Kim made his international debut in 2005 at the World Cup in Seoul. Competing for the Republic of Korea, he quickly established himself as a formidable athlete. His right-handed technique and dedication to the sport earned him various nicknames, including Flaming Fencer and Inspector Gadget.

Notable Injuries and Comebacks

Throughout his career, Kim faced several injuries. He withdrew from the 2022 World Championships due to a back problem and sustained a thigh injury at the 2015 World Cup. Additionally, he injured his finger at the 2014 Asian Games and his ankle before the 2012 Olympics.

Superstitions and Beliefs

Kim adheres to three superstitions on competition days: wearing blue underwear, positioning his sword towards his opponent, and performing a ritual with water bottle lids. His sporting philosophy is encapsulated in his motto, "It's not a sword fight, it's a foot fight."

Awards and Honours

Kim's achievements have been recognised with numerous awards. In 2022, he received the Best Athlete Award from the Korean Sport and Olympic Committee. He was named Male Fencer of the Year by the Korean Fencing Federation in 2018 and 2021. In 2016, he was awarded the Order of Sports Merit Cheongnyong Medal.

Olympic Milestones

Kim's bronze medal in individual sabre at the 2016 Rio Olympics made him the first male fencer from Korea to win an Olympic medal in this category. He also won gold in team sabre at the 2012 London Olympics, becoming part of the first Korean men's team to win an Olympic medal in fencing.

Return from Retirement

After announcing his retirement post-2018 Asian Games, Kim transitioned to coaching at the Korean Sports Promotion Foundation. However, feelings of emptiness led him back to competition in 2019. Despite aiming for the 2020 Olympics, he now sets his sights on competing at the 2024 Paris Olympics.

Sanction and Resilience

In 2005, Kim was suspended for one year after testing positive for hydrochlorothiazide. He claimed it was due to sleeping pills taken for insomnia but was unsuccessful in his appeal. Despite this setback, he continued to pursue his fencing career, driven by encouragement from his late father.

Kim Roy's journey is marked by resilience and dedication. As he prepares for the 2024 Paris Olympics, he remains an influential figure in Korean fencing.
