This manga is Kôhei Horikoshi's 3rd attempt at a successful series. The first was Oumagadoki Zoo from 2010 to 2011 and Barrage from May to September 2012. Before those, he also made 3 one-shots which built up the world of My Hero Academia.
Many of the cities and locations share the same or similar names of different planets from the Star Wars franchise, such as Musutafu (Mustafar), Kamino, Kiyashi Ward (Kashyyyk), Hosu City (Hoth), Tatooin Station, Jaku City, Nabu Island, and Gunga Mountain Villa. Takoba Municipal Beach Park, where Midoriya trains with All Might, is seemingly a reference to Dagobah, where Luke trains with Yoda.
Despite Midoriya and Bakugo being the inspiration for Class 1-A, Horikoshi has stated that neither of them are The Heart, and that role actually belongs to Kaminari and Kirishima.
Bakugo was originally supposed to have a friendly personality, but Horikoshi gave him a bastard-like personality instead because Horikoshi disliked his friendly version.
Izuku Midoriya's original character design had him with black hair (instead of his green) and red eyes (also instead of his green). This appearance is then given to his classmate, Fumikage Tokoyami.
