Unless you happen to be a real pop culture guru, you might not notice that the creators of My Hero Academia littered the series with references to a plethora of Japanese and American franchises. If you're an MHA fan who also loves Star Wars, prepare to get a kick out of the series's locale names and the visage of the main baddie.
Marvel fans might take note of the plentiful Marvel references in My Hero Academia, including a scene from Iron Man 2. The series even nods to anime like Fullmetal Alchemist, Naruto, and Dragon Ball Z. Plenty of Western cartoons reference anime in clever ways, so it stands to reason many anime and manga series will return the favor.
These My Hero Academia Easter eggs feel all the more awesome when you learn Kohei Horikoshi, the manga creator behind the series, has a deep love for Western superheroes, anime, and other pop culture that influenced his work. He throws this stuff in for more than just the hell of it - he includes it because it's his passion.
These cultural references in My Hero Academia only make the viewing and, in the manga's case, reading experience a lot more fun.
