Tales From the Kryptomites Part 2 is the fourth webisode of Season 3 of the DC Super Hero Girls webseries.
This episode's title is a reference to the comic series Tales from the Crypt.
One rainy night at her lab. Lena Luthor's pulls out a feisty red Kryptomite from a creation oven with blacksmith pliers. She drops it onto a lab desk before readying a laser. Meanwhile, at Super Hero High, the Save The Day Alarm goes off.
A collection of students race out the front doors of the school to respond to it. They arrive in Metropolis, where several green Kryptomites are making trouble in the city and attacking the citizens. Supergirl begins to weaken again due to the effects of the Kryptomites and falls out of the sky but is saved by Wonder Woman from falling to the ground. She tells Batgirl to take the lead while she takes Supergirl away from the Kryptomites. Batgirl then races into battle, and shatters several Kryptomites, as does the Flash, Cyborg, Bumblebee and Harley Quinn. As they celebrate their initial success, it then begins to rain, which causes the shattered Kryptomite fragments to multiply into several more. Bumblebee ponders how they will stop them if they can multiply into more if they smash them. Frost then walks back into a kryptonite fragment and attempts to freeze it, before Poison Ivy notices that it has not turned into a Kryptomite as it is covered from the rain by an awning. Frost and Ivy examine the crystal and notice that it is also organic, meaning they need by chemistry and biology to defeat it, before racing off to the science lab at the school. While Bumblebee, Cyborg and Harley are surrounded by Kryptomites, the Flash speeds by and shatters them all before joining Batgirl in the Capes and Cowls Café and finding it swarming with Kryptomites attacking the customesrs.
Steve Trevor attempts to keep them at bay with a mop, just as Flash arrives behind the counter and uses a trash bin to trap inside all the Kryptomites in the Café. Just as Steve thanks Flash, a red Kryptomite approaching him from behind makes him incredibly angry. The Kryptomite jumps on the counter, and Batgirl notices how the different colours of the Kryptomites effect people in different ways. As the Flash catches it in the trash bin, he guesses that red ones create anger. Outside, Frost and Ivy return to the scene, with a new formula that inhibits their crystallization and stops the Kryptomites. The two then hand guns and balloons full of the formula to their classmates and use it to defeat the Kryptomites, shrivelling them into harmless, inanimate stones.
Batgirl then opens a large container as Cyborg drops a large load of the former Kryptonites inside and indicates that that is the last of them. Batgirl closes the container as the citizens and other heroes cheer. Meanwhile, Harley holds a shrivelled red stone, intending to keep it for herself as it matches her dorm decor. The stone, however appears to still be a living kryptomite.
