Following his debut, Kane became a cornerstone for the company during the Attitude era in the late 1990s and early 2000s, defeating King of the Ring Stone Cold Steve Austin (described as the face of the federation of that period) for the WWF Championship in his first pay-per-view main event.
He played the role of several characters until 1997, the year in which he definitively adopted that of Kane, the masked half-brother of The Undertaker, with whom he alternately had a rivalry and teamed up in the tag team known as 'The Brothers of Destruction.'
Kane on The Undertaker
In an interview with Radio Times, Kane spoke about The Undertaker’s legacy: “When I came to WWE in 1995, things were terrible, frankly. He was the guy who was leading the charge into the Attitude Era and Steve Austin came along, The Rock came along, Undertaker was still in the mix.
We see Austin and The Rock as highs, but the reason the company survived to reach those highs was because of a guy like The Undertaker and he probably doesn’t get enough credit for that”. The Undertaker was one of the most prominent figures of the Attitude Era, a boom period in the company's business in the latter 1990s.
His character transitioned into a biker in the early 2000s, before returning to a refined version of his previous gimmick in 2004. The Undertaker is heavily associated with WWE's flagship annual event, WrestleMania, where he became known for The Streak, a series of 21 straight victories, and he headlined the event on five occasions.
He is also known for his pairing with storyline half-brother Kane, with whom he has alternatively feuded or teamed as The Brothers of Destruction since 1997. With Kane, he held the WWF and WCW World Tag Team Championships during The Invasion storyline.
Widely regarded as one of the greatest professional wrestlers of all time, The Undertaker is a seven-time world heavyweight champion in WWF/E, having held the WWF/E Championship four times and World Heavyweight Championship three times.
In October 2018, Kane and Undertaker started a feud against D-Generation X (Triple H and Shawn Michaels). At the October event in Australia WWE Super Show-Down, Undertaker faced Triple H in a singles match, with Kane and Michaels at ringside.
After the match, which was won by Triple H, Undertaker and Kane attacked both Triple H and Michaels, thus reunited the team. Throughout the following weeks, both teams had various confrontations, which then led to a tag team match at Crown Jewel.
At the event, Kane and Undertaker were defeated by DX. Following the match, Taker and Kane broke character and hugged one another in the middle of the ring. Both of them also did their signature arm pose together on the top of the ramp.
