The crossover series DC One Million in 1998 indicated that in the 853rd century a version of the team operates called the Justice Legion of Super-Zoomorphs. A follow-up story revealed that the universe of the 853rd century is protected by many teams representing the Legion of Super-Familiars, all of which are overseen by the Legion of Executive Familiars. It is unclear if the Justice Legion of Super Zoomorphs is one of these teams and simply adopted a unique name or is its own organization, similar to how the Legion of Super-Heroes and Legion of Substitute Heroes are similar teams, one inspired by the other, but operate separately unless a team-up is required.
