The series debuted as a three-issue black-and-white limited series (the third of which featured a 33 RPM flexi disc with music and dialogue from the issue), followed by an eighty-issue ongoing full-color series. The black-and-white issues and the first six color issues were published by Capital Comics; after Capital’s demise, First Comics took over publication.
On the creation of the series: Baron noted that they had originally pitched a series called Encyclopaedias to Capital Comics, but the company rejected this, saying they were looking for a superhero title. Over a drink at a restaurant, Baron outlined his ideas for Nexus to Rude.
Nexus was entirely Baron’s idea. He even came up with the lightning bolt for the costume. All that we needed then was a name… a few weeks passed. Baron calls, and, without preamble, just says “Nexus.” We finally had our name.”
