Charisma, Leadership of humanity and demonkind, Nigh-absoluteness against mortal opposition, Spatial manipulation, Causal awareness

Griffith is a very controversial character. He commits several heinous acts throughout the series, and whether he is an antagonist or deuteragonist afterwards is left very much to the reader's discretion, although series creator Kentaro Miura viewed him as the latter according to interviews. Following this, Griffith takes on a new persona, outwardly cold and logical, and completely untouchable to those who would harm his interests. Whether that is all he is now is left mysterious, as apart from a phantom heartbeat, Griffith's character is just as emotionally distant to the viewer as he is to those in universe.
