When Glenn Jacobs’ WWE career first began, he couldn’t find the right gimmick. He first had the Dr. Isaac Yankem gimmick in 1995, which didn’t last long.
The following year, he would portray an ex-WWE star.
After Diesel left the WWE to join WCW in 1996, Vince McMahon still had ownership of the gimmick. He used that advantage to get a buzz going.
Jim Ross announced that Diesel and Razor Ramon, who also left for WCW, were returning to the company.
When the returns were revealed, they turned out to be fakes. Ramon and Diesel were portrayed by other people who were neither Kevin Nash nor Scott Hall.
Glenn Jacobs was one out of the two men that portrayed the new versions of the characters.
Jacobs portrayed Kevin Nash’s Diesel character, and the fans didn’t like what was happening. The gimmick didn’t last long, and it was dropped in early 1997.
Jacobs returned to television in October with his most successful gimmick: Kane. At that year’s Bad Blood PPV, Jacobs debuted as Kane, alongside Paul Bearer, to attack The Undertaker.
This new character Jacobs was portraying was darker than his past two gimmicks. He was more dominant, never spoke, and wore a mask. The context of his character was that he was The Undertaker’s younger brother who had been left for dead in a fire.
Now scarred by that event, Kane was brought in by Bearer, his father, to get revenge on his older brother.
Throughout the years, Kane's character changed a lot. He started to speak more and even interacted a little with the crowd. The character went through bigger changes in 2002, when he switched from a mask that covered his full face to one that showed his chin and mouth.
Not only did he have a new mask, he also had more human-like attributes. He spoke more, interacted more with the fans and tag team partners, and even had a few comic moments.
In June 2003, the masked-Kane era came to an end. After losing a match to Triple H on Raw, Kane was forced to remove his mask. This was the first time people saw Jacobs’ face since the Kane character debuted in 1997.
From that point on, Kane became a more dominant monster and attacked anyone that got in his way. On the night he removed his mask, he attacked his tag team partner Rob Van Dam. During an interview with him, he even attacked Jim Ross and set him on fire.
Linda McMahon and Eric Bischoff were two authority figures that Kane targeted. Shane McMahon, who was out to get revenge on Kane for attacking his mother, also was attacked by the Big Red Machine on several occasions. The feud between both men ended at the 2003 Survivor Series. After Kane won the match, he went on to help Vince McMahon bury The Undertaker alive.
The mask-less Kane’s dominance fizzled out after he lost his match at WrestleMania XX to the returning Undertaker. Kane showed his dominant side at times, but he wasn’t the monster he had been before. When he finally realized that, Kane knew what he had to do.
On the December 12, 2012 edition of Raw, Kane returned to television. He hadn’t been on Raw or Smackdown since he had been injured by Mark Henry. That night on Raw, Kane made his entrance wearing a metallic mask.
After he attacked John Cena, Kane removed his metallic mask to reveal another mask underneath. The second mask was modeled after the version he wore from 2002 to 2003.
Kane had found a way to become the monster that he used to be. Currently, Kane still wears his mask. Though his dominance has once again calmed down, his dark side appears every once in a while.
Though nothing could bring back the energy, dominance, and excitement that the character had in the late-90′s, Kane pulls out a few tricks when he can.
