5 WWE Superstars who beat The Undertaker but failed to become big stars

#4 Former WWE Intercontinental Champion Ahmed Johnson

Ahmed Johnson had the physical appearance to be a massive star in WWE, but he was still a bit green in the ring and didn't have much of a charisma.

The former football player made his WWE debut in July 1995 and although he won the Intercontinental Championship the following year, he never became a main event talent in the industry.

Despite that, he still scored a victory over The Undertaker. To add to the matter, he is also undefeated against The Phenom.

#3 Vladimir Kozlov

Vladimir Kozlov

Vladimir Kozlov is one of WWE's biggest failed experiments, which the company probably wishes it could rectify. During his early years, Kozlov received a massive push portraying a villainous Russian character and it looked like WWE was going to make him their next big heelish wrestler.

In one of the most shocking losses in WWE history, Kozlov defeated The Undertaker clean on an episode of SmackDown in 2009 just a few weeks prior to The Deadman's iconic match with Shawn Michaels at WrestleMania XXV.

Unfortunately for Vladimir Kozlov, things took an unexpected turn for him, as he was later placed in a comedic tag team with Santino Marella before getting released from the company.
