The Legends Sports Universe Boxing Federation's heavyweight title is the crown jewel of the LSUBF. From the initial pool, starting with champions prior to 1920 and between 2000 and 2010, the four fighters to qualify for the initial heavyweight championship tournament were Vitali Klitschko, Samuel Peter, Jack Dempsey and John L. Sullivan.

After Dempsey obliterated Peter with a second-round knockout, Klitschko found himself locked in a war with Sullivan that would end stunningly when Sullivan, up on two cards and even on the third in the 11th, is disqualified for a flagrant foul. Dempsey would become the first champion after stopping Klitschko on cuts in the 9th.

From there, the strap has had an eventful course.

Klitschko knocked out Sergei Lyakovich in his first defense, then took out James Corbett in the 15th round. But Klitschko would lose the belt to Sullivan by 9th round TKO before regaining the title from Sullivan later that year via a 6th round TKO, ending that trilogy for the time being.

The next year, Klitschko would defend twice, stopping Dempsey in the fifth and then Corbett in the 13th.

The stunner happened the following April, when Chris Byrd would cut Klitschko badly and shockingly won the strap. His reign was short-lived as his first defense was a rematch with Klitschko, and Dr. IronFist would eviscerate Byrd en route to a 7th round TKO to regain the title once again.

In the past few months, several terrific fighters who weren't in the LSUBF at its inception have worked their way into the Top 10 rankings as new challenges loom: Slots 2 through 5 are currently held by Max Schmeling, Jersey Joe Walcott, Rocky Marciano and Joe Frazier. That's quite a line of formidable challengers, to say nothing of the fact Dempsey has worked himself back to the Number One contender's slot, meaning an eventful next couple of years for Klitschko to say the least.
