Superman Day 2026: Supergirl's Zoo-per Heroes Krypto's Big Break Special Edition

Plot

SUPERGIRL. KRYPTO. AND ONE VERY SUPER ZOO.

Krypto just wanted to pass the time while Supergirl handled Watchtower business... but who could resist the temptation of the Justice League’s super-sweaty socks? One accidental button-press later, and Earth’s mightiest heroes’ costumes are blasted into space — only to land in the hands of a group of zoo animals who suddenly gain super-powers!

Now it’s up to Supergirl and Krypto to wrangle:

the fastest sloth alive

a wonder seal

a bat-rhino hybrid

and an unexpectedly super-powered lion

... all while dodging an over-eager zookeeper who’s determined to catch Krypto.
