Incase you didn't know, yamikumo midoriya and gogo katsuki are the prototypes or drafts of izuku midoriya and katsuki bakugou. So to say, they're the original versions but the author changed them since he wanted the story to be for all ages. Bakugou was originally named "gogo katsuki" and was supposed to be lustful towards yamikumo, to also be more cheerful and nicer towards people but gets easily jealous and possessive when someone makes lust movements towards yamikumo other than him and gets quite frightening, how he was also somewhat a yandere from what I've heard. Izuku was also originally named "yamikumo midoriya" and was supposed to be an emo and he was still quirkless but was very smart and good with building, technology and design(kinda like hatsume) which is why he made it to ua. Oh and also, this might contain some inappropriate stuff. Just warning you all
