This comedian who knows how to extract the essence of the gag with unusual forcefulness and who uses absolutely recognizable graphics, began publishing in the Navarrese fanzine “Hamelin” in 1983. His first works as a professional appeared in the children's magazine “Ipurbeltz” and, shortly after , in Ediciones B magazines such as “Super Zipi”, “Zape” (Benjamín, 1990) and “Mortadelo Extra” (Casa Paco, 1992). Together with Joaquín Resano and J.J. Chas he made the album “The Enemy of the Whole World” (1992) for the humor magazine publisher “TMEO”. Apart from collaborating intensely in agencies such as “ComicUp” (with comics, storyboards, scripts or as a colorist), in the nineties he published in newspapers such as “Diario del Altoaragón”, “El Mundo” (Mini Mundo supplement), “Heraldo de Aragón” or “El País” (The Country of Temptations). He created series such as “Karolino” or “Ficciones Reales” for the satirical magazine “Mala Impression” in 1998, and the following year he became one of the permanent collaborators of the weekly “El Jueves”. There he began with the series “Los Chapas” (1999), for which he wrote the scripts, illustrated by José Luis Ágreda. With this artist, and also for “El Jueves”, they created four-handed series such as “Jaula Magna” (a kind of 13, Calle del Percebe in a university setting) in 2003 or “The Planet is Sick” (about ecology) in 2005. Alone, and still in “El Jueves created” the sagas “Urbano” (1999) and “Los Ilegales” (2006), a series that continues to be published. He became one of the regular authors of the current affairs sections in this weekly newspaper. In 1999 he wrote and drew the series “Los Retractilados”, a parodic revision of the comic universe that appeared in various comic magazines until 2003. As a colorist he collaborated on the book “Raúl y Andrea: a la Fuerza Ahorcados” (2000), written of Gomaespuma and drawn by Ágreda. Again with Ágreda he wrote and colored the series “Zoé in the fairyland” (2000-2002) for the children's magazine “Dibus”, and in 2003 he took over the scripts for “María Misteri”, a series illustrated by Javier Olivares and published in “Trezevents”. Between 2004 and 2006 he wrote the scripts for “Mister K” for Harry Pórrez (drawn by Enrique Carlos and Víctor Rivas) and “Multi-Man” (illustrated by Álex Sanvi). Between 2007 and 2012 he collaborated in the newspaper “Público” with a costumbrista series “Floor for four”, and with jokes about the cover topic. Since 2012 he has worked in the electronic newspaper www.eldiario.es with his current jokes. In 2013 he published “Palestine”, a comic that, in 20 pages, reflects in a simple way and without giving up humor, the Palestinian-Israeli conflict. In June 2014, a conflict arose with the publisher of “El Jueves”, RBA removed a cover that made reference to the change of monarch. Vergara, along with many other contributors to the magazine, considered it an act of censorship by the company and left his job. Together with several collaborators who also left the weekly, he founded the monthly digital satirical magazine “Pride and Satisfaction.” In June 2014 he also started drawing in Mongolia.
