Depiction in the web series
In Gone to the Dogs Part 1, Ace and Krypto investigate the missing jewlery at Eclipso Jewels independently from their respective owners, Batgirl and Supergirl. Krypto finds Roz in security footage wearing an emerald necklace inside the store and they decide to pursue him. In Gone to the Dogs Part 2, Catwoman is revealed to be Roz's owner, secretly keeping him against Super Hero High pet policy, saying "[he] has nowhere else to go". The dogs find Roz who buries the emerald necklace along with most of the jewelry and proceed to chase him up a tree. Roz escapes to a rooftop but is finally chased off by Krypto and captured in a net by Ace. Catwoman then arrives and snags Roz from them, while Roz tauntingly waves goodbye to Ace and Krypto. Later that night, Roz steals Krypto's dog tag and brings it to Catwoman.
In All Pets Are Off, as Supergirl mentions that Krypto is missing on the day of the Super Hero High pet show, Beast Boy reports that Roz has also gone missing. During the pet show, the rest of the pets are stolen in the Battywagon by Artemiz who plans to bring them to Apokalips to become war beasts in Granny Goodness's animal army. Roz is seen among the stolen pets in the back of the Battywagon by Supergirl's x-ray vision. After Supergirl destabilizes the Battywagon by freezing the road, the pets break free and Roz attacks Artemiz as she drives. After Artemiz is defeated, Roz runs out with the other pets and is confirmed rescued by Wonder Woman.
