Got two new riddles for you guys...

Ike Williams by chinchekked
A) My manager wasn't the nicest of guys. If you even dared blink he'd take your money. Going thru the list of my opponents is endless and the guys I beat forget it I have the who's who of that era. I picked up my first major title from one of Mexicos finest at that time. In between my title defenses I lost and won a few non-title bouts but that meant nothing back then. I beat the likes of a durango puncher, a cat and as bad as it sounds a child. Some of my fights were fixed but I had no choice. What wasn't fixed was the onslaught I laid on a dandy the first time we met.
Hint1: I became champ in '45 but became undisputed in '47.
Who Am I?


Lennox Lewis by palmerq
B) From the start I was destined for great things. I medaled but not for my birth country. I did things the right way and fought to the top. I beat a French man for my first title. My first big test was against a comeback kid but I took his 0. Not even one of the strongest men could stop me I was on a roll. When I won my first world title I did it because I knew how to detonate him. But I was quickly bucked off my title. It's okay I got it back and kept it for 3 yrs.

Who Am I?
