Is it Manny Melchor of the Philippines?
IBF World Minimumweight Champion in 1992

His total overall record was 38-35-6 with only 10KOs!

Is there any world champion that has a worse record than his?

Rickey Parkey, the IBF cruiserweight champ in 86-87.

22-20-0

Although he lost the remaining 16 times after being a champion.

Juan Polo Perez, IBF Super-Fly champion in 1989-90, record 46-46-4.

Alfredo Layne 15-12,12 KO
Kelvin Seabrooks 28-22,22 KO

Francisco Quiroz of the Dominican Republic...

This guy might be the worst champion ever?

Maybe worst record but not the worst belt holder. They threw him in with some really good opponents early on (three past or future belt holders, a couple of more who went on to fight for alphabet belts) and he mostly held his own but lost. He beat a longtime contender turned belt holder for a trinket, but he wasn’t good enough to beat the best. IMO guys like Bert Schenk who had a padded record and briefly held a WBO middleweight belt we’re far worse “champions.”

As for real champions, Leon Spinks might have the worst. He was 26-17-3. Lew Jenkins was 73-41-5.

The great George Dixon was like 75-35

Just looked up Bert Schenk's record and yes, that is one hell of a padded record against a load of no name boxers with losing records.

I guess the worst champion would depend on the criteria we're using here...
JB Williamson's record, although not the worst, shows that he was stopped 12 times in a final record of 26(10)-16. He beat 30-1-2 Prince Mama Mohammed to win the title, but looking at Mohammed's record shows that he had a massively padded record.
Williamson lost in his first defence to a Dennis Andries who went on to have a pretty decent career but at the time, wasn't held in the high regard he is these days (by some).
