#bakugo prototype

Like Bakugo(Gogo) was supposed to have GREEN eyes and Izuku was supposed to have RED eyes. But not just that, their personalities were literally supposed to be the opposite too.

Originally, Deku would have been more introverted and more edgy, broody than he is right now, who didn't really smile much and was definitely not the optimistic, friendly and cute version that we know right now. Even his freaking personality was similar to how Bakugo is right now, even the way he puts his hands in his pockets

Meanwhile Bakugo was supposed to be the friendly, outgoing one who is too innocent for his own good, talks without thinking and doesn't realize he's accidentally hurting the people around him cause he's too socially clueless to pick up on other's emotions and social cues, while also having a secret "sadistic" side that comes out during battle.

So if we think about it, it's not that their original prototypes switched, it's that they literally merged.

Bakugo is still pretty bad at social cues and he is honest to the point of being an ass to others, except it's not cause he's cluelessly innocent, he just somehow ended up with Deku prototype's original design...aka grumpy looking boy who barely ever smiles and also hates social interaction. Plus the red eyes.

And Deku is the one that looks like a ball of sunshine now, who's innocently optimistic and overly friendly, but still having that edge of badassery that his prototype did. And he got Gogo's green eyes now.

On top of that, Bakugo's prototype was supposed to have the nickname Yamikumo for Deku that symbolized his personality(because he's always so reckless), just like how Deku now calls Bakugo Kacchan, which is also symbolic to his personality (many people have pointed out that it can also be translated to Victory-chan).

So, basically, Hori had this idea first to have all these characters and make Uraraka Deku's love interest and have Bakugo have his own character development arc. And then he decided to change things up and throw away the Uraraka being the love interest thing, and make Izuku and Bakugo's storyline tied together instead. And the fact that their current characters are literally a mix of their original prototypes just proves how much Horikoshi meant their characters being tied together.
