Before Storm, there was Butterfly. Butterfly, aka Marian Michaels, was a sultry Las Vegas cabaret singer by day and a superhero by night. The superheroine made her first comic appearance in 1971 in a supplemental issue of Hell-Rider #1. The issue was published by Skywald, who did include a proper copyright notice in the comics, making the issues public domain when released, due to copyright law at the time of publication.
There are no color images of Butterfly, but her rather sexy costume included a jetpack, and definitely didn’t hinder her when she need to bust our her superior fighting skills.
In Hell-Rider #2 Butterfly put her skills to use to fight a group of white supremacists.
Not much is known of Butterfly’s backstory. Unfortunately Hell-Rider only ran for two issues and Butterfly was never seen again.
