Dimitri Alexandre Blaiddyd

Dimitri Alexandre Blaiddyd (Japanese: ディミトリ＝アレクサンドル＝ブレーダッド, Hepburn: Dimitori Arekusandoru Burēdaddo) is one of the main characters in Fire Emblem: Three Houses (2019) and its spin-off Fire Emblem Warriors: Three Hopes (2022), both of which are part of Nintendo's tactical role-playing video game franchise Fire Emblem. He is the leader of the Blue Lions House at Garreg Mach Monastery and the prince of the Holy Kingdom of Faerghus, alongside Edelgard von Hresvelg of the Black Eagles and Claude von Riegan of the Golden Deer. His house is one of the houses the protagonist, Byleth, can serve as a professor to, and is accompanied by multiple other students, including Dedue Molinaro and Felix Hugo Fraldarius.

Dimitri appears to be an honorable, idealistic, and kind man who values the ideals of nobility, but beneath his noble persona lies a violent and ruthless nature, as well as trauma caused by an event that has haunted him since childhood. Since then, he's been hunting down the people who he believes were responsible for the event that has plagued him for years. Following the five-year time skip, during the War of Fódlan, Dimitri's sanity has been severely reduced to that of a vengeful and sadistic individual who has little regard for anyone's life, including his own. If the player supports him, he will become the main protagonist of his route, and as the story goes on, his sanity will be restored. However, if the player opposes him and joins Edelgard, he will become one of the main antagonists of the Empire routes in the games.

He has received a positive reception from fans and critics alike, with many praising the vocal performances by Hackney and Ishikawa respectively, and his character development in the Azure Moon and Azure Gleam routes in Three Houses and Three Hopes respectively, as well as for his kindness, strength, and vulnerability that he displays and the handling of his mental trauma and sanity.
