#1 The Undertaker and Brock Lesnar
Brock Lesnar and The Undertaker had a lengthy feud on WWE TV throughout 2014 and 2015 which turned somewhat personal, but even though the two men have had their issues on-screen, it's reported that they are actually good friends off-screen.
The Deadman and Lesnar worked closely throughout their feud and it was Lesnar that The Undertaker actually chose to break his streak at WrestleMania 30 more than four years ago. Lesnar and The Undertaker were also spotted dining together the night before The Greatest Royal Rumble back in April, where Lesnar went on to retain his Universal Championship against Roman Reigns and Undertaker defeated Rusev in a Casket match.
