Shawn Michaels Wrestlemania 14 entrance. That was "Attitude." Entrance starts at the 3:30 mark in the video. Love the "whos' the fucking man!" he screams while walking down the aisle.
Hell fucking yes. I'd rep you again if it would let me, but honorable rep for now! The look in his eyes is scary (drugs I guess, but let's pretend it's purely attitude and intensity), and seeing him scream that still gives me chills. Best entrance ever, IMO.
Eddie Guerrero with the low rider like a boss
Edge with the smoke
RVD w/ pyro
Randy Orton Legend Killer w/pyro
DDP I loved the hand sign and the pyro when he dropped it
Scott Stiener's WWE entrance and theme with the lights, the over all feeling was cool
Thats all I can come up with right now, but I'm sure there is many others. Its a shane today most of the superstars have generic themes and entrances
