Frog

Frog is the Quirk of Tsuyu Asui.

Description
Frog is the summation of Tsuyu's many frog-related abilities.

This includes great leaping (and thus kicking) ability, wall clinging, a powerful extending tongue, camouflaging and fast swimming. Tsuyu appears to have access to all abilities used by frogs, regardless of breed.

Tsuyu's stomach is capable of inflating, which allows her to secrete an irritating toxin contained in the walls of her stomach. Tsuyu can further use her stomach to store items that she swallows, regurgitating them out if necessary.

As frogs are cold-blooded creatures, Tsuyu is sensitive to the cold, with prolonged exposure preventing her Quirk from being used while additionally making her feel drowsy and lethargic.

Usage
With Frog, Tsuyu excels in aquatic environments, freely moving through water without losing strength or agility. She's capable of fighting or rescuing victims underwater with no problem, making her very useful for missions taking place in those situations.

However, she is shown to be more than agile and acrobatic on land as well, as she can leap very high and cling to walls. While Tsuyu can walk like a normal person just fine, she has never been shown running, instead hopping on all fours like a typical frog. When stuck to a wall, she moves around by crawling.

Tsuyu makes great use of her tongue to reach faraway objects or rescue those in danger, as it can extend quickly and very far. Her tongue is strong enough to carry a person as well as launch them a fair distance. Tsuyu can also swing it fast enough to use as a whip.

Named Super Moves

 * Camouflage: Tsuyu can change the coloring of her body to match with the surrounding environment, allowing for sneak attacks.

Trivia

 * Since the rest of her family have similar frog-like appearances, they may also possess the same Quirk. It can also suggest that this Quirk makes the user progressively more frog-like as they age.
 * This Quirk appears to be hugely inspired by the superpowers of character, a mutant and recurring villain in the series. Ironically, whereas Toad is mostly seen as a joke, Tsuyu's abilities are often commended as extremely reliable and practical.
