Yeah, Ganondorf is part demon in most of his appearances, and is clearly not a typical 'mortal' human in any game. I think Zant actually kills himself though,

Yeah, Ganondorf is part demon in most of his appearances, and is clearly not a typical 'mortal' human in any game. I think Zant actually kills himself though, as the last act of spite against Ganon for something or another. For other examples: Both Astor (Age of Calamity) and Chancellor Cole (Spirit Tracks) get taken over by their demon king rulers before their final battle (Ganon and Malladus respectively). Vaati becomes his one winged angel form in all games where he's a major villain or final boss. Master Kohga gets killed by his own idiocy at the end of his boss battle. And Yuga takes over Ganon, before getting killed in that sort of merged form instead. At that rate, the only 'human' who doesn't do this is Lady Maud from Tri Force Heroes, and she's neither particularly threatening nor actually dies after the battle.
