Mitsuki Bakugo

Mitsuki is a woman with spiky ash-blonde hair and red eyes; the same aforementioned traits that her son Katsuki inherited. Because of her Quirk, she maintains a youthful appearance despite being in her late thirties. At home, she is seen wearing a white blouse underneath a lavender cardigan with a short black skirt.

Much like her son, Mitsuki has a short-tempered nature that quickly leads to an aggressive attitude, heavily suggesting that Katsuki got his unpleasant traits from his mother. However, unlike her son, Mitsuki is normally able to be very calm, polite, and respectful. Mitsuki gets along well with her husband and was very respectful towards the U.A. teachers, despite her son's kidnapping.

Mitsuki recognizes the flaws in her son that were instilled in him due to a combination of his innate talent for seemingly all he does, his powerful Quirk, and the way people would constantly fawn over him during his childhood because of these attributes. Mitsuki disapproves of Katsuki's arrogant and self-centered attitude and even smacked him several times during home visits from U.A. teachers. Despite recognizing all of Katsuki's flaws, Mitsuki desires that he become a Pro Hero and is thankful for the U.A. teachers for believing in his potential. She is also glad to see that his teachers see Katsuki for his tenacity rather than his aggression.

Mitsuki’s Quirk allows her to produce a smooth liquid from their skin.

Its moisturizing effect gives Mitsuki a flawless skin quality which maintains her youthful appearance, despite her age.

When genetically combined with her husband's Quirk, it results in an Explosion Quirk, which is used by their son.
