7. The Undertaker
WWE.comThe Undertaker is one of WWE's biggest stars ever. No question about it. Even non-wrestling fans have probably heard of him because he's been a part of WWE for 24 years. During the 1990s he was a key figure in WWE that feuded with a lot of bad wrestlers, but also the great ones like Hart, Michaels, Austin and so many others. Whether he was a kickass babyface or an intimidating heel, The Undertaker always knew how to generate a reaction from the fans. Once the brand extension stopped he made many memorable returns to Raw. There were some memorable moments like when he was challenged by Triple H to a WrestleMania match simply by staring at the sign or earlier this year when he stabbed a pen into Brock Lesnar's hand during a contract signing. The only reason he's not higher is because he was a Smackdown guy for the majority of the brand extension that was started in 2002, so he missed a lot of time on Raw.
