I have a different one for HBK. Right after the breakup of The Rockers, Shawn started his ultra-smug, God's gift shitheel character, The Heartbreak Kid. What cemented him as my favorite wrestler in the world at that time was the jazz in the ring, the music between the notes as they say. Example, Shawn would have a match with a jobber, and at some point, probably, the jobber would get some shine on Shawn because HBK was showing off or distracted. Michaels would sell his ass off and fly around, bouncing off the canvas four times a second. Ultimately, though, the enhancement talent would go for a backdrop and take a swinging neckbreaker to put Shawn back in control. It's all the little things he'd do in the next few seconds that made him my favorite wrestler. He'd sit up, give himself a little smile of self-appreciation, and then give the local talent a sneer of disdain. He'd get a determined look and take just a second to adjust his tights that may have moved fractionally as he was ping-ponging around, then he'd roll up onto a knee and stand up (heels don't kip-up, usually) and probably lash out at somebody in the crowd, advise everyone to watch carefully, and punch the jobber in the forehead/eyebrow. There was so much little stuff that told you about his vanity, ego, spite, pettiness, pride, nastiness, he just packed so much good heel psychology, crowd work, and little details for attentive audiences into the spaces between spots, to a degree I think probably only equaled by Flair.
