Who was I?

This is a fun thread...first two stumped me to be honset with you...got the third one.
Fourth one has me stumped again...damn.

 

tony demarco.

 

tbh the only names that came to mind were elorde and demarco due to the stoppages in the same round.

 

I am not a hall of famer, but I've defeated a couple members.

I am most famous for going 2-1-2 against one well known hall of famer.

You can tell a certain "tough man" that I am the " real king..."

Who was I?

 

lol, forgot this is classic forum and not the lounge

 

I was afraid if I said too much, I would make it too easy.

Butterbean has been referred to as the King of the 4 rounders. The person I mentioned actually beat top notch oppenents in 4 round decisions.

 

I was a middleweight champion, and a fairly good one at that. I defeated a few all time great fighters, and am nicknamed after a natural phenomenon. In the last 2 fights of my career, I was eaten alive by a man with a big cat's name.
Who am I ?

 

Fat Willie Meehan. Jack Dempsey is the foe he beat. Do I get money lol.

 

I am an ESB poster, who likes classical fighters. Mr. Magoo has nabbed one of my former avators. Who am I???

Meehan was correct, Dempsey1238.
