The Peacemakers are a team of Public Domain / Open Source Characters originally assembled on the Free Universe Forum. Various creators contributed their characters and collaborated to create a interesting team that could save the universe, fight the bad guys, or just bicker amongst themselves.
The characters are Flux, Jenny Everywhere, Dr. Acacia, Astro-Man and Outworlder. Click on their names to find out more about them, or visit the team's page on the Public Domain Superheroes Wiki.
I based this living tribute faithfully on an existing image of them, though I took one small artist liberty: It was mentioned that Dr. Acacia and Jenny had a relationship in another reality, and I figured that maybe they continued in our own reality as well.
Flux and Dr. Acacia can be used by anyone without any license or author citations. The other three require the following license:
The characters of Jenny Everywhere, Astro-Man and The Outworlder are available for use by anyone, with only one condition.
