Ronaldo Artinic is a Brazilian voice actor, director, translator, and announcer. His professional name is derived from his family name spelled backward, a signature his grandfather used on paintings. He studied law while pursuing his passion for the dramatic arts, having passed the entrance exam for the University of São Paulo's School of Dramatic Art in 1977. His career in voice work began in 1988 when he was recruited from the university by the Álamo dubbing studio, where he would later become the well-known voice behind the studio's "Versão brasileira: Álamo" tagline. Over the years, he has served as a dubbing director at Dublavídeo and later worked in a similar capacity at Tempo Filmes.

Artinic is perhaps most widely recognized for his long-standing role as the character Aldebaran of Taurus in the Brazilian Portuguese dubs of the Saint Seiya franchise (known as Os Cavaleiros do Zodíaco in Brazil). He voiced the character in multiple entries across the series, including the original 1986 Saint Seiya anime, the 2002 Saint Seiya: Hades Saga, the 2014 CGI film Saint Seiya: Legend of Sanctuary, and the 2015 series Saint Seiya: Soul of Gold. His work in this expansive franchise also includes providing the voice for Geki of Ursa Major in several Saint Seiya productions.

Beyond this iconic role, he has lent his voice to a diverse range of characters in numerous other anime series. In Sailor Moon, he voiced Malachite and additional characters such as a reporter and an engineer. He is known for the role of Ryoya Komori in the supernatural horror series Ghost Hound. His other notable anime roles include Ashley Links in Solty Rei, the narrator in Excel Saga, and Dodoria and the narrator in Dragon Ball Z. His work also extends to live-action dubbing, with a role in the Japanese series Kamen Rider BLACK.

Throughout his career, Artinic has frequently collaborated with the Álamo dubbing studio. One of his recurring professional partnerships is with the Japanese voice actor Fumihiko Tachiki, whose performances he has dubbed for the character Ryoya Komori in Ghost Hound and the narrator in Excel Saga. A significant achievement in his career is his role in Saint Seiya: Legend of Sanctuary, a high-profile theatrical film that featured a new cast for the Gold Saints, further cementing his association with the character of Aldebaran.
