Why can't I nickname Runerigus, Cofagrigus?

Question

I tried naming a Runerigus, Cofagrigus on my first Sword playthrough but it didn't work?

CW: slurs

Comments

I think it's because of the 3 letter F slur. I tried searching for a few minutes and couldn't find a full list of words that the Nintendo Switch bans.

100% because of what sumwun said

---

It does have fa but it follows up with a g and it's a not you know...

---

That’s precisely why

---

Oh, you really don't notice that that

---

Did you try naming it Cofagrigus, or tried to change Cofagrigus's name?

---

I didn't I googled the name

---

What? Can you please explain in detail what you mean?

---

Does that even make a difference? It’s most likely because of the slur.

Answer 1

You cannot name Runerigus “Cofagrigus” because it has a slur in its name. Even if it’s a Pokémon name it is counted as a Nickname and has to follow the rules for one.

It is for XY but it is unlikely that it is different from the Switch’s censor list seeing they are the same company
