Zerocalcare

Michele Rech (born 12 December 1983), known professionally as Zerocalcare, is an Italian cartoonist. His pen name, literally meaning "zero limescale", was inspired by an Italian TV commercial jingle for a descaler product, and was chosen when he needed a nickname to quickly join a discussion on the Internet.

As of 2019, his books have sold over one million copies. His works were also adapted in other media, including the 2018 live-action movie The Armadillo Prophecy (Italian: La profezia dell'armadillo), based on the 2011 graphic novel of the same name, and the Netflix animated series Tear Along the Dotted Line (2021) and This World Can't Tear Me Down (2023), in which he also starred.
