I'm pretty sure that Ujiko is the same doctor from episode one. They look alike at least. I hadn't thought of how he could have given away his patient list to All For One, but that does sound quite possible, especially when they are willing to experiment on dead students too.EDIT: Wait, is Ujiko the pediatrician that told Midoriya he had no Quirk? That would track with how he knows so much about Quirks. Even more dark if he leaks his patient list to All for One so he hand picked what Quirks he wanted over the years.
Yeah, his original name was Maruta Shiga. The term maruta was referring to human victims that were experimented on in Japan's Unit 731 complex during WWII. That would have included plenty of Chinese families and there was a good amount of backlash towards that decision. They did change his name for the volume release, but as far as I know, the manga is still banned in China.Is this doctor character the one that got the creator in hot water with the Chinese a few years ago?
