Oscar Sierra Quintero is a Colombian comic artist and cartoonist, who lives and works in Costa Rica. Mostly active under the pen name Oki, he is best-known for his comics based on Latin American myths and legends which he made for La Nación and The Tico Time. He is also an avid promotor of local comics in Central America through the non-profit organizations La Pluma Sonriente Internacional (1980) and La Pluma Cómic (2000).

La Pluma Sonriente & La Pluma Cómic
Oscar Sierra was born in 1953 in Barranquilla, the capital of the northern Atlántico department of Colombia. He moved to Costa Rica in 1979, where he founded La Pluma Sonriente Internacional in the following year. The association united local comic artists from Central America with the goal to develop and promote the local graphic humor culture. La Pluma has organized the annual Salón Anual del Humor y la Historieta La Pluma Sonriente in San José, and has also held exhibitions of locally produced comic book art throughout Central and South America, as well as in Spain, Portugal and South Korea. Under Sierra's supervision, the group launched the anthology 'Antología Humorística' (1982) during its first event, and also published the cartoon humor magazines De oreja a Oreja and La Cabra en Patines between 1985 and 1989. The group has furthermore participated in international comics and cartoon contests in Bogotá, Havana, Madrid, Quito and Rio de Janeiro. A division aimed specifically at comics was launched in 2000 under the name La Pluma Cómic. Among the other prominent members are artists such as Edmundo Anchietta, Rafael Campos Campos, Ronald Díaz Cabrera (Rodicab) and Ronald Lopez Aguilar.

Comics based on Costa Rican legends and literature
Among Sierra's own output is the series 'Mitos y Leyendas de Costa Rica' (1984-1991, later retitled to 'Mitos y Leyendas de Latinoamérica'). The feature offered comic stories based on local legends from Costa Rica and its surrounding countries. It first ran in the daily newspaper La Nación, and later also in the English-language The Tico Times. It was however cancelled by the newspaper's board of directors after a popular run of seven years. Several stories adapted by Oki were later collected in the book 'Leyendas Costarricenses en Novela Gráfica' (2011), which also featured stories based on local folk tales by Rodicab. In 2018 Sierra released the digital and print edition of the comic book 'Salir con Domingo 7', based on one of the stories from the Costa Rican literary classic 'Cuentos de mi tía Panchita' by Carmen Lyra. Sierra also served as graphic artist on 'Uvieta, El Musical', a multimedia project based on Carmen Lyra stories.
