In "DC One Million" #4 (1998), there is a group of super-powered animals living in the 853rd century (including a white horse wearing a version of the Superman S-shield) who were referred to as veterans of the Justice Legion of Super-Zoomorphs and were "led by Proty One Million and Master Mind" (the latter a possible descendant of the worm villain Mister Mind). "DC 1 Million 80-Page Giant" #1 (1999) introduced a group of super-powered animals in the 853rd century called the Legion of Super-Familiars. The story specifically says the team carries on the legacy of the Legion of Super-Pets and that there are many such legions on different worlds, all overseen by the Legion of Executive Familiars, led by Krypto-9.
