Nintendo TVii Mii #1 originally appeared as one of the 90 Miis to appear in the WaraWara Plaza when the Wii U is either disconnected to the Internet or can not connect to Miiverse (which nowadays, is always, as Miiverse shut down in 2017). She hasn't appeared in any game since. She, along with the other 89 Miis, can be found in a file inside the Wii U NAND named 1stNUP.xml, with her Mii data file encoded in base64.

On August 17, 2015, Wii U system update 5.5.0 removed the Nintendo TVii icon from the HOME menu and WaraWara Plaza, only for USA region Wii Us - JPN region Wii Us kept the Nintendo TVii icon and its 11 Miis, and PAL never had them due to Nintendo TVii never launching there. For USA and PAL Wii Us, the Nintendo TVii icon was replaced by the Parental Controls app icon, and 5 new Miis. Because of this, Nintendo TVii Mii #1 is one of eleven Miis that only appear on JPN Wii Us and pre-5.0.0 USA Wii Us, not on PAL or post-5.0.0 USA consoles.

As with all WaraWara Plaza Miis, she was originally made on a Wii U/Switch (4), her creator name is NINTENDO, her Mii name in her Mii data file is NINTENDO, has Copying turned on, and Sharing turned off. Her height is set to 67 and her build is set to 85.

Her Mii data file contains unused data. Specifically, her facial hair color is set to the 7th option, and her mustache and glasses are set to be moved vertically 2 down.

Like all WaraWara Plaza Miis, Nintendo TVii Mii #1 does not appear in any promo art.
