Azerbaijan and Britain dominated the European taekwondo qualifier for the sport's Paralympic debut at Tokyo 2020, sharing the six available berths between them.
Four taekwondo players from Azerbaijan - which hosted the first-ever Para Taekwondo World Championships in 2009 - were victorious in Sofia, including Abulfaz Abuzarli.
In the men's K44 under-75-kilogram division, Abuzarli overcame Britain's Joe Lane 53-43 in a high-scoring final.
Lane had been down by five points when a timeout was taken 12 seconds from the end, and the Briton's attacking flourish was anticipated by Abuzarli, who extended his advantage.
Azerbaijan's Imamaddin Khalilov beat Israeli top seed Asaf Yasur to earn the men's under-61kg berth.
At over-75kg, world champion Matt Bush was in dominant form and beat Hungary's Zoltan Kiss 28-1 in the final.
Compatriot Beth Munro, making an international Para taekwondo debut, earned Britain a Paralympic berth in the women's K44 under-58kg.
Munro defeated Italian Sara Enea 68-6 in her only match.
"I still feel like I am in a dream world," 27-year-old Munro said.
"This is an achievement in itself but the aim is a medal in Tokyo.
"I don’t know what colour."
Azerbaijan's Royala Fataliyeva defeated Georgian opponent Lia Chachibaia to win the women's under-49kg spot, while Aynur Mammadova's victory in the women's over-58kg meant all four Azeri taekwondo players at the event in Bulgaria's capital qualified for the Paralympics.
Mammadova beat Dalia Santiago from Spain.
Britain's Amy Truesdale had already qualified for the Games in that class.
Taekwondo is on the Paralympic programme for the first time at Tokyo 2020.
