Iono hosts a livestream called "Iono Zone" (Japanese: ドンナモンジャＴＶDonnamonja TV) in Paldea. She is known to stream her work as a Gym Leader, and prioritizes viewer numbers and engagement on her channel; as such, she never misses the chance to have a collaboration with another popular figure. However, her popularity is so massive to the point she has trouble casually going on picnics with her Pokémon due to all the attention she attracts. To add to her charm, Iono also has the habit of mixing languages together and moving animatedly.
In addition to the Gym Badge, Iono gives out TM048 (Volt Switch) after defeating her.
Iono first appeared in HZ015, where she was is revealed to be friends with Dot. Iono was contacted by Dot to help her find Liko, who was missing. Taking the opportunity, Iono asked Dot if she wanted to do a collaboration in her live show as Nidothing to better spread the word. With the help of Iono, Dot was able to locate Liko in Levincia. Iono then turned the search into a game of tag and later congratulated Roy for finding Liko and thanked Liko for her help in making her stream a hit.
Bellibolt is Iono's only known Pokémon. It was seen by her side when Dot called her.
Iono's Japanese Gym Leader title is エレキトリカル★ストリーマー.
Iono's hairclips resemble two Magnemite. The screws above her sternum and on her boots resemble those found on Magnemite's body. Despite this, no member from the Magnemite line is ever included in her team. However she can trade a Magnemite to the player in the Indigo Disk DLC.
