No idea what poor soul I'd pull from the past and drop into this underwhelming, shitty era.
But for the past, I'd give 'em Brock Lesnar.
Brock Lesnar would have been the absolute perfect heel against Hulk Hogan in the peak of his Hulkamania days in the 80's. That's why him defeating Hogan cleanly with a bear hug in the summer of 2002 was so cool, because back in the day, that would always be the spot where a huge monster wrestler would have Hogan in a bear hug and right when the third arm was about to drop, Hogan would suddenly pop back to life and fight his way to victory (Hogan was the one who made this spot famous, btw.) But here, his arm just drops and he loses. This ending would have been shocking back in the day. And this would have been a Wrestlemania main event, easily.
