Narissa, nicknamed Rissa, is a character of the day who appeared in Dealing With a Fierce Double Ditto Drama!.

Narissa is a beginning Pokémon Trainer who owns two Ditto: one with regular coloration and one that is Shiny. She also owns an orange-colored Pokédex. According to her, she is called the "Rumbler" where she comes from.

Upon meeting Ash and his friends, Narissa seemed incredibly full of herself, calling Ash a "newb" Trainer before proudly announcing that she had been a Trainer for one month. She additionally claimed that she had no Badges because the Gym Leaders would run in fear of her Ditto. Also, when she was about to participate with her Ditto in a Double Battle against a Trainer's Cubone and Marowak, Narissa had them both take the form of a passing Zapdos, causing the Trainer and his Pokémon to run in fear.

Despite this tough and confident facade, however, Narissa is actually quite meek and self-conscious, as well as being a crybaby. She cosplays as Flint of the Sinnoh Elite Four, whom she greatly admires, in order to help her feel more sure of herself.
