When scandalous lies about the girls show up on the Internet (where "it must be true if it's on the Internet"), they track it down to Silico, the villain from "Viral Spiral."
Tropes:
- Actually a Doombot: After they defeat Silico, he turns out to be a hologram. Buttercup Hangs A Lampshade on it, calling it another superhero cliché.
- Backstory: Silico explains his vendetta against the girls. As a kid, he had no friends so he created an army of AI friends. They were destroyed when a monster the girls were fighting was knocked over his home.
- Berserk Button: Being called "Disorganized" to Blossom. Silico makes the mistake of calling her such in his posts which gets Blossom angry enough to wreck his whole hideout with wall pin shaped light constructs.
- Disproportionate Retribution:
- Silico's grudge against the girls is due them accidentally knocking a monster into his workshop in the past, which crushed all his robot friends he created.
- Buttercup punches Bubbles in the arm for "hitting her" when they tried to charge Silico's giant robot despite it clearly being accidental and that Silico was using a hologram to cause them to charge into each other.
- Malicious Slander: Silico's plan this time involves posting slander of the Powerpuffs on the internet. Since the people of Townsvilles believe anything on the net, they quickly turn against the girls.
- Not Me This Time: The girls break into Mojo Jojo's hideout and beat him up for one of Silico's fabricated stories—that Mojo is cooking kittens when in fact he was making dinner for kittens. Though when they return to apologize, he reveals he was likewise planning to use them as an army fitted with lasers (which fails as the kittens are too distracted to obey his commands).
- Shout-Out: The title is a reference to the AMC series Halt And Catch Fire.
- Torches and Pitchforks: The Townsville people, having bought into the Internet lies about the girls, chase them with images of torches and pitchforks on their phones and tablets.
