Frogadier is a light-blue, bipedal, frog-like Pokémon. A dark blue marking covers its head and forms a three-pointed mark down its upper back. Its eyes have yellow sclerae, black irises, and white pupils. Its eyes protrude slightly from the top of its head and each has a backward-facing spike above it. It has a white bubble scarf, dark blue hands and circular toes, and white circular fingers.
Frogadier is a nimble and swift Pokémon; it can scale a tower exceeding 2,000 feet (600 meters) in one minute. It can also throw bubble-coated pebbles at targets up to 100 feet (30 meters) away. It can confound opponents by leaping about ceilings or into trees.
Frogadier is based on a frog. Considering its crouched pose, dark blue "hooded" face and upper body, as well as its scarf-like foam, Frogadier is more than likely based on a ninja as well. The spiked protrusions above its eyes may have been inspired by horned frogs from the generaMegophrys and Ceratophrys. Its bubbling white foam is a reference to frog foam nests, created by some species such as the túngara frog and grey foam-nest tree frog to protect eggs.
Frogadier was shown in the anime to be able to run on the surface of water, which could be a reference to ninjas supposedly being able to walk on water using mizugumo.
