Miko

Miko is a fictional character from the Digimon franchise. Miko is a pet cat belonging to the family of Tai and Kari, and features in Digimon Adventure, as well as the movie of the same name and the movie Our War Game!. However, Miko never appeared and was never mentioned in the sequel series, Digimon Adventure 02.

Prelude to Digimon Adventure
After Kari steals Miko's food, to feed to the newly digivolved Koromon, Miko lashes out at Koromon, chasing him around the kids' bedroom and then scratching him. Miko then scratches Tai after he tries to defend Koromon.

The Eighth Digivice
Miko features prominently in the episode The Eighth Digivice, discovering Kari's digivice and ending up being chased by one of Myotismon's henchmen, Raremon. Miko eventually abandons the digivice after confronting a dog.

(The Battle for Earth)
Though Miko does not feature in this episode, an error is made in the English dub when Kari, concerning Salamon, says "What are we going to do now? They don't allow pets in our apartment", despite owning Miko.

Our War Game!
Miko is standing in front of the computer screen before the fight with Keramon, and is shooed out of the way by Tai. In Digimon: The Movie, the computer says at this point, "Thank you for visiting *meow*.com". Later on, Miko is hanging around with Tai and Izzy when they manage to contact Matt and T.K. through a video chat program.
