Gandhari

Gandhari was the powerful queen of Hastinapura.

History
When Gandhari married the sightless king, Dhritrashtra, she chose to wear a blindfold in order to share his blindness. Only once did she let her blindfold drop: to see Duryodhana, her eldest son. Had he been naked at the time, her gaze would’ve made him invincible. But the dude was modest and left his underwear on, thereby remaining vulnerable.

Trivia

 * The tale of Gandhari meeting her son is similar to the story of Achilles.
