How do I change Chester's nickname?

Question

I got a Chespin from a trade with Shauna. But I can't rename it. I really want to re-name it because "Chester" is the is a terrible name.

Comments

Please don't use caps like that, thanks.

Like all traded Pokémon, nicknames can't be changed. You can breed it if you want a Chespin without the nickname.
