History.
Planetary Brigade: Origins.
A three-issue series title "Planetary Brigade: Origins" appeared in 2006–2007. The first issue showed the first time the team's founding members fought together, and the origin of their nemesis Mister Master. The second and third issues showed the backstory of Purring Pussycat, who reveals hidden depths that were not obvious from the earlier two-issue series. The flashback sequence in the second issue takes place before the original miniseries, while the third issue takes place afterward.
Trades and collections.
Both miniseries were collected in the 2007 trade paperback titled "Planetary Brigade". They were also included, along with the various Hero Squared series, in "Hero Squared Omnibus" (2017).
