Audino is a bipedal, pink-and-cream Pokémon with oval, blue eyes. The top of its head, its back, and arms are pink, while the lower half of its face, body, ears are cream-colored, as well as its front and fingers. The patterning of pink and cream on its chest resembles a jacket. There are three digits on its hands and two on its feet. It has a puffy, white tuft for a tail. Audino has floppy ears with thin, curled extensions on the underside. It can use these ears as radars, and it has an incredible hearing ability.
The feelers on its ears act like stethoscopes in that it can feel the beat of another Pokémon's heart, in order to assess the Pokémon's feelings and overall physical condition. The feelers are also able to determine when an Egg is close to hatching. It has an incredible sense of hearing, where it can even hear a rolling pebble from a mile away. Audino is said to have a kind heart.
When Audino Mega Evolves into Mega Audino, it becomes both heavier and taller. The patterning on its stomach, now completely cream, is covered by what resembles a flared lab coat. Most of its body becomes white with pink tips in four places, one on each ear and near the edges of its "coat". Its eyes turn pink and its ears stand upright with longer, curlier feelers. Its tail becomes larger and a smaller tuft of fur is centered on its chest. Two additional, curled feelers extend from under this extra tuft of fur. White fur covers its feet with two small tufts on the heels. Mega Audino can release pulses that reduce hostility, and the secondary feelers can put those who come in contact with them into a deep sleep.
In Generations V and VII, Secret Power was Audino's signature move. Audino is the only known Pokémon capable of learning the move Secret Power by leveling up.
Audino appears as a trophy, exclusive to the 3DS version of the game.
This Pokémon has huge ears and large feelers that look like stethoscopes. It's easy to guess what it's best at! It can pick up even the faintest of sounds perfectly with its feelers, including the heartbeats of other creatures. It can even tell how far away eggs are from hatching.
Audino seems to be partially based on rabbits, with features similar to that of a physician or nurse. The stethoscope-like feelers on its ears also bring to mind a cochlea, a part of the inner ear involved in hearing, or a butterfly's antennae, or proboscis. The ears themselves resemble butterfly wings, especially in its Mega Evolved form, which may mean it was based on some depictions of a fairy. Mega Audino could take some influence from angels, as well as doctors. Mega Audino may also have a resemblance to the Sweet Lolita fashion style, having flowing, white and pink "coat", "boots", and ears, or perhaps even the Magical Girl subgenre seen in Japanese pop culture.
Audino may be derived from audio and a pun on the phrase "I dunno."
Tabunne may be derived from a pun of 多分ね tabun ne (maybe) or 多聞 tabun (hearing many things). It may also involve 耳朶 mimitabu (earlobe).
