That’s right, friends. If you must be named after a Pokémon, I guess you should be flattered that you’re an Onix. Do you think Justin Timberlake minds the nickname Trousersnake? You’re damn right he doesn’t.
Onix is actually a relatively popular name — for both genders at that.
Naturally, it’s more often spelled Onix, after the gemstone of the same name, but Onyx is a variant that sees use. This one’s a little out there, but it’s both a (somewhat) mainstream name and an awesomely nerdly Pokémon reference in one. That’s something I can definitely get behind. It's much better than naming your kid Steelix (its evolved form), at any rate.
