#2 Stone Cold Steve Austin

Stone Cold Steve Austin is without a doubt the greatest superstar in the history of Monday Night RAW (and possibly all of WWE), but he has also had a great career on SmackDown.
Austin appeared on many episodes throughout the show's history from 1999 - 2002, and some minor appearances afterwards, and gave us some of Smackdown's best matches and moments.

The majority of Steve Austin's best matches and moments from SmackDown came in 2001, during the Invasion angle. Austin wrestled several thrilling matches with Kurt Angle, Chris Jericho, Chris Benoit, Rob Van Dam and many more throughout the year and took part in some hilarious segments including several sing along's with Kurt Angle and The Rock, as well as his famous supermarket segment with Booker T.
Much like his appearance earlier this on the 25 Anniversary episode of Monday Night RAW, an Austin appearance would blow the roof off the building, bring in a lot of viewers and create another great memory in whatever segment they would use him for.
