Mii changed on my 3DS

Mii changed on my 3DS - Inscription My body my rules against gray background

So I have had my 3DS for about three years now as well as a Nintendo Network ID. My little brother was recently given a Wii U and being the kind older sister I am, set it up for him on my Nintendo ID.

Well, about a week later, my Mii on my 3DS changed to the one he has on the Wii U instead of my own and I can't seem to change this. My personal settings are still the same, yet my name and character has changed.

Any help is much appreciated, thank you.

Only one Mii and username can be associated with a Nintendo Network ID at a time. If it is changed on one device, it automatically changes on the other. You have two options:

Good luck! Feel free to ask in the comments if you have any problems.

    You need to create a seperate Nintendo Network ID per person, otherwise this will happen.

    If he hasn't played on the Wii U yet, you can just delete his profile and then create a new profile with his own Nintendo Network ID. After that, you should be set your own ID's Mii again.

    If he has already played on it, then you have a huge problem now because deleting the profile will also delete all the save data. You'll need to contact Nintendo and ask if they can unlink the Nintendo Network ID without deleting the profile so that you can assign a new one. Nintendo customer service can be really frustrating to deal with though :-(
