The Double King is a fat hunchbacked creature with two giant hands and feet and wears a grey-blue shirt with buttons and a maroon cape with a blue hem,showing only his eyeballs, covering his huge mouth with pointy teeth.
On his eyes, he wears 2 long crowns,he occasionally puts the stolen crowns on top of them.
While the Double King never spoke a word, it is shown that he is an egotistical, power-hungry tyrant on the hunt for any crown he sees, willing to kill for his goal.
He is unable to speak.
