lol j/k

There are 3 major belts WBC WBA and the IBF............ But the WBO is now seen as a legitiment world title belt aswell.
However if a fighter has the WBC, WBA and IBF belts.....he is seen as the undisputed champion.
But remember this ObiOne, it is not neccesarily the belt that determines how good the fighter is....You have to see who has he beaten and who has he lost too.
There are paper champions and there are true champions, just because they have the same belt dosen't mean that they are as great as each other. It's their opposition that counts.

Hope this helps

Someone else explain the Ring belt because frankly, i can't be bothered to type anymore. Ciao.
