Man Mountain Marko!
I'm figuring the best way to show what Classic Kingpin was like is to show what he WASN'T quite like. Gonna take up this page for it, because it highlights some of everything mentioned. Real big strong guy. Strength feats. Smashing feats. Durability soak. Brawling/grappling contest with superhuman opposition, etcetera.
It should highlight why I don't quite feel comfortable giving Wade a nod over anyone with serum-based super-ability, striking feats, etcetera, why I think size REALLY matters when you're talking about very DIFFERENTLY sized "peak humans", and so on.
Anyway, this is going to take up the entirety of this page; you can skip this page and refer tomorrow if I get a chance to post to the URL and/or link version.
At any rate, without further ado, from Amazing Spider-man #73 and #75 ... Man Mountain Marko:
