They flew to Mexico, where Coulson and some of his team were preparing to investigate the appearance of a child soldier of an AI super-intelligence, MACH-25, that hijacked a transport plane. Coulson and the team were attacked by a super-grunt named Mace, who infiltrated their camp and disabled F-302. The whole team was then sent into space, where they were pursued by an AI subspace conduit called Serpent, which Bugger attacked and killed. Back on Earth, Mace was battling with Coulson's team, and was telekinetically snapped inside a giant robot to kill her. Though Mack defeated the robot, he then retreated after thinking Coulson was dead. Knowing that his death would kill the group, Coulson sacrificed himself to destroy the robot, leaving his team to be captured by the AI and asked for a meeting with Fury.
He then left, commenting to the girl that, although he might not be able to cure her, he would never leave her alone. Amos left with his team and searched in the desert for the girl, not realizing that the creature they encountered had been the real sprite. They ran into Stinger and were all taken captive by it and the hero Skeets. They were rescued by Punisher, who fought and defeated Skeets. They had to withstand several attempts by the creatures to stop them from leaving, but Stinger promised to return soon and took his team back to the desert. They encountered a woman who had escaped Skeets and weaponized the creatures with the intention to use them against the city, in hopes of being elected Governor.
Returning to the Amazing World of Gumball, the protagonists eventually learn the purpose of the mission that was assigned to them. Meanwhile, in Petiology, Max's dad, Fred, told Max that he would reveal the secret of the germs the virus contained if Max could prove to him that he was the most handsome. After completing the task, Max found out that he had been using Fonzarìa's wig, which allowed him to become the most handsome. Max then asked his dad for the antidote, but Fred said this would not be possible as he was a "real" superhero, and that he would be forced to infect himself using the vaccine. d2c66b5586
