Antonym first became well-known for his appearance at Pilipinas Got Talent, reaching the semi-finals with his impressive spoken word performances. He then decided to give battle rap a shot, competing in leagues such as Motus and gaining a few solid wins. In February 2024, he became part of FlipTop’s Won Minutes Luzon event, beating James Overman in a cerebral matchup. His big stage debut took place at the 17th edition of Zoning on the first of June. He may have lost against Negho Gy, but many still appreciated his poetic style and strong presence.
