Is all might gay
Despite being separated Toshinori and David kept in touch via email throughout the years, as well as fantasize about their past together several times, Toshinori telling David about his weakening state and injury from his first fight with All for One. Eventually, Melissa invited Toshinori to the I-Island Expo to surprise her father and introduces Toshinori to David as 'someone you love'.
David still continued to create costumes for Toshinori after he left the United States, being the only one to do so. A young scientist, David is rescued by Toshinori, along with several fellow scientists, from an explosion in their building.
Those that are aware of David's existence very much so love the pairing, making it David's most popular ship, though it has some rivals in ToshInko and SirMight. David is shocked at the extent of the damage to Toshinori's body, and scans him to see his quirk levels.
This costume ended up being the iconic 'Young Age' costume for All Might. Horikoshi revealed that All Might has zero dating experience, and that just made him even more relatable and endearing to fthe anime fans. The two are often portrayed as having broken up when Toshinori needed to move back to California, leading to David getting married to someone else, but still having been in love with each other the whole time they were apart.
All that said, LGBTQ+ representation has been growing in other types of content, and while My Hero Academia is by no means the pinnacle of that, it’s always nice to see queer characters in such. Once he is defeated, David apologizes to Toshinori for causing so much trouble, admitting his fear of a world without the strong hero he knew Toshinori to be.
Toshinori encouraged Melissa to become a support engineer like her father, telling her that 'your father is my hero'. When David is captured by Wolfram, who turned out to be a real villain working with All for One to hurt David in order to get to Toshinori, Toshinori once again comes to his friend's rescue.
David and Toshinori first met not long after Toshinori moved to California from Japan. Toshinori eventually told David about his goal to become a Symbol of Peace for people to rely on.
Toshinori Yagi My Hero
Often times, this leads to them getting back together now that Toshinori is no longer a hero, and can have time for a real love life. During his final confrontation with All For One in the Final War, All Might dons a high-tech suit of armor, dubbed the Armored All Might, from his car.
David then shared this message with a crowd in L. Sometime after this, Toshinori had to return to Japan, a fact that hurt David, and is shown in Two Heroes to still bother and upset him. David and Toshinori are thrilled to see each other, and David quickly notices the steam coming off of Toshinori's muscled form, dismissing his daughter and assistant from the room to hide Toshinori's true form from being seen.
Does All Might is
DaveMight is a somewhat rare ship, due to David only featuring in the movie Two Heroes, which some circles of fans are unaware of. However, he lets go of the past, recognizing that Izuku and Melissa will protect the world as the next generation of heroes.
Others have Melissa becoming Toshinori's adopted daughter once he and David become a couple again. David makes note that Toshinori's outfit got tattered in the fray, and as a thanks, decided to study Toshinori to create a costume better suited for him.
A common headcanon among the fandom is that Toshinori and David were a couple or at least friends with benefits while they were young and living together in California. From their, the two grew very close in their college days, and became hero team in California.
David and Toshinori did their best to cheer up Melissa when it turned out she was born quirkless. Fearing his friend's untimely downfall and what the world will be like without the Symbol of Peace, David hired actors to pretend to be villains to steal back the Quirk Amplification Device he and his assistant created, hoping it can help Toshinori gain back the strength of his quirk.
All Might gaining shadowed eyes following his first battle with All For One possibly signified how he became a shell of his former self, marking the beginning of the end of his hero career.
