Final answer:
In 'My Hero Academia,' besides Sir Nighteye and the prophesied yet unrealized death of All Might, other characters who have died include Magne (Kenji Hikiishi), Twice (Jin Bubaigawara), and Snatch (Sajin Higawara). Future episodes or chapters may introduce additional deaths as the story progresses.
Step-by-step explanation:
You have asked about characters who die in the anime My Hero Academia (MHA). It's important to note that discussing such details can be considered a spoiler for those who haven't caught up with the anime or manga.
As of my knowledge cutoff in early 2023, apart from Sir Nighteye and the future death of All Might that is hinted at but has not occurred in the series, other characters who have died include:
- Magne (Kenji Hikiishi) - dies during a confrontation with the League of Villains and the yakuza.
- Twice (Jin Bubaigawara) - dies during the Paranormal Liberation War.
- Snatch (Sajin Higawara) - killed during a confrontation with the League of Villains following a heist.
The series continues to evolve, and it's always possible that future episodes or chapters may reveal more character deaths.
