I vote Francisco de Goya's "Saturno Devorando a Su Hijo," a dramatic canvassed mural depicting the Roman god Saturn, so afraid of his own godly children usurping his rule over Rome's heavenly kingdom, that he resorts to devouring his own sons to protect himself.
Goya painted it on one of his own walls, before it was transferred to canvas after his death. You'll note the cannibalistic intensity from the select white only from the victim's body and Saturn's own knuckles as he clenches his victim mid-feast.
I think it would most clearly say: "I am SNR. My tenuous grasp on my own kingdom will revert me to whatever means I need to retain control. And sometimes, the effort needed to retain control over my kingdom and/or life will transform me into someone, or some
thing else entirely. But it matters not."
