ANTONIO SERRA was born in Alghero on 16 February 1963 he made his first appearance in the world of publishing and fiction in the late nineteen-seventies, when he became the editor of the journal for science fiction enthusiasts "Fate largo". In 1982, at the "Il Circolo" Cultural Center of Cagliari, he met Michele Medda and Bepi Vigna, together with whom he would later set up the group that has become known in cartoon literary circles as La Banda dei Sardi [The Sardinian Gang].Sharing a common passion for comics, the trio joined the "Bande Dessinèe" (together with other future authors such as Vanna Vinci and Otto Gabos), subsequently becoming professional writers in this sector, with some of the ideas they had created for Martin Mystère being scripted by Alfredo Castelli. Still working together, Medda, Serra and Vigna then created further scripts for the archeologist detective and also some for Dylan Dog. Finally, after working together on the Nathan Never and Legs Weaver project, they devoted their efforts separately to writing the scripts of the individual episodes. Serra is also on the editorial board of these two series, to which the series devoted to the Agenzia Alfa has been added. In 1999, the publisher Sergio Bonelli approved Serra's proposal for a "new" character. Thus Gregory Hunter (once Gregory Hammer, created at the time of the "Bande Dessinèe") has arrived on the newsstands in 2001, presenting himself as a classical hero who heralds the revival, after years of absence, of adventure with a capital "A". During the summer of 2005 a project that will become Greystorm (created with Gianmauro Cozzi) is started. This twelve issues miniseries hit the shelves in October 2009.
