Interplanetary Shadows takes place in a vast and expansive universe, and not all of its characters and concepts were created by me. I’d like to thank those who have allowed me to use their creations to tell this story. No IP Infringement is intended, and I have been given permission to use them. These characters, concepts, and organizations are as follows:

• Black Hole Jack, Aster, Oid, the Black Hole Gang, the Orion Partnership, the Zandian species, and all concepts related to them were created by T. Alex Mihalich, unless otherwise stated.

• Killapter is a Patreon Cameo courtesy of Rockstad.

• The Anterian species were created by Timothy Ray.

• The Gridian species were created by Andrew Gabriel.

_{This page will update whenever a character not created by me appears in the comic, for the sake of avoiding as many spoilers as possible. It will also update when a new species not created by me appears in the form of background characters or named characters.}
