Steiner's one of my favorites of all time. I loved his character on WCW. Not because of the guy he was supposed to be, but because of the way he performed him. Normally, guys like Scott aren't exactly my favorites at all. But the way he does it, that alone is something to admire him for.
The greatest thing is his anger. It is so real. He wants to fight anybody, whether it's Kevin Nash, Hulk Hogan, Goldberg, The Rock, or some dude in the crowd, it doesn't matter to him one bit. His last entrance theme in WCW was the best by far. The police sirens, damn did it add up to his character.
He has a devastating persona, he is very sure of himself, and he never backs down from a fight. And when you're a referee, don't get too close, cause he'll beat you up and throw you out the ring. One thing he always did during his last title reign, is beating up every opponent after the match. Whether he won the match or lost it, he always went to grab his lead pipe to start whacking the shit out of those poor guys.
Oh and he has a record of kicking other superstars into the hospital aswell.
Knowing him, he would not come back during a PPV as if it was planned or something. He would just break into a show, clear the ring, grab a mic and tell people that he's around. He'd call on the first guy he would like to beat up and then he'd leave the ring again. Now in WCW, that match would take place the same night. But knowing the WWE, they probably won't do it like that.
The WWE did a totally different thing with the nWo aswell, so it wouldn't surprise me that things with Steiner wouldn't be going down like in WCW. So all I'd hope on is that he still doesn't give a shit about the company he works for, and that he still will go his own way.
