I have an BNHA au version of one of my characters MechaBetty. She has the quirk of recycle/machinery, where she can absorb scrap metal and such and make them into machines that she can power if they are connected to her, but only ones she knows really well. After years of studying hero items she has memorized her basic "suit" which she can make at will (given basic materials), and allowed her to barely pass the entrance exam for a hero course.
thats pretty cool! i can imagine her in the entrance exam collecting scraps from other kids fighting the robots and building something pretty powerful
my kid is kinda like, a support hero? he’s probably in the department of support/general studies or smt. i guess he could make himself unknown to others for a short duration in the exam, but i dont think he’d manage to pass.
