Stone Cold's 2nd glass shattering theme (he started using a slightly different one in 1998 than his first one in 1996)
Hulk Hogan's All-American theme
Goldust's theme
Ultimate Warrior's theme
Undertaker's original theme (from 1991-1994)
Shawn Michael's theme
Runner up: Jake Roberts's first theme. But I also liked the way his second theme started off with Jake saying "Trust Me" in a creepy way. Would have been perfect if they could have combined both into one theme.
