Alyssa

Alyssa (Japanese: イズナ Izuna) is a character of the day who appeared in A Different Kind of Misty!.

She and her brother, Thatcher, have the duty of protecting the light stone, which was given to their village by a 'Legendary Hero' with a Pikachu many years ago to operate the mountain's lighthouse. She used her Magnemite to charge the light stone, allowing passing travelers to make their way safely through the heavy fog.

During the episode, she mistaked Ash and his friends as the thieves that stole the light stone (when it was actually Team Rocket), but later apologized for her mistake. She was also grateful to Ash for teaching her brother how to believe in his Plusle and Minun.

Although Thatcher reappeared in person in Cheer Pressure, Alyssa has only reappeared in a flashback.
