Speakeasy published Atomika issues #1–4, from March–July 2005 (with the series consistently being the company's most popular title). In December 2005, however, with Speakeasy facing problems on multiple fronts, Atomika creator Sal Abbinanti split from Speakeasy to publish Atomika #5 and future issues under his own Mercury Comics label. After publishing issues #5–6 in short order, Mercury collected the first six issues into the trade paperback Atomika: God is Red.
