What is "primortals"

Primortals (or typecased PriMortals) was a comic book series published by Tekno-Comix (later Big Entertainment) from 1995 to 1997. The characters and concept were created by actor Leonard Nimoy, who developed the idea for the series after visiting the SETI project. Science fiction writer Isaac Asimov was credited with providing additional concepts. The script of the debut issue of Primortals was credited to Kate Worley and Lawrence Watt-Evans with art by Scot Eaton and Mike Barreiro. Eaton and Barreiro illustrated the comic for most of its run, while the book was most often scripted by Christopher Mills and later James Chambers.
