#3 Brock Lesnar - 504 Days (WWE Universal Championship)
Brock Lesnar has won the Universal Championship three times. He has not only won the title the most number of times but has held the title for longer than all other Champions combined. His first reign is the longest of all 3 reigns with over 500 days as Champion. His title reign started off brilliantly as he put up great matches against up and coming talents but the reign lost all steam at the end and ended in a lackluster way.
He won the title at WrestleMania 33 defeating Goldberg in one of the best matches on the card. The short 5-minute match was an explosive treat for the fans. He defended his title against Samoa Joe, Braun Strowman and Roman Reigns in Singles matches and in multi-men matches over the next few months.
But towards the end of his reign, he barely showed up to defend the title. WWE turned this into a storyline and Roman Reigns finally won the Universal Title off Brock at SummerSlam 2018 to end his reign at 504 days.
