The later one-shot issue "DC 1 Million 80-Page Giant" #1 introduced a coalition of different super-powered animal teams collectively known as the Legion of Super-Familiars, carrying on the legacy of the Legion of Super-Pets. Each planet of Earth's solar system in the 853rd century has its own local Legion of Super-Familiars team, all of which are organized and governed by the Legion of Executive Familiars, which includes Krypto-9 (descendant of Superman's dog Krypto), Octus the cephalopod from the Eighth Dimension, the worm teleporter Wormhole, and the twin sun-dogs Phaethon and Savitar. It is not made clear if the previously seen Justice Legion of Super-Zoomorphs is just one of the many Super-Familiars teams using a different name, an earlier version of the team, or a special team connected to the larger Legion of Super-Familiars, similar to how the Justice League occasionally co-exists with splinter groups such as the Justice League Task Force or how the Legion of Substitute Heroes is inspired by the Legion of Super-Heroes but operates independently unless a team-up is required.
