Reverse the roles and take Iron Solomon out of the confines of Grindtime safety where the d!ckeating and c*m guzzling runs rampant (and you can clearly see it all throughout the battle, which makes it look one-sided when it really isn't), then you have a completely different story.
Iron did have a couple of corny antics in there, but he would not do that s**t in URL. He would switch it up completely, and he probably would have the URL crowd going crazy. Reverse roles and put them in that type of environment, the bars would be completely different. Iron would still probably beat Ness.
Anybody who thinks Iron is just "another corny Grind Time rapper" needs to watch his old battles.
