Chapter 203: Prom takeover
Soon, everyone went to Harmony Island to get suits, ties, and dresses for prom, causing the council to sacrifice the donations to build a new boarding school in Japan as the Peanut Gallery admired each other's prom outfit until Hisashi and Gretel appears dressed up as a prince and princess respectively, which also caused their comrades to complement their outfits before getting Cadet 1a, so they can go back to Braveworks Academy. On their way back, Izuku apologized to the twins that they didn't get to see the homes of Drake, Sam, Patricia, Celia, Plunderin, and Thomas, causing the twins themselves to say that it's alright because they can go see them after graduation. Two weeks later, the Peanut Gallery went to the same hotel that the Peanut Gallery (except for the twins) went on vacation in Paradise Resort, because it is where prom will be taken place.
Soon, after twenty minutes of talking and waiting, everyone heads inside and went to the ballroom as music started playing along the montage. The montage then ends with the twins taking Drake and Gretel to the dance floor to dance together, causing their parents to put their hands on their hearts and goes "aww" as Queen Gwen, and King Henry smiled at each other. While this is happening, two sinister looking silhouettes watched the Peanut Gallery enjoying prom before deciding to do something. After two minutes, the lights turn off as sounds of fighting began until the lights turn back on to show that everyone but the Peanut Gallery, hero council, Gwen, and Henry all tied up as two familiar villains laugh evilly before jumping off a windowsill, causing everyone to get defensive and they realized that it's Black Might and Red X, which also caused Red X to sadistically ask the Midoriya twins if they missed them.
While the hero council got their wives and husbands untied, Gwen and Henry quickly confronted the Evil twins and ask them what they are doing out of Dungeon Fortress, which caused the evil twins themselves to smile evilly as they decided to take turns to tell them how they got out of Dungeon Fortress. A flashback then begins as the Evil twins revealed that while they were in Dungeon Fortress, Red X created a plan to break out. After replacing themselves with life-like dummies, they lay low and befriended overpowered villains until they saw the Peanut Gallery getting stuff for prom, which caused the Evil twins to get the same idea and told their new team of villains their plan to kill the Peanut Gallery and their parents before destroying peace and harmony their own way. the flashback then ends with the Evil twins telling their comrades to get into positions and wait for them to give them the signal. Just as the Peanut Gallery was about to attack, Black Might made bird calls to get the overpowered villains that he and Red X befriended inside the ballroom to start attacking, causing the Peanut Gallery to get blown away by a villain, who then told his comrades that Red X and Black Might wants them to take the hostages all the way to the top of the hotel.
