Mantra made several appearances in various Ultraverse comics. In addition to her own series, she also had a miniseries (Mantra: Spear of Destiny), a spinoff miniseries (Lord Pumpkin/Necromantra), and numerous guest appearances in other books. Stealing shamelessly from Ultraverse Year One and Ultraverse Year Two, this section notes any Mantra-related appearances and when possible, summarizes the stories in those books.
The issue summaries also have scans of their corresponding cover images; however, if you're looking for a fast way to see all of the covers in one location, they're also on display in the "Pictures" section.
(Note: This section is still somewhat under construction at the moment, as some stories haven't been added to the list, and others don't have complete summaries just yet. I'll round out this section more in future updates.)
