Immediately, the force of Dirge's aura burned into their brains and made them start going crazy. He also animated the buildings all around the team and had them reach out to grab them. Land Shark and Disco dodged the first swipe, but Torpedo was caged by a grabby tower. Land Shark attacked with a column of earth and found that Dirge was protected by a powerful force field. Torpedo crashed through the cage and dove so hard at Dirge that he was able to harm him even through the force field.
Because of the madness aura, Torpedo immediately asserted his Atlantean kingship and started assigning positions and ordering people around. Disco, likewise affected, became extra diva-ish and took everything Torpedo said as an insulting failure to recognize his fabulousness. I think Landshark was just curled up in a ball or fighting with the animated buildings or something. Then he freaked out and let loose with an earthquake, which trashed the neighborhood, but didn't otherwise help much. Torpedo did manage to save the bystanders by swimming so fast that he created an underwater twister to whisk them to safety.
Eventually Disco decided to show them how it's done. A combination of dice magic and determination points led to the emotion control lightshow of Disco's life, dazzling even un-targeted onlookers. Dirge cried out that "the Avatar" was coming and fled, also ranting about how the black sphere will rise and "he will come from beyond the stars and crush you all" as he fled into the volcano.
Shaking off their madness (well, as much as they ever do) and rallying the Atlantean troops, the Scrap Pile pursued the demon. While Atlantean mystics performed a collective binding ritual, Torpedo channeled the lava and Landshark reshaped the stone to support the Atlantean magic (also taking time to turn the carved face into a shark head). Disco capped it off with another light show, manifesting as a ghostly disco ball image shining briefly above the mountain.
Later they got a video call from Fire of Saturn and found out about the B Team's recent exploits. Also, Mister Chompers barked into the camera when Nimble showed up. Disco saw a subtitle appear underneath reading, "The sow is mine!"
