Toph Beifong

Stubborn, uninhibited, and exuberantly self-confident, Toph loves to say and do whatever she pleases. She hates formalities, rituals, and fancy stuff (like shoes). She’d rather feel the pebbles and dirt under her bare feet. Toph has no patience with other people telling her what to do, but she’s more than happy to boss others around. Used to being underestimated, she uses people’s misperceptions of her to gain an advantage over them. A human lie detector, she can sense the slightest changes in people’s heartbeats and breathing. Toph often hides her feelings with humor and bravado, but with the right person, she’ll open up and show her vulnerable side.
