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.

After the Brain-Globes are defeated, the team members go their separate ways but the comic book narration promised the Legion of Super-Pets would soon join forces again.

Traditional versions of Beppo and Comet appeared in issue #6 of Krypto the Superdog, an outside continuity comic series aimed at younger readers.

When they fail, they summon his friends Cosmic Boy, Lightning Lad, and Saturn Girl, the founders of the 30th century team of teenage champions called the Legion of Super-Heroes.

Knowing Superman's future, they recruit Streaky the Supercat, Beppo the Super-Monkey, and Comet the Super-Horse (who they knew would be a companion to Supergirl after she arrived on Earth years later).

After passing four challenges to show he can perform impressive feats even though his main power is shape-shifting, Proty II is officially welcomed into the LSP.

This roster includes Krypto, Titus (Damian Wayne's pet dog), Streaky, and the Bat-Cow (a cow with a bat-shaped patch over its eyes, previously introduced in Batman Inc.), along with two new animals making their first appearance in the story: Flexi the Plastic Bird (a parrot with Plastic Man's powers) and Clay Critter (a creature resembling Proty, possibly related to Clayface).

Other members include Ch'p and B'dg (H'lvenites from the Green Lantern Corps), the Terrific Whatzit (a turtle with the Flash's powers) Jumpa the Kanga (an Amazonian breed of kangaroo which was probably bred and originated in Themyscira, owned by Wonder Woman), Ace the Bat-Hound (Batman's dog originally owned by an engraver named John Wilker), Fuzzy the Krypto Mouse (a mouse that was given super-powers – similar to Superman – by an unusual form of kryptonite), PB (a potbellied pig who can change size in scale, and another of Wonder Woman's pets), Mark, and Keith (a pair of guinea pigs; Mark is the brown one who possesses pyrokinesis, and is Cyborg's pet, while Keith is the white one who possesses cryokinesis (later hydrokinesis after Lulu (a hairless guinea pig who possesses flight and telekinesis, and is Mercy Graves' pet) smashes him against Mark), and is Aquaman's pet (actually all four characters from the CGI-animated film DC League of Super-Pets)).

The group is revealed to have secretly operated on several missions over the years (indicating that parts of their Silver Age history may be canon once more), but disbanded after a battle with Dex-Starr and Harley Quinn's hyenas Bud and Lou resulted in Clay Critter's apparent demise.

The current line-up is given as Ace, Damian Wayne's friend Bat-Cow, the Wonder Twins' pet Gleek, the squirrel-like Green Lantern B'dg, Jumpa the Kanga, Krypto the Superdog, and Streaky the Super-Cat.

Comically, while the othe super pets conerse with one another about complex plans, Bite-wing behaves like an ordinary, oblivious, affable, good-natured dog.

Now we were recognized as full partners and designated familiars, an ancient referral to the bestial accomplice of the witch... Then came the great rebirth of mighty Solaris, and his patronage.
