Harlem Eubank has been tipped for global glory after lifting his second successive British title.
The ten-year-old nephew of former world boxing champion Chris, claimed the ten-to-12-year-olds' kumite fighting crown at the British Federation Championships at Sheffield.
His coach Paul Simmons, a former European bronze medallist, believes the Brighton youngster has the potential to make the big time in a sport that has been dominated by Great Britain in recent years.
Simmons said: "Harlem is a natural with his movement and technique. I call him a rocket horse because he is strong and powerful like a horse and quick like a rocket.
"He has also got the right attitude. He doesn't get fazed.
"I see many fighters who are good technically but there is a problem with temperament. That is not the case with Harlem. He has such composure, doesn't have a big ego and wants to win all the time. He doesn't view being a twice British champion at ten as reaching the top.
"Harlem sees each contest the same, whether it is the first or final round, and after that he just moves onto the next competition. It is the mentality you have to have to win European and world titles.
"It's hard to say how far he will go because of his age but he seems to have all the attributes to go as far as he wants.
"Hopefully he might compete in the Olympics one day."
Harlem overcame Gary Thomas (London) in the final to follow up last year's success in the under-tens category.
Simmons said: "He kept his cool and did what he had to do to win comfortably. What makes his win more impressive is that he is at the bottom of his age group."
Eubank also helped his largely Sussex-based association Kicks to win a silver team medal.
Simmons said: "Harlem had about ten fights on the day and coped superbly. He might have come away with a second gold medal but a team-mate got the team disqualified in the final and they had to settle for the silver."
Harlem, a pupil at Middle Street, Brighton, said: "It felt good to win and I do like performing. I didn't get angry with my opponents, I just wanted to win. I like karate and train four times a week. But I do other sports."
Harlem won the 70m sprint at the Brighton and Hove Primary Schools Championships and he has had football trials with Withdean 2000 and basketball team Brighton Bears.
Simmons said: "We want to keep things balanced with Harlem because he's still so young."
Harlem, son of former boxer Simon, seems to have the family's sporting genes.
His mum Kim said: "Harlem seems very co-ordinated and exceptionally gifted at sport. I believe he'll succeed at whatever sport he chooses to do.
"He gets easily bored. Sport certainly gives Harlem a focus but he has always been a good kid."
Harlem was the only individual gold medal winner from Kicks, but four other youngsters from the association made their mark in Sheffield.
Sarah Alles, 17, took the silver medal in the individual lightweight competition for 16-to-17-year-olds. She also helped her team to gold.
Zara Preston, 16, from Heathfield, was in the winning lightweight team which was made up of players from outside Sussex Peacehaven's Aaron Pooley, 16, won a bronze medal in the boys' 14 to 15-year-old category.
Poppy Clarke, 13, from Hove, secured a team bronze in the girls' event.
