A rather interesting debate has developed concerning the abilities of a certain Mr Herman Schultz, otherwise known as "The Shocker". The subject of the discussion is... "Is The Shocker a loser". The original Shocker profile on this page was rather damning of The Shocker - however a certain Mr Tim Eimiller lept from among the passive general audience to come quickly to The Shocker's defence. He claims that The Shocker's win/loss ratio against Spidey is as at least as good as most other villains.
Here is the Shocker's Win/Loss ratio as presented by Mr Eimiller.
Total score is 5 victories, 2 draws, and 5 defeats - a 50% success rate. I guess that's not too shabby against Marvel's greatest super-hero.
