Chapter 110: Kids vs adults
Back at the fight against the Devil Brats, Team Peanut Gallery are getting overpowered from Toga disguised as Deku until Gentle gets an idea and ran off to get a shrink ray from the castle, causing Labrava to get distracted and gets severely injured much to most of her comrades' fury as they keep using super moves as the Devil Brats laugh. Gadget then told them that all they have to do is to let them have one for all and join their organization, causing the Peanut Gallery to start yelling at the brats for being so desperate to take over the world with one for all to the point of killing someone they hold dear to their hearts. Soon, Gentle came back and shrunk Toga back to her normal size before running to Labrava as the Peanut Gallery forced Toga to get rid of her disguise with their quirks. They then surround the Devil Brats and was about end the fight everything they got until Destro and Harima appears with the age controller machine. Destro then demand the kids to surrender, causing them to glare fiercely at him, which also caused him to blast the machine at them. However, the Peanut Gallery and their associates disperse, causing the age controller to zap the Devil Brats into sixteen-year-old teenagers much to their and their comrades' shock. Merlin then chews out Destro for forgetting to turn the knob to backward, which he does before activating it. However, just as it about to zap, Kacchan and Shoto destroy the machine, causing the laser to zap Creati back to four years old, which caused her to get annoyed before telling Destro that he and his comrades will pay for all they have done to them.
Destro and Harima then told the Devil Brats to leave everything to them as they, Team Reservoir Dogs, Nomu, Kurigori, Giran, Merlin, The Anti-hero Squad, and the Eliminator prepares to fight the kids. After Harima told the kids that good kids like them shouldn't be messing with dangerous villains like them, the fight began as Merlin transport everyone into a dimensional rift before Nomu and the Eliminator charged at them. However, Spiral and Energy blasted them before the younger kids use their super move against the adult villains, causing Merlin to change the Dimensional rift so The Anti-hero squad can attack the kids along with Team Reservoir Dogs. The kids then work together and fought for their lives, causing Merlin to get furious and start blasting the kids with magic, which also caused Creati and Makeover to create plastic weapons to deflect the magic until Eternatus and Ultra dog arrives to help avenge Deku. Soon, Ingenium 4told everyone to use a super move together, causing everyone to prepare to attack while Invisible Girl gets ready to reflect the move towards the villains and Labrava gives everyone her love. The villains but The Anti-hero squad, who got terrified and fly up to safety, rush toward the kids furiously vowing that they will ger revenge for All for one. The kids then combined their super move with Ultra dog and Eternatus, which caused an explosion that send everyone out of the battlefield. The kids then get up and ran back to the battlefield to see the Devil Brats, Kurigori, Giran, and the Eliminator standing over their dead comrades, including Destro and Harima while The Anti-hero Squad makes a run for it before anyone sees them. The Devil Brats then gives the kids a cold death glare as Tomura say that they are so cool, which did not affect the kids' determination to avenge Deku. Stain then warned the kids about their mental health because of their current obsession for revenge, causing Uravity, Froppy and Pinky to coldly tell them to shut up and fight them before saying damn it.
The devil Brats look at each other before nodding because they see there's no way to talk to the Peanut Gallery anymore. They then launched themselves to the Peanut Gallery to try to kill them, but the kids all dodged their attacks before counterattacking them with help from Eternatus and Ultra dog. The Eliminator and Giran then try using their strategy to kill the kids, but they were both blasted away by Kacchan's explosion. Pinky then try to melt the villains with her quirk but got blocked by Gadget's quirk proof bodysuit before he uses a sword and Octopack to fend off Creati, who creates a sword and shield to fight back. Soon, Gadget's had enough as he vowed that he and his comrades will steal one for all one way or another before whistling a signal, which caused Gigantomachia to appear as the kids become weaken from the fighting they did. The U.A. League and Lydia then see the kids in trouble before calling for backup.
