Microman: Theology (2005)

A modern adaptation of the thrice-rebooted Microman series, this one geared for older readers (presumably who grew up on the original series from the 1970s). Seemingly set in an alternate universe from the original story, where instead of aliens, the Micromen and Acroyears are bio-engineered humans that have a cellular structure 1/18th the size of ordinary humans, and were followed by a terrible world war and pandemic. But with the discovery in a cavern in Peru, it becomes apparent that the world at large may not be as it seems... Originally serialized in Quanto Magazine in 2005, this unique spinoff series has unfortunately not ever been republished or compiled as of this posting (September, 2022). As such, no cover illustrations exist for this short series.
