Monster Allergy is an Italian comic book series created by Alessandro Barbucci, Katja Centomo, Francesco Artibani and Barbara Canepa of Sky Doll. Barbucci and Canepa had previously co-created the W.I.T.C.H. comic series. Monster Allergy lasted 29 issues; however, it is still in the course of reprints in newspaper stands on the 13th of every month. In 2008, Barbara Canepa stated that she and her co-creators gained back the copyright to Monster Allergy after its first publishing run.
