Chapter 36: Lydia's true color
The next day, the kids find themselves becoming Izu's test subjects for a skin color changing experiment, which caused them to quickly get up and walk off in fear much to Izuku's disappointment as he starts pouting. Soon, Aunt Lydia enter the building and ask the Peanut Gallery how they are doing, causing Ochaco to get excited and hugs her aunt as Izuku solemnly said hello, causing Lydia to ask Ochaco what experiment Izu tries to do. After Ocahaco told her what Deku was doing. Lydia gathered everyone to tell them about taking them on a tour of her laboratory where she is working on an experiment, causing everyone to ask if it's not like Izuku's experiments, causing a montage of flashbacks with Izuku doing weird experiments in each one. After Lydia assures the kids that they are in good hands, she takes everyone onto buses to the old ship that soon sail off to a giant building where the laboratory takes place in.
When the ship docked, Lydia and the Peanut Gallery went inside to start the tour. First, they went to the potion room, where they see some workers test a few potions on monsters until one of them to give a potion a try. The younger kids all raised their hands up until Lydia looks at Izu and gets an idea. She then takes Izuku inside and told her employees that he stands still until the experiment is over. Soon, the continues with the second floor where the conference room is located. Afterwards, Lydia takes everyone onto the third floor where she takes everyone into a room with a giant vacuum cleaner inside. Ashley then asked Lydia what's the room is for, causing Lydia to tell the Peanut Gallery that this is where her master plan is going to be and they're going to be the first people to witness how the vacuum works. Lydia then revealed Izuku all tied up much to his friends, especially Ochaco's fury.
After a moment of Lydia's evil laughter, Shoto demanded an explanation, but just as Lydia was going to explain, Izuku quickly escape as he fends off the employees with his quirk. Soon he knocked an employee into a shelf, causing most of the potions to fell off and breaks. Suddenly a potion rolled toward Izu as he looks at it. Lydia then gets mad and told her employees to grab him causing Ochaco to tell Deku to look out, which also caused him to drink the potion and becomes a giant much to everyone's surprise. Izu then taunts the employees before taking off leaving a huge hole in the wall with the employees chasing him. Lydia then takes a deep breath before saying that she doesn't have to tell the kids that she's evil anyway, causing the kids to become more furious as Ochaco told her aunt that she won't get away with this. Lydia then laughs evilly before saying that she already has, causing Tensei to call Mrs. Uraraka and tell her what's happening. Mrs. Uraraka then tell Tensei to calm down before activating the tracking device so she can tell her comrades that they have a rescue mission to do, which caused everyone to say right to her.
