Fiffe gained wider exposure in 2013 thanks to COPRA, a monthly series he has created and self-published since November 2012.[3] Despite its small print runs, COPRA has garnered acclaim from sites such as Comic Book Resources[4] and ComicsAlliance.[5] As the issues continued to sell out, compendiums reprinting three issues of COPRA at a time were released by Bergen Street Comics.[6]
In 2014, Fiffe began writing All-New Ultimates for Marvel.[7] In April, the first issue of All-New Ultimates was released, and COPRA returned with issue No. 13.[8]
