Tsuyu Asui, also known by her hero name Froppy, is a student at U.A. High. She has a frog quirk which gives her a long, prehensile tongue, the ability to jump great distances, stick to walls, and even camouflage herself. While she may not seem very expressive on the outside, Tsuyu is remarkably straightforward, calm, and observant. She is a loyal friend and a great team player, though she prefers only her closest friends to call her 'Tsu'. She often ends her sentences with a cute 'ribbit'.
