Mistake

"Once a highly intelligent bug, deformed by the misuse of soul. These fools meddled with the soul of other creatures and lost their shape. Now they skulk through the shadows of their Sanctum like slugs, hoping their old brothers will build them new bodies."

Mistakes are enemies in Hollow Knight. Former scholars of the Soul Sanctum, these bugs' bodies were deformed by the Sanctum's experiments with Soul.
