Clarisse Agbegnenou of France beat defending champion Tina Trstenjak and avenged her defeat to the Slovenian in the final of the Olympic Games as she clinched the under 63 kilograms title at the International Judo Federation (IJF) Suzuki World Championships here.
Agbegnenou sealed her second world title after the Rio 2016 gold medallist was given three shido penalties during the final.
Germany's Alexander Wieczerzak secured the other title on offer today as he overcame Italy's Matteo Marconcini by ippon in the under 81kg final.
They were surprise finalists in a field which also included Russia's Rio 2016 gold medallist Khasan Khalmurzaev and defending champion Takanori Nagase, who was unable to maintain Japan's near monopoly of the event so far.
Agbegnenou, last crowned world champion at Chelyabinsk in 2014, signalled her intention from the start with a series of commanding performances.
The 24-year-old hardly spent any time on the tatami in the preliminary rounds, winning her opening bout against Israel's Inbal Shemesh of Israel by scoring an ippon after just seven seconds.
Mungunchimeg Baldorj of Mongolia, her opponent in the quarter-final, failed to provide any resistance and was beaten in 14 seconds by Agbegnenou.
Agbegnenou reached the last four by defeating Agata Ozdoba of Poland in a golden score period.
It was over to Trstenjak, the defending Olympic, world and European champion, to set up a Rio 2016 rematch.
The Slovenian duly obliged by battling past Yang Junxia of China, also in a golden score period.
Agbegnenou started the final the better of the two competitors and quickly seized control.
She was the only judoka offering anything in an attacking sense and slowly the shidos began to count against Trstenjak.
Trstenjak was unable to find a way past the stern defence of her opponent and was given a third penalty, resulted in automatic disqualification.
She had few complaints and the win for Agbegnenou was no less dominant than her rapid victories by ippon in the early stages.
"I am really happy, it was a tough match and it was really hard to win this fight and to win this World Championships," Agbegnenou said.
"I cannot find the words for my happiness, I just barely believe that I am the gold medalist here."
Baldorj recovered from her quarter-final loss to the Frenchwoman by securing the bronze medal, Mongolia's fifth medal of the Championships, by defeating Yang.
Ozdoba overcame European Games gold medallist Martyna Trajdos of Germany to join the Mongolian on the podium.
Wieczerzak also impressed during the preliminary rounds and stunned Khalmurzaev on his way to the gold medal match at under 81kg.
The German, whose previous best result came when he earned European Games bronze medal in Baku in 2015, was not among those tipped for glory before the event and his run to the showpiece contest was hugely unexpected.
The same was the case for Marconcini, beaten to the bronze medal by Sergiu Toma of the United Arab Emirates at Rio 2016.
Both athletes went on the attack early on but it was Wieczerzak who proved strongest and who scored the match-ending ippon four seconds before the halfway stage to claim his maiden world title.
A raucous home crowd were denied the chance to see a Hungarian judoka step onto the podium as László Csoknyai lost to Iran's Saeid Mollaei after a minute of their bronze medal encounter.
The other bronze medal on offer in the category was sealed by Khalmurzaev, who ensured his World Championships debut ended with a medal as he beat Uuganbaatar Otgonbataar of Mongolia.
The event in the Hungarian capital is due to coninute tomorrow with action in three weight categories - under 70kg, under 78kg and under 90kg.
Rio 2016 Olympic silver medallist and three-time world champion Yuri Alvear of Colombia is the favourite at under 70kg as she arrives at the event undefeated this year.
The under 78kg competition could come down to a showdown between two Olympic medallists and former world champions as Mayra Aguiar of Brazil and Audrey Tcheumeo of France are expected to battle for the gold medal.
World number one and European champion Aleksandar Kukolj of Serbia is the number one seed in the under 90kg division.
