What was she thinking? Midoriya could only imagine. He himself used to imagine countless uses of the quirks all the heroes had. Heck, he had at least ten notes that had notes about pro heroes he saw, and researched. 'Hero analysis notes for the future'. He never knew they'd come real. Before Midoriya broke into another flashback, he shook his head and focused back on Nensu. What could they possibly make? A destructive power Midoriya could not yet control, and Nensu's fire and ice(which were very well under control) could not get along well, not yet. It would help them clear out big areas, but Midoriya didn't like breaking fingers a lot.
