A friend created an Eldritch abomination as a Mii template for the Mii Fighters. Now since it's one of the default choices for base Miis. I can't seem to find a way to delete them.
To be clear, I am not talking about the Mii Fighters, but the actual Miis themselves.

If I understand you correctly you want to know how to delete a Mii from your Switch console wide rather than just removing them as an option from the game. To do this follow these steps:
Scroll down the options on the left and select "Mii."
Select "Create/Edit a Mii."
Select "Mii List." Choose the Mii character you want to edit/delete.
Select "Delete," then "Delete" again.
