ONE Strawweight Indonesian Tournament Champion Adrian Mattheis was born in the Maluku islands of Indonesia to a family of farmers. Leaving in search of a better life after surviving violence and riots, his family settled in Sorong. Fortunately, his parents supported his ambition to train in martial arts, and they enrolled him in karate classes.
He later met famed coach Zuli Silawanto while studying at a university in Jakarta, and Mattheis soon began to train for professional competition. He would make his ONE Championship debut in August 2016, defeating two opponents via knockout in the same night to win a four-man tournament and make an instant impact.
A young talent still at the beginning of his career, Matheis wants nothing more than to represent his coach, gym, and country well in the ONE cage. He has since dedicated himself to training, and he will not stop until he has become the next Indonesian martial arts superstar.
