spot vacated due to the Big Dog's absence, and booking a solid SummerSlam 2002 rematch at the Show of Shows could be a legitimate money-spinner.
