Why did Kostya Tzyu change his name?

Konstantine is fairly common Russian name I think, I was watching this movie called "the beast" about a Russian tank crew stranded in Afghanistan with a psycho tank commander and one of the guys names was Konstatine. But I agree Konstatine sounds alot better than Kostya. However in Russian I think when using the Latin alphabet there is a Y in there so its spelled like Kostyantine or something. I saw it spelled that when when he was introduced in one of his amateure fights.

its obvious just cuz it has be to be a quick catchy name lots of guys dont fight with thier birth name Zab is really Zabdiel that shits just plain awsome so if i tuned pro id have to become Ab

He was afraid of Oscar De La Hoya. yo jack you should add oldgringo the rippuh to your sig. :D

Make one mistake and it will Kostya.....Corny I know but true. Haha, that was very corny :D Konstantine sounds very badass, he could be like, a boxer by day and devil exorcist by night! :) I know, that was corny also :D

I don`t think he changed his name legally only that for boxing means its easier to pronounce.

He was afraid of Oscar De La Hoya. thats what I was going to say... Is everyone positive that KT's original name is Constatine? I thought I read a couple of years ago that his birth name was Reggie Tszyu? I may be wrong but I doubt it.

I believe that Kostya is just a dirivative of Kostantin. You know, like Jim from James, John from Johnathan & Joe from Joseph. That's correct
