#6 Triple H vs. Mick Foley
Triple H and Mick Foley began feuding for the WWE Championship in early 2000. It would be the Hardcore Legend's last WWE feud as full-time active superstar.
With the McMahon-Helmsley regime in full control, Mick Foley took exception to them and would frequently brawl with Triple H. This would result in Foley losing a 'Pink Slip' match to The Rock and being 'fired'. Foley would be reinstated the following week when The Rock would bring every superstar to the ring, demanding that Foley be reinstated or the entire roster would walk out. Triple H complied and when Foley returned, he demanded a Street Fight with The Game for the WWE Championship at the Royal Rumble.
For the feud, Foley would also stop performing as Mankind and revert to his far more violent Cactus Jack gimmick. The two would go onto have one of the best matches of the year and in Rumble history. Their Street Fight was incredibly violent and a heart racing kind of thriller. The bad blood wouldn't end here as the next night on RAW, Triple H granted Foley another Championship match for No Way Out and even let the Hardcore Legend decide what kind of match it would be.
Cactus Jack would decide on a Hell in A Cell match, which Triple H granted under the stipulation that he would retire if he lost, which was accepted. The two would have more memorable segments leading up to the match, including a caged Jack been driven out of the arena. The match itself would be another incredible Championship match and another highlight of both men's careers.
Naturally, Triple H won the match to officially end their feud, although over the next few months and years later, they would feud while Foley was in a non-wrestling role.
