Yes, Meruem, the antagonist character from the anime and manga series "Hunter x Hunter" is dead. Meruem was the King of the Chimera Ants and was known for his immense power. He met his end in a battle with chairman Netero, where he was poisoned by a deadly weapon called the Miniature Rose.
The Miniature Rose was a small but highly destructive nuclear bomb. In the anime, after a grueling battle with Netero, the chairman demonstrates his own resolve by triggering one within his own body, with Meruem caught in the blast. Despite initially surviving the blast, the King is fatally poisoned by the weapon's lingering toxicity, and he finally dies in a touching scene with Komugi, a human girl he had grown close to.
