Nanette's Tepig is a fire-type Pokémon owned by Nanette.
Tepig was being introduced by Prof. Juniper along with an Oshawott and a Snivy to Nanette. Cilan offered a suggestion to Nanette to choose Tepig to elevate the problem of her cautious nature. Tepig happily agrees with Cilan and turns towards Nanette and goes beady-eyed on Nanette. Nanette calls him cute and happily chooses Tepig and notifies Prof. Juniper. Ash proposed a Double Battle with Nanette to introduce her to trainer basics. Ash's Pikachu and Nanette's Tepig fought against Iris' Emolga and Cilan's Stunfisk. Nanette, seeing Ash's Pikachu, ordered Tepig to use Thunderbolt. Ash explained Tepig cannot use such a move. Using her Pokédex, Nanette ordered Ember, a move Tepig knows. Team Rocket appeared, since they wanted to capture Pikachu. Nanette's Tepig was able to use Ember against Frillish but unfortunate with his Tackle due to Frillish's type. Pikachu was taken away, but Tepig used Ember, causing Frillish to drop Pikachu. However, Team Rocket succeed in getting Nanette's Tepig as far as flying away in their balloon until Ash uses his Unfezant along with Pikachu to blast Team Rocket off. Tepig was rescued and given back to its trainer, who became more courageous.
