Chapter 116: Robogigantomachia unleashed
The Warcraft of Doom was finishing building their giant robot when Deku breaks down the door and led his comrades through the agency, they then reached Gadget's laboratory and confronts them, which caused the villains to make sure that Deku is no ghost before asking him how he survived the machine's laser. Deku then gives the villains a deadpan look before telling them to surrender and disband the organization, causing the villains to glare at him. Deku then chew the Devil Brats and their comrades for making his team think that he's dead and toy with their emotions afterward before giving them an ultimatum, which is either face the consequences of their villainous acts or join Gigantomachia on the moon. The Devil Brats then contact a goon to ask if Gigantomachia is really on the moon before giving the Peanut Gallery and the U.A. League cold death glares because the goon confirms it. Special then told everyone to prepare for a fight, which caused the villains to laugh and say that they aren't fighting them, they are fighting Robogigantomachia. The heroes then became confused, which caused the villains to laugh evilly more.
The ground then shakes after Spinner pressed a button nearby, causing the heroes to look around cautiously until they realized that they're rising and jump down to see Robogigantomachia. The Devil Brats then explain that Robogigantomachia is a robotic clone of Gigantomachia himself before deciding to tell the heroes about their robot. They then told the heroes about the Robogigantomachia's immunity, power, strength, and agility before teleporting themselves into the robot along with their comrades. Deku and Uravity then try to rush in and fight but Itsuka grabs them, causing Uravity to tell everyone that they need to stop them before they activate Robogigantomachia. Deku then remind Uravity that they have Mystery and him as their secret weapons. Soon, the villains activate Robogigantomachia, causing the heroes to get out of the way as the Devil Brats laugh mockingly. They then told the heroes that they always have a backup plan and Robogigantomachia is the secret weapon that's going to destroy everything in Japan, causing Deku to taunt the villains by laughing mockingly before telling them that he too always has a backup plan that's going to take them down.
Deku then whistle, causing Mystery, who was drinking water from a water silo, to get on all four before neighing as she runs to the Warcraft of Doom as she makes earthquakes along the way. Soon, Mystery reached the agency, causing Deku to fly onto her head before sticking his tongue out while giving the villains the middle finger. He then humorously introduced Robogigantomachia to his beloved horse that's going to kick his butt, causing the villains, especially Gadget to give him a deadpan look before saying that the fight begins now, Nejire Chan then say wait before flying up to Deku and ask what she and the others going to do, causing Deku to tell her that he and Mystery will distract the robot while someone make an opening to the inside. Everyone then says right afterwards.
