Misty's Togetic was one of Misty's Pokémon. Ash found it as a egg in Attack of the Prehistoric Pokémon. Later the egg hatched into a Togepi in Who Gets to Keep Togepi?; even though Ash won the right to own him, he thought of Misty as his mother, so it chose to stay with her. Later in Hoenn, Misty returned for a Togepi Festival. It was, however, a trick. A man named Colonel Hansen wished to steal Togepi so he could become the ruler of Mirage Kingdom. Topepi later evolved into a Togetic, defeated Hansen and saved the Togepi Paradise. In order to protect the other Togepi, Togetic stayed in the Togepi Paradise.

Master Quest Appearances Togepi was Misty's favored Pokémon and the one she looked after the most. She seemed very protective of him such as when a band of Tauros ran amok and almost trampled him, she feared for him and didn't leave until the Tyrogue rescued him in "A Tyrogue Full of Trouble". In this series, Togepi was seen as a mascot of Misty and the baby of the Pokémon group as he was seen in the other series.
Advanced Challenge Appearances In Hoenn's series the famed mascot of Misty was given more depth to its character. Misty doesn't know that Togepi has saved Misty and the gang's life a few times.
It is possibly the Togepi set to reappear in the Pikachu short airing along with the 15th Pokemon movie.
