A fourteen-year-old prodigy who was raised as a weapon
The most complete betrayal in the history of the medium
Editorial estimates on a 0–100 scale, calibrated against every other character in the index. Not official canon.
Griffith is a charismatic mercenary commander with a dream of his own kingdom, and for a long stretch of the story he is genuinely admirable. What he does to reclaim that dream after losing everything is the single most notorious sequence in manga, and it recontextualizes every kind word he ever spoke. He is proof that a villain's earlier decency can be the worst part.
He is a demon prince at the head of a real army with a nation's genuine devotion behind him.
The one person he could not fully own is still alive and still looking for him.
The most notorious betrayal in the medium, and the reason a generation of readers still discuss the moment in code rather than by name.
The charisma is the plot. An entire army follows him to their deaths because he is genuinely inspiring, right up to the moment he uses it.
What makes it a tragedy is not what he becomes but how genuinely good the earlier version was, and how deliberately he gave it up.
He sacrificed an army of people who loved him and then returned as a head of state with genuine popular support. The damage is both physical and moral.
