Chapter 117: Giant Mystery and Deku vs Robogigantomachia
Gadget ask the heroes if they're ready to end the war once and for all, causing the heroes to say ready as Mystery attacks with Mega horn missile to start the fight. Robogigantomachia then fall back before launching himself toward Mystery to punch her but got blocked by Mystery herself as she uses her muscles to push the robot away from her. Deku then tell his comrades to get inside the robot as he tries to blast Robogigantomachia with one for all with no avail. Ryuku then gets an idea and told everyone to support Mystery and Deku while she and Midnight makes an opening. Soon, everyone gets away from Mystery's giant feet as she and Robogigantomachia clashed with each other until Himiko activates missiles, which caused Mystery to counterattack with mega thunder horns. Earphone Jack then attack Robogigantomachia with heartbeat surround while the other Peanut Gallery members attacks with their quirks as Labrava gives them love to make them stronger. While this is happening, Ryuko and Midnight made a hole on the right leg of Gigantomachia, causing Robogigantomachia to quickly swat everyone but Mystery and Deku away before preparing to crush the heroines. Midnight then quickly pushed Ryuko off and sacrifice herself to get crushed by Robogigantomachia's hand as the villains laughs evilly from the inside. The Peanut Gallery and their associates then became furious as Mystery punched Robogigantomachia and made him go flying with her horns and uppercut punch before neighing angrily. Deku then then activates support bond before telling everyone to get inside but be careful, causing his comrades to set off inside to defeat the Warcraft of doom.
Once inside, the heroes immediately look at a map while Mystery continues fighting Robogigantomachia with Deku activating support bond, which caused earthquakes inside. Soon, the heroes move forward before encountering a wave of goons. Meanwhile back outside, Mystery uses MMA skills to continue fighting before using a new super move called mega buddy charge, which knocked Robogigantomachia into a building and creates a domino effect. Mystery then takes a breather before asking Deku what's everyone going to do inside the robot, causing Deku to tell her that they're going to give them an advantage by forcing the villains out of Robogigantomachia, causing her to understand before continue fighting Robobogigantomachia as she snorts and moo angrily. Meanwhile, everyone else try to fight the first wave of goons while the inside shakes because of the fight still going on outside. Soon, everyone saves each other from three impacts as Mystery smacked Robogigantomachia down on the ground. Mystery then use high horse kick to send Robogigantomachia flying, causing Froppy to get mad and said that this is the second time that they were almost killed while being inside a moving robot, which also caused her dad to tell her that the fight isn't over yet as they and their comrades moves on from the fallen goons before encountering a second wave. Meanwhile, Mystery bit Robogigantomachia's arm while Deku flew to the hole and shot one for all to blast whatever inside, which caused an explosion that made the leg unable to move as Deku laugh mischievously before flying back to Mystery's head. Mystery then starts to lift Robogigantomachia up, causing everyone inside to fall to the ceiling before protecting themselves from impact again as Mystery threw Robogigantomachia with sheer force. Deku then smile as he patted Mystery's forehead saying good girl to her, which caused Mystery to blush and claps her lips together. Mystery then watched Robogigantomachia gets up before telling Deku to give her more power, which Deku say ok to before activating super support bond+, which caused Mystery to grow until she's able to pick up Robogigantomachia much to the villains' shock as she rips the head off and make an easy passageway for her comrades to face the villains before putting the head back on.
After Deku made Mystery shrank back to the giant size she was, the Devil Brats activates autopilot to deal with the Peanut Gallery and U.A. League who's inside the robot. The they then confront the heroes on their way to them before saying that they are so going to get it before fighting them. However, the fight only takes three minutes as the heroes chased the villains out of the robot as Robogigantomachia is still on autopilot much to Deku's confusion as Mystery fights on. Soon, the Devil Brats surround Deku, causing him to try to tell them to change their ways so they won't go to Tartarus. He then gives the villains a heartfelt speech about their similarities to make the world a better place, and how they all can make a difference in the world despite being called freaks, which caused the villains to initially smile gratefully and call Deku a true hero before smiling deviously and said that they must keep All for one's legacy going and steal one for all to take over the world. Deku then gives the villains a deadpan look as he said that there's no point in talking to them anymore before activating super support bond+ to make Mystery grow so she'll gives the villains an armor piercing death glaring before neighing so loud, that not only it blows the villains into police cars, but also made windows shattered. Mystery then crushed Robogigantomachia before Deku get off her to give her a shrinking antidote to get back to her normal size. Soon, Mystery's family and friends all cheers for her and Deku until Special remind everyone that people died during the war, causing everyone to stop and become sad before saying right.
