Izuku Midoriya's father is a man named Hisashi Midoriya. He is a businessman who works overseas and has an unnamed fire breathing Quirk [4] [5]. Hisashi is only mentioned once in the series, during the first chapter/episode, when his wife Inko Midoriya mentions his fire-breathing Quirk to Doctor Daruma Ujiko when Izuku was a baby [8]. There is little information provided about Izuku's father in the manga, but it is assumed that Hisashi's fire-breathing Quirk is a result of his genetic makeup [7]. No further details about Hisashi's current activities or status are known [1] [5].
