Lillipup (Japanese: ヨーテリーYouterii) is a Normal-typePokémon introduced in Generation V. It is known as the Puppy Pokémon. Its signature move, Cheer Up, increases its Attack and Special Attack stats.
Lillipup is a light and dark tan, dog-like Pokémon, with particular similarities to a Yorkshire terrier and has a red nose.
In the Anime
Lillipup was seen in episode 15 of Pokémon Best Wishes under the control off Gym Leader Aloe. It was very friendly and playful, as it jumped into Iris's arms then ran over to Ash to play, but when the battle started, it took out Tepig with one Take Down.
In the games, the first Gym Leader has a Lillipup, whereas in the anime, the Gym Leaders only have Pansage, Pansear, and Panpour.
Lillipup's name is derived from the mythical land of Lilliput described in Johnathan Swift's novel, "Gulliver's Travels". Lilliput is where the Lilliputians live, a race of little people. This could relate to the small size of Lillipup.
