Kane has been with WWE (in one way or another) from 1995 onwards. The majority of that time has been spent wrestling on Monday Night Raw, and he's unbelievably still one of the most active wrestlers on the brand today. His most famous Raw match would be the June 23rd 2003 Madison Square Garden bout with Triple H. It was Hunter's World Title versus Kane's mask, arguably the biggest stakes that ever existed in a Raw match. Triple H got the win, forcing Kane to remove the mask that he had hid behind for six years. But the majority of Kane's work has been in the mid-card. He's the perfect guy to put in a match that is really there just to fill time. He's got enough star power, and is good enough in the ring, to come off as watchable filler. That versatility, combined with his amazing physical longevity, has made him the most active Raw wrestler of all time. John Cena and Randy Orton will undoubtedly eclipse Kane's 431 matches (and overall total) eventually, but Kane will always be respected as one of Raw's most enduring stars.
