Born in Buguruslan, USSR and now fighting out of Los Angeles, California, Kiser’s nickname reflects his journey—an homage to the ancient Bushido code and the warrior’s path of solitude. With no masters to serve, Kiser stands as a modern-day ronin, stepping into the arena to carve out his own legacy. At 6’1” and 34 years old, he brings a commanding presence to the ring, with black fight gear that matches his stoic resolve.

Trained under Anatoly Kaminsky, his style blends traditional MMA techniques with an aggressive yet thoughtful approach. He is fearless, a quality that defines his performances, though he continuously works on enhancing his speed. Kiser made his name in mixed martial arts but now steps into the world of bare-knuckle boxing with a vision: to become a world champion and prove that even a lone warrior can stand above the rest. While this marks his bare-knuckle debut, his reputation precedes him as a powerful and dangerous fighter.

Fighting for Kiser is more than sport—it's a mission. Influenced by his upbringing and inspired by personal introspection, he sees each bout as a step toward greatness and self-discovery. His ultimate goal is to win every fight and etch his name in BKB history as a world champion. Off the canvas, Aleksei enjoys traveling and spending time with his wife. As he declares: 'Remember my name. I came to your organization to become a world champion.'
